Impress with innovation
What you have here is the new edition of Bulletin – the magazine of the
Siempelkamp Group. Most of you will already be familiar with our Bulletin.
I can promise all of you who are looking at this magazine for the first time
that the time you spend reading it will not be wasted.
For it includes some fine examples of the ambitious aim of the Siempelkamp Group to provide its customers all over the world with innovative
technologies and machines designed to meet future challenges. In our
opinion this is the best way to support our customers by adding value to
their production plants, improving their processes and strengthening their
position towards their competitors with distinguished products.
tenance: the new generation of short-cycle presses exhibits significant
benefits for our customers.
Learn about the new OSB-production plant assembled by the Siempelkamp
Machinery Branch and its subsidiaries and associated companies in Broken
Bow, USA. Once again we were able to reach a milestone and even to set
a world record: the core element of the plant includes a 60.3 m long
ContiRoll® press. No other plant is equipped with a similarly long and
therefore extremely productive continuous press.
Finally, I would like to report on another record: driven by our customers’
demand for even more productive plants an engineering team
with members of Siempelkamp’s Machinery and Foundry Branches
developed the largest multi-daylight press of the world. The plant is being
under construction and shall render an annual output of more than
700,000 m3 of OSB. Such an output was only dreamed of in the recent
past.
By no means less remarkable is the latest innovation of our associated
company PAL S.r.l.: the QuadradynTM for the fractionalisation of strands
used for OSB-production. This is a genuine alternative to the drum screens
previously used, rendering better quality and appearance of the products.
We have also continued to optimise our short-cycle technology, resulting
in an improved surface quality of the board and a more efficient main-

Dr. Hans W. Fechner
And this is not the end of the list of our recent innovations ...
Not only is our subsidiary Wenutec the international market leader in the
manufacture of stud-tensioning machines for nuclear power stations. It
was also able to establish itself in the huge market of modernisation and
retrofitting with an order on the modernisation of the stud-tensioning
machine completed in the French nuclear power station of Cattenom.
I am optimistic that I have not promised too much and hope to have convinced you of the potential of innovation within our group of companies.
All enquiries concerning our new technologies and machines will be
highly appreciated!

The economic situation in Thailand in 2004
Thailand has made a very fast and sustained recovery from the terrible economic crisis of 1997/98. All indicators point
to growth, and the political situation is stable.
By Ralf Griesche, G. Siempelkamp GmbH & Co. KG
After growing by 1.9% in 2001 and 5.2% in
2002, GNP performance was very strong in
2003, increasing by 6.3%. Domestic demand
was and continues to be the main driving force
behind GNP growth, and this is reflected in
strong private consumption and investment
figures. The positive trend is fueled by low
interest rates and generous credit terms from the
banks. The unemployment rate is about 2.5%,
and inflation is less than 1%. These very positive
The lively city of Bangkok is Thailand’s
economic center
economic conditions are expected to improve
further in 2004. GNP should increase by 6.5% –
7.5% depending on the price of oil. The
construction industry is one of the top growth
sectors in Thailand. Domestic demand is high as
a result of government incentives for consumers
to buy their own property.
Exports also contribute to strong economic
performance. The US dollar exchange rate is
very favorable, making goods and services priced
in baht attractive on international markets.
Following the economic crises in Asia in 1997/98
which emanated from Thailand and brought
the country to the brink of disaster, current
conditions provide a solid basis for economic
performance in the years to come.

The situation in the wood-based materials industry in Thailand
The good economic data are also reflected in a positive investment climate in the wood industry. Last year, Siempelkamp sold
4 new particleboard plants with state-of-the-art technology in Thailand. Another plant was fully redeveloped following fire
damage, and a second plant is to be modernized in 2005. Reason enough to travel to Thailand to discover the trends in particleboard production.
In light of the general economic picture described above and given the conditions in furniture and interior decoration sales channels, the
current situation in Thailand is very satisfactory.
The Agency for Real Estate Affairs expects the
housing market to increase by 30% in 2004. The
market for office buildings in the greater Bangkok area will grow significantly. These factors,
combined with an increasing willingness by the
majority of consumers to spend, have given new
impetus to the furniture industry. Most of the
2,400 companies are very small. 90% of what
they produce is made of wood, and 70% is
exported. Forecasts indicate that exports will
increase substantially in 2004 (exports in 2002
totaled 382.6 million euros).
Following the large increase in demand for
wood-based materials, the industry has made
massive investments in new capacity during the
past two years. Siempelkamp Maschinen- und
Anlagenbau has played a leading role in the
expansion of particleboard production. Four
new plants will be handed over to the customers
in 2004 (Vanachai, Green Panel and Metro –
Rayong will follow by November 2004). Annual
particleboard capacity will double to more than
2.7 Mio. m3. Despite the rise in demand, there
are a lot of unknowns in this scenario. Additional
production capacity may turn a seller’s market
into a buyer’s market. This was reason enough to
pay a visit to this booming market, so that we
could get an impression of what is going on and
condense the findings into this report.

Somporn Pisolpool,
President,
Rayong Particle Board Co.,
Ltd.
Piya Piyasombatkul,

An assessment of what the future holds for the particleboard
sector following the greatest expansion in the industry’s history
On our trip through Thailand we had the opportunity to talk with the plant owners of the new particleboard plants. We were
especially interested in learning about the economic conditions and the market chances for the manufacturers, who drastically
boost up their output.
The first question was naturally about the current
economic situation and the outlook for the next
two to three years.
Everyone agreed that the economic crisis was
definitely over. Confidence has returned across
the board, and economic recovery will be
mainly based on domestic demand. There is also
scope to increase exports due to the torrid pace
of growth in neighboring China as well as the
improved state of the world economy. Some
minor concerns about the future were raised.
Growth will slow down if oil prices remain at
$45 per barrel. Other factors include the rapid
containment of epidemics like SARS and avian
influenza as well as general developments in
China, which has become the center of gravity
in Asia due to the sheer size of the Chinese
economy.
The persons we talked with do not expect to see
a reoccurrence of a crisis similar to what happened
in 1997/1998. Lessons have been learned which
will enable the country to react faster in the
future. Industry also has a high level of
confidence in Prime Minister Thaksin Shinawatra,
a former businessman who has been in power
since 2001.
There were various views on what factors led to
a 100% increase in particleboard production
within the space of a year. Depending on the
direction of their marketing activities, some companies will export most of their panels, whereas
others plan to sell the new products primarily to
the domestic furniture industry. In assessing the
market, all agreed that a shortage of particle-
board had resulted in higher prices. In addition,
there are only two companies who are using
ContiRoll® technology (the most modern equipment, which delivers the lowest cost per piece).
This equipment gives producers high flexibility in
terms of technology and panel sizing. Investment
in advanced technology of this type gives
companies a competitive advantage which may
cause competitors to lose market share. The
furniture industry is expected to experience
double-digit growth in the next few years,
because there is a significant demand backlog
for low-cost furniture in the country, and it will
take a few years to satisfy pent up demand.
Furniture is largely made of particleboard. A
second explanation is increased export capability
in the Thai particleboard industry. Following
the devaluation of the baht by two thirds as a
result of the economic crisis, the panels are
priced very attractively even when they have to
be transported over long distances. In addition,
Thailand is the only country in Southeast Asia
that has expanded its particleboard production
capacity. China has invested primarily in MDF
capacity. To summarize, the general impression is
that producers are not concerned about their
ability to fully utilize new capacity to service
export markets and/or to meet domestic
demand.
Time will tell whether small producers, who use
older equipment to produce lower grade panels,
will disappear from the market. They have the
option of offering low prices, and inferior
quality is often acceptable in regional markets.
However, if the increase in supply pushes prices
down, small producers will have sufficient finan-
cial resources to invest and could disappear from
the market in the medium term. They will also
have difficulty accessing export markets. Price
and quality competition may possibly drive some
companies out of the market.
Those who took part in the discussion
agreed that the expansion of capacity will increase the significance of the export business
compared to domestic consumption. It is
estimated that up to 70% of production
output could be exported and the other 30%
will be used for domestic consumption. 95% of
particleboard are exported as raw boards. The
main customers are in China, South Korea,
Taiwan, Vietnam, Malaysia, Indonesia, the
Philippines and Japan.
It is of course the furniture industry that drives
demand for particleboard. Domestic demand
collapsed in the aftermath of the economic
crisis, and the furniture industry was forced to
look for new markets outside the country. This
made the industry stronger, and today 70% of
furniture output is exported. In addition, some
countries with high labor costs like Japan, where
there is also a shortage of raw materials, have
moved production to Thailand. There is no doubt
that everyone will take advantage of the supply
base for particleboard in Thailand, which is now
the largest producer in Southeast Asia.
In Thailand, finishing work on wood-based
panels is performed primarily by specialists who
are not in the panel production industry. Large
producers are only beginning to realize the
opportunities that they could exploit by expanding the value add chain. Because 95% of the
SIEMPELKAMP
panels are used by the furniture industry,
finishing work is performed on all of these
panels. The cheapest finishing methods use 20
gr. paper (LBWP). It is by far the most common
technique, and it is used on 80% of all finished
panels. Of the remaining 20%, 10% is low pressure melamine (LPM), 5% veneer and 5% other
finishing techniques. Most of the LBWP panels
are used in cheap knock-down furniture, which
is the leading category in the product mix.
Another potential application for particleboard
is loudspeaker production. Many audio manufacturers have created production capacity in
Asia. Only one person sees an opportunity in
the flooring market. Everyone else believes that
there is no market in Southeast Asia for laminate
flooring due to the climate. Interior decoration,
on the other hand, could be a growth market,
particularly in construction of high-profile
hotels and office buildings in Bangkok and
the surrounding area where particleboard
could gradually replace plywood as a base
panel. We had the opportunity to admire the
first successful implementation in the lobby of
the J.W. Marriott Hotel in Bangkok.
Labor costs are increasing in Thailand. Particleboard could replace work-intensive applications
in framed doors, etc. in the future. Particleboard
will replace some production of solid wood and
plywood products in the medium term. Nevertheless, none of the participants could imagine
that OSB would replace plywood anytime soon.
One reason for this view is that these manufacturers have a background in plywood production
and still produce or sell plywood today. The fact
that plywood is currently made by many familyowned companies with minimal equipment,
making production very cheap (OSB does not
have a price advantage), is a very convincing
argument. On the other hand, there is a decreasing supply of suitable lumber in Thailand,
and it is only a question of time before the new
product OSB becomes an important product in
this country as well.
It is hard to say whether MDF will be as successful as particleboard. Large quantities of MDF are
produced in the country, and the outlook is good
because MDF will be used to an increasing extent
as a replacement for solid wood. It might also be
used as laminate flooring. A lot depends on
China, which is building up large capacity. Only
time will tell.
Finally, there was a discussion about the
availability of wood as a natural resource. It
is important to realize that in the southern part of
Thailand where the majority of particleboard
plants are located, rubber trees provide nearly
100 % of the raw material used to produce
particleboard. The trees are of course used
primarily for rubber production on plantations,
and the government pays subsidies to preserve
the trees. Old trees, which no longer produce latex
and need to be replaced, were burned in the past,
and this caused the well-known CO2 problems.
The particleboard industry makes a meaningful
contribution to the ecology by turning a large
portion of “waste wood” into panel products.
This scenario makes it unlikely that there will be
a scarcity of raw material. Currently more than
2.2 million hectares are cultivated, and 3% of that
must be replaced annually through new
planting. Even if rubber production were to cease,
there is no doubt that new resources could be
activated for many years to come.

Company background and brief profile of the new particleboard plant
Vanachai Group Public Co., Ltd., Bangkok
Vanachai was founded 1943 and was
originally a saw mill. The company got
into the plywood business in 1966
and installed a particleboard line for
the production of wood-based panels
in 1979. The initial system was supplied
by Siempelkamp. Vanachai has been
producing MDF panels in Chonburi
since 1994. The company went public
in 1995, and when it built another
particleboard plant in 1997, it became
the largest wood-based materials producer
in Asia. Vanachai has been operating
a new Siempelkamp production line
since May 2004, and it now has an
annual output of more than 1.2 million m3
of wood-based materials.

Hatyai Panel Co., Ltd. and Siam Fibreboard Co., Ltd.
If you ever go over to see the Siempelkamp lines
in Thailand, be sure to visit the Siempelkamp
lines on the Malaysian border, which have an
interesting history. Between 1990 and 1995, STA
in the person of Mr. Supotphong Vilaipun invested about 1 billion baht in a one-of-a-kind
wood-based materials complex. The company
installed 2 particleboard lines and 2 MDF plants
each using Siempelkamp ContiRoll®-technology
as well as 4 short-cycle press lines which were
also supplied by Siempelkamp. The complex also
included plywood production and various furniture manufacturing operations. Before the complex could be completed, the owner died in a
tragic accident. Several attempts to keep the
business going failed because of the high level
of debt. The particleboard and MDF lines were
sold at auction in 2004. Hatyai Panel Co.,
Ltd. currently owns the 2 particleboard lines and
the short-cycle presses. Siam Fibreboard Co.,
Ltd. is the owner of the two MDF lines.
Hatyai Panel belongs to Mitr Phol Sugar Group,
the largest sugar producer in Asia which already
runs a particleboard line that uses bagasse as a
raw material. Siam Fibreboard was taken over by
the successful Malaysian MDF producer Evergreen Fibreboard. Siempelkamp provided some
assistance during re-commissioning of the first
MDF line which is now operating successfully
again. The second MDF line was only about 80%
complete when work stopped due to the crisis at
STA in 1996. The line will be finished and go into
operation in 2005. The same day that Hatyai
Panel took over the particleboard line, the larger
of the two particleboard lines was heavily damaged in an arson attack. The controller room and
the ContiRoll® were completely destroyed in the
fire, and the line lay idle. A team of specialists
from Siempelkamp has been working since
March to refurbish and modernize the line. The
first panel was produced in September 2004.
The older, smaller line will be refurbished and go
into operation in 2005. This would bring the
Hatyai wood-based materials center back to life.

The official opening of the Vanachai particleboard line
in Surat Thani
We were very happy that our stay in Thailand coincided with the formal opening of Vanachai’s new particleboard
plant. The Honorary Dr. Dieter Siempelkamp also came from Germany, looking forward to participate in the
opening of a new factory, the machines of which bear his name.
One of the highlights of the trip to Thailand was
an invitation to attend the opening ceremony for
the new Vanachai line. Two jumbo jets took off
from the airport in Bangkok at 6:30 a.m. on
August 23, 2004 and headed in the direction
of Surat Thani, which is about 600 km south of
Bangkok. The planes were carrying some of the
guests from the Bangkok area who had been
invited to the ceremony. As is customary, the
group included a number of monks who were
to play a major role in the events. During the
opening ceremony, they called down heavenly
blessings which they asked to be bestowed on
a perpetually prosperous company. As Western
observers, we were surprised and pleased to
witness how readily the Buddhist religion supports a person’s business interests as well. The
monks were of course guests of honour among
the 1,200 persons who were invited to attend.
Next on the agenda was a big banquet for
everyone followed by a tour of the new plant,
which had been spruced up for the occasion.
Given all of the well-wishing, the venture is sure
to be a success.

While the North American and European nonstructural panel industries are struggling, China
has grown to become the dominant producer
and consumer of MDF, and is on the verge of
becoming the largest market for particleboard
as well. This change is driven by a booming
domestic economy, a shift in furniture production from the United States, Europe and other
Asian countries to China, and the emergence of
China as the world’s largest exporter of furniture.
30% of production capacity, medium and larger
scale mills have driven the recent expansion. In
2003, medium sized mills with a capacity of
35,000 to 100,000 m3 represented approximately
37% of total production capacity, and mills with
a capacity of more than 100,000 m3 represented
33%.
Based on expansion plans already announced,
MDF production capacity will increase by a further
29%, to over 16.2 million m3 by 2005.
MDF Production
Particleboard Production
China has experienced massive growth in
medium density fibreboard (MDF) production
capacity over the past five years, from 4.8 million m3 in 1999 to 13.2 million m3 in 2003, an
annual growth rate of 29%. With 278 production lines it is now the largest producing country,
larger than Eastern and Western Europe combined
(12.4 million m3) and more than twice the
capacity of North America (4.9 million m3).
Much of the production capacity developed in
China prior to 1999 consisted of smaller mills
with a capacity of less than 35,000 m3. While
these smaller mills still represent almost
In contrast to the spectacular growth in MDF,
particleboard production capacity in China increased from 5 million m3 in 1997 to 5.4 million m3
in 2003, growth of just 1% per annum. The
addition to capacity over the five years to 2002
was just 355,000 m3, most of which was added
in 2002.
There are estimated to be between 800 and 900
particleboard mills in China, in contrast to the
278 MDF lines. Of these, over 800 are very small
mills with a capacity of less than 5,000 m3 per
annum, and a total capacity estimated to be
800,000 m3. The remaining 72 mills had an
estimated production capacity of 4.6 million m3
in 2003, and ranged in size from just over
5,000 m3 to 100,000 m3, but most had a capacity
of less than 100,000 m3.
Over the next five years particleboard production
capacity in China is projected to increase at a
stronger annual rate of 4%, from less than
5.4 million m3 in 2003 to over 6 million m3 in
2008. Even with this modest growth, China will
become one of the largest particleboard producing countries over the next five years.
The many small facilities will ultimately be replaced
by larger mills. Of the nine known planned mills,
the largest one will have a capacity of 300,000
m3, one 150,000 m3 and one 100,000 m3. An
additional five mills will have a capacity of
50,000 m3, and one will be 30,000 m3.
Excluding the smaller mills (less than 5,000 m3),
Heilongjiang province had a production capacity
of over 400,000 m3 in 2003, the three provinces,
Jilin, Guandong and Shandong over 200,000 m3,
and the provinces Henan, Shichuan, Inner
Mongolia and Hubei between 100,000 and
200,000 m3. Most of the expansion over the near
term will be in Fujian, which will become the
second largest producing province, at over
300,000 m3 by 2005.
It is possible that production capacity could increase at a significantly stronger rate than 4%, as
projections for growth in consumption suggest
that there is scope for adding considerably more
16 | 17
to capacity, but growth is unlikely to be as
spectacular as the growth in MDF production
over the past decade, unless there is a rapid
shift in consumption to particleboard, which is
possible.
Drivers of consumption
The rapid growth in MDF and particleboard production facilities over the past decade was driven
initially by furniture manufacturers that relocated
from Taiwan beginning in the mid 1990’s, and
later by companies from other regions, including
North America and Europe. These companies
began shifting their production facilities at a time
when in most countries, MDF was booming, and
replacing the older, less versatile products such as
particleboard and plywood.
As they shifted their production facilities to
China, the furniture manufacturers from Taiwan
moved their production techniques with them,
including the extensive use of MDF in furniture
production. In Taiwan at this time, furniture
manufacturers were rapidly replacing particleboard with MDF as the key material used
for furniture production. The furniture manufacturers that relocated to China created strong
demand for MDF in China. As a result, MDF
production as a percentage of total wood panel
production in China increased from 6% in 1997
to 25% in 2001.
was not the case in South Korea or Taiwan,
where MDF has always been more extensively
used than particleboard.
In some countries, including Taiwan, and South
Korea, many furniture manufacturers have turned
to using particleboard for some applications
where MDF had already replaced particleboard,
particularly applications for which the qualities
of MDF, such as smoothness of surface is not
required. Since then they have been using
particleboard. This could increasingly occur in
China over the next decade, as furniture manufacturers will be seeking more cost-effective
methods of production.
The domestic demand for furniture in China is
strong, and will continue to strengthen as
China’s economy expands. China has also
become the world’s largest exporter of furniture.
As furniture manufacturers from a wider range
of countries establish production facilities in
China over the next decade, there will be ample
opportunities for expanding particleboard
production capacity in China.
In the mid-1990’s almost all MDF was used for
furniture manufacturing. By 2003, it is estimated
that 65% was used for furniture manufacturing,
15% for building materials, 10% for flooring,
and 10% for packaging and other uses. MDF
over the past decade has also penetrated end use
markets other than furniture manufacturing,
and this has resulted in further expansion of
production capacity. In contrast, 85% of all
particleboard consumed in China is still used in
furniture manufacturing, and 15% is used in
construction and other industrial uses.
MDF consumption in China was estimated to be
over 14 million m3 in 2004, compared to 6 million m3 of particleboard. This is a very unusual
pattern of consumption, as in most countries,
particleboard significantly exceeds MDF consumption. In Japan, for example, particleboard
consumption is almost double MDF consumption, as it is in North America and in Europe.
Other major exceptions are South Korea, and
Taiwan, where MDF consumption is slightly
higher than particleboard consumption. In most
other countries particleboard was an established
product well before MDF was introduced. This

Manufacture of large components is taking to the road
Nearly everybody has moved at least once somewhere along the way. Furniture and household effects have to be packed, carried, assembled and placed in at the
new location hopefully in good order and without any losses. The result: despite elaborate preparations, chaos and alarms and excursions barely can be avoided.
It takes some time until everyday course of business will have returned.
By Dr. Wolfgang Steinwarz, Siempelkamp Nukleartechnik GmbH
Big CASTOR® spent fuel cask mounted on a long turning lathe
Now, try to imagine the corresponding basic
conditions for moving of a complete large
component manufacturing plant: limitation of
production losses to the absolute minimum,
disassembly and re-assembly of large dimensional machines and components for handling
parts weighing up to 200 tons, always acting in
compliance with the high quality requirements in
nuclear technology and adhering to the budgetary scope determined, while imponderables
were overhanging the whole period of transaction.
Exactly this logistic task the SNT-team was facing
when in the middle of 2002 the board of directors decided to consolidate in one production
centre the areas of machining of unfinished
castings like e. g. CASTOR®s, MOSAIK casks and
elements for wind power plants, which so far
were operated at different locations. The objective
was: improvement of the market position by
integrated production, taking advantages from
various synergies, like focussing know how,
reduction of interfaces, realization of optimal

cost structures as well as efficient arrangement
of machines.
As new site, a production hall was offered for
rent, which is located in Mülheim/Ruhr, not far
from the previous machining hall for CASTOR®s,
and which was used up to now by SIEMENS for
the production of turbine housings. The utilization of a part of this hall by our main customer
for CASTOR®s, GNB, made this choice particularly
interesting. Already two years ago, GNB had
moved out of the “old” CASTOR® hall which
they had used together with Siempelkamp for
more than a decade. Thus, the previous arrangement (reduction of transports, direct contact to
the customer, simplified management of the
whole process), which was advantageous for
both parties, could be continued.
After signing the lease contract on October 16,
2002 as well as the contract of purchase for
taking over various machines and equipment
from SIEMENS, the removal was planned in
detail. In summer 2003, the first remodelling
works could start. In the beginning of december
2003, a considerable part of the managing and
production staff moved to Mülheim. By applying
particular models to manage shifts and production, using reserve machinery capacity,
significant time-related production losses could

be avoided. The first chipping, visible sign of
having taken up production, hurtled in the end
of January 2004. The last phase of the removal,
including the second CASTOR® large lathe
started in for May 2004.
With the official opening ceremony on October
15, 2004 an exiting, but always interesting
chapter will be finalized. Despite lots of stress,
the logistic task of the removal also brought
about many new positive experiences, technically,
strategically and humanly. For team spirit was in
the foreground right from the beginning. And
soon, everything will presumably be going back
to normal ...!

New OSB plant in Broken Bow, USA exceeds all expectations
The Siempelkamp Group of companies together with J. M. Huber Corporation demonstrate market leadership
By Stefan Wissing, Siempelkamp LP, USA
It’s not a big surprise, but yet always impressive:
A new record has been set in the “young”
OSB business. 60.3 m in length is the latest
continuous ContiRoll® press installed at the new
plant of Huber Engineered Woods in Broken
Bow, Oklahoma. The Siempelkamp Group of
companies with all its subsidiaries and holding
companies can claim this state-of-the-art
achievement. Again, Siempelkamp made it possible to write a piece of technology history.
Huber Engineered Wood – a family-owned
company
Huber is based in Edison, New Jersey. The
product spectrum of the company ranges from
raw materials, to specialty chemicals and forest
products, to building materials. One significant
At the crossing of highway 70 and highway 259,
Broken Bow with its just about 5000 inhabitants
hardly ever finds itself in the media spotlight.
Broken Bow is a typical small American town in
the Middle West. The town is idyllically located
in between lakes and creeks, woods and mountains. The neighboring State of Texas across the
Red River and the State of Arkansas are only
within a stone’s throw.
J. M. Huber Corporation is a well funded
medium-sized business in the USA. It is not
noted at the stock exchange and completely
family-owned. The name “Huber” is of German
origin. When Joseph Maria Huber from
Munich went on his first business trip to New
York City in 1883 nobody on both sides of the
Atlantic Ocean dared to imagine that the
business would one day reach a turnover of
$1 billion.
Andy Trott, President of Huber Engineered
Woods, is proud of all that has been achieved.
Up to now the unit was in charge of four plants
producing “Engineered Wood Products” mainly
for the home construction market. Now, there is
a brand-new plant in Oklahoma. Construction of
the Broken Bow OSB plant, an investment of
more than $130million, started in 2002.
For Huber the Broken Bow plant is the first
investment located away from its plants on the
East Coast. The new plant has an almost ideal
location. This is not only due to the large supply
of Southern Yellow Pine in the east but also the
widespread acceptance of this investor in a
structurally weak but resource-rich area.
Oklahoma – The Sooner State
Even though the state of Oklahoma is rich in
wood jobs are scarce. However, Oklahoma is
called the “Sooner State” for a good reason:
Back during the settlement ages, settlers didn’t
think long before they settled in Oklahoma. In
the “Sooner State” people are alert and very
decisive. They are willing to make quick decisions
even when it comes to large investments such as
the new Huber OSB plant – as city manager
Mark Guthrie points out.
business unit of the multinational company is
Huber Engineered Woods LLC. Headquartered
in Charlotte, North Carolina, this group has
developed into one of the most innovative OSB
producers in North America.
Though Huber is a company that focuses on
environmental acceptance when it comes to
making decisions, Broken Bow and McCurtain
County also support investments that create jobs
and revive the infrastructure. The Huber plant
will employ approximately 150 workers once it
has reached full capacity.
Welcome to Oklahoma
Trust and accountability are major
business principles
An investment of this scale works like a magnet:
more than 250 jobs are created in the area, for
example, in the service provider sector. As a
result $25 million will yearly be flowing into the
financial cycle of the town, county and state.
Andy Trott describes the close relationship
between the company and the region in the
following way: “We are not just a company in
Oklahoma. We are friends and neighbors who
wish for this state to grow and flourish!”

Congratulations: The Huber Team is proud of the first board produced on April 13, 2004
The ultimate business principle of Huber is to
build trust. This does not only include making
the right choice for a location but also selecting
reliable partners who help to lead this and the
other investments of the group to success. Those
partners are suppliers from different sectors, for
example, plant engineering and construction,
controlling and information technology, construction and assembly, and the service industry.
After the assembly of four OSB plants – in Easton

This positive attitude of all partners has also
worked for Broken Bow. Just as in all the above
listed plants the making of the heart, brain,
veins, and all other vital organs of the Broken
Bow plant was commissioned out to a group of
companies that had delivered excellent services
in the past. Siempelkamp from Krefeld in

would say that’s typical for the “Sooner State”
one could also say that’s typical for the “Sooner
Siempelkamp Company”.
However, excellent quality and integration of the
latest developments are only one side of the
coin. When it comes to a reliable partner also the
soft factors, for example, punctual deliveries or
making the impossible possible, play a big role.
Siempelkamp’s goal is to always set a good
example and be a reliable business partner.
Büttner, for example, constructed a dryer, the
size of which did not allow a transport in one
piece. Therefore, separate segments were
delivered which were put together to the 209 US
tons giant at the construction site.
A big fish: 620 MMSF (3/8”) (550,000 m3)
OSB to be produced annually
The first board was pressed on April 13, 2004 –
less than a year after start of installation. This
achievement fits in with the “Sooner” image:
“Sooner Oklahoma”, “Sooner Huber”, “Sooner
Siempelkamp”.
The production output at Broken Bow is remarkable. Ed Milburn, plant manager, points out
with pride that 1.88 million sqft, 3/8” (1,660 m3)
OSB, is planned to be produced daily on the
press. The annual output sounds even more
impressive. 620 MMSF (3/8”) or 550,000 m3 OSB
are to be produced on the press yearly.
Leadership in Drying
For the production of this vast amount of OSB
the first technical challenge is the drying of
the wet strands. Büttner Drying- and Environ-

mental Technology, a Siempelkamp subsidiary,
solved this task. As a supplier to the industry for
almost 200 years, Büttner is the recognized
leader for drying of strands for OSB and other
wood-based engineered products. The Broken
Bow plant's demand for dried material requires
2 single-pass drum dryers. Due to transportation
difficulties with drums of the size required,
Büttner had them delivered in sections for final
assembly on site.
Nobody is perfect,
except for QuadradynTM
The Quadradyn™ – an OSB screening innovation
by PAL – has its world première at Broken Bow.
The latest development of the Siempelkamp
affiliated company screens the strands on a
roller system. The separation of the strands
into fines, core and face is precise and the composition of the future board is thus more homo-
Good access to the hydraulic valves.
The design of the press assures low maintenance
genous and better structured. The fines are then
super-screened with an oscillating screen and
once again fractioned into fines for fuel and fines
for recovery. The latter can be added back to the
core layer forming process after separate blending (Fines Recovery System). Quadradyn™
excels at its high flexibility, low maintenance and
plug-free operation.
After the dry-strand bins the Siempelkamp
Group is at play again. IMAL supplied the
blending system for the fines and the density
and thickness gauges in the pressline. The mat-
forming station was supplied by CMC Texpan.
Each of the mat formers screens the strands by
means of the typical Siempelkamp design in such
way that the largest strands are placed to the
outer face of the mat, where they contribute
most to the stiffness of the board.
The formed mat is directed through electromagnets and a metal detector. Thus, metallic
impurities are removed. Finally the edges of the
strand mat are trimmed and before the mat
enters the press it is checked by a traversing x-ray
mat density gauge (supplied by IMAL).
SIEMPELKAMP
World record: The 60 m ContiRoll® press
for Huber
The detailed engineering of the whole plant was
realized by CPM Consultants Inc., Vancouver.
The center piece of the plant is the 8.5’ x 60.3 m
(198‘) ContiRoll® press with mat pre-heater
system and screen imprint. The patented preheater ContiTherm® is one of the plant’s highlights. It has been installed now already four
times throughout the USA in Siempelkamp lines
with ContiRoll® press for OSB production. A mixture of hot air and steam is applied to the mat
directly before it enters the press. Pre-heating the
mat in this way results in an increase in press
capacity. By means of adjusting the ratio between hot air and steam the target temperature
of the mat is precisely set. The mat is plastified in
the pre-heater reducing the specific pressure
needed in the ContiRoll® press. In addition the
moisture content of the mat is raised resulting
in lower thickness swell of the board and
better board properties.
Some products require the typical screen imprint
on one side of the board. Siempelkamp equipped
the press therefore again with the patented
wire screen structuring belt system. If needed an
endless structuring belt is running together
with the top steel belt through the press. This
produces a perfect screen imprint, which is
identical to what customers are used to seeing
from boards made on multi-opening presses.
This system now runs successfully in 4 ContiRoll®
lines in the USA.
In addition to the 7/16“ thick OSB mass product
the plant also produces very specific products,
for example, the 23/32“ premium sub-floor
“AdvanTech”. Due to the high flexibility of the
ContiRoll® line board density and board properties can be adjusted in a wide range.
Trimming and board storage
After leaving the ContiRoll® the endless board is
taken over by machines and equipment which
have been delivered by SHS (Siempelkamp Handling Systeme). The endless board is trimmed on
both sides and then cut to size with a double
diagonal saw. The final master board size is
typically 8’ x 24’. For the production of rim
boards, the master board length can be reduced
to 12’. After a first quality check, the boards pass
a reject station before they are cooled in two star
coolers. The boards are then sorted and stacked
according to quality and transported to the intermediate storage area.
The intermediate storage area utilizes a fully
automatic crane system. The storage system
serves as an OSB curing area and is also used to
distribute the output from 3 shifts of press
production to value-adding processes, such as
sanding, cut to size and T&G, which run only in
2-shift operations. The warehouse management
system allows the operators to directly retrieve
stacks from either the sanding line controls or
the book saw control system. There is no operator required in the crane area to store or retrieve
stacks. The storage system also allows for restoring of cut-to-size boards after they have been
processed through the book saw system.
The sophisticated controls system for this area is
supplied by ATR Canada (today Siempelkamp
Canada Inc.) – one of the Siempelkamp Group
companies – which engineered together with
ATR Germany the plant automation system,
starting from the dry-bin discharge up to the
packing line.
The Book Saw: runs with the power
of a full-size car
Besides the sanding line, with its integrated
grading line (A and B quality boards), the book
saw is another important production component
at Huber. The cut-to-size book saw system can
be fed from several sources: the crane storage
system, the sanding line, or directly from the
The Press Line with ContiTherm® pre-heater. A mixture
of steam and hot air is applied to the mat from top and
bottom. The result is an increase in press capacity and
better board properties
24 | 25
The book saw by SHS is responsible for the
precise and quick cutting of the masterboards.
Saw motors of 100 HP allow to saw books with
a height of up to 260 mm (10”) in one cut
master board stacker. The high production capacity of the book saw is achieved by processing
of a “book” of master boards with a height of
up to 260 mm (10“). This saw’s motor power is
about 100 HP – as much as the engine of a fullsize car.
The book saw excels in its versatility. Rim boards
can be produced and then transported directly to
the rim board packing line. Thus, the boards can
be processed and packaged in their standard
height of 260 mm (10“) without further cuts.
Other OSB finished goods (commodity products)
are cut-to-size according to operator-selected
cutting patterns. Cut-to-size books of boards
leave the book saw and are stacked by means of
rake stackers. The OSB stacks are then separated
by a stack separation unit and are transported by
a stack transfer cart to one of three (3) packing
lines, the Tongue and Grove line, or back into the
crane storage system.
The Tongue and Groove Line (T&G) utilizes
Siempelkamp’s board separation system to operate at high production speeds. The board separator eliminates the gap between boards, which
significantly improves the cycle time of boards.
In addition, without board gaps, the quality of
the T&G is improved since break-outs at the
board edges occur far less often.
Sophisticated products for the home
construction business
The above-average flexibility of the Siempelkamp machines used at the OSB plant for Huber
Engineered Woods makes an above-average
product spectrum possible. The complete assortment of goods is of high demand. On the
American market, OSB is widely used in the construction business. The prognosis for OSB continues to be good, not only for the construction
business but also in the “do-it-yourself” sector.
For the last twenty years, Oriented Strand Boards
(OSB) have experienced a similar victorious
development as MDF or as particle board since
the sixties. While in North America in 1985 about
4 million m3 (4.5 billion sqft) of OSB were produced, in 1993 the number had already increased to about 9 million m3 (11.3 billion sqft).
Then in 2002 the 20 million m3 (22.6 billion sqft)
mark was crossed for the first time.
61 plants in the USA and Canada cover about
70% of the North American building materials
market for home construction with OSB. This
means each American home is statistically made
up of 6.4 m3 (7,200 sqft) OSB. In North America
the OSB market is huge! Europe is following this
trend with average OSB production increases of
over 30%.

The men behind the machines
The present series is to introduce those men of the Siempelkamp group to you who have an important influence on the development of new machines, techniques
and technologies. Their vision, their technical expertise and their assertiveness make Siempelkamp the No. 1 manufacturer in the world market of machinery for
wood-based panel production
By Ralf Griesche, G. Siempelkamp GmbH & Co. KG
The boss
Romeo Paladin, President of PAL S.r.l., Italy
Romeo Paladin is a man who knows what he
wants. He spends most of his energy on his
enterprise which he started modestly, making it
the market leader in the raw-wood processing
industry.
Wherever you see a plant for the production
of particleboard, MDF and OSB it probably
contains machines from PAL in Ponte di Piave
in Italy. They master the process of wood preparation from disintegrating to fractionalising
fresh wood up to processing of re-cycling wood
in complete plants. Romeo Paladin has pushed
forward the development of new machines with
his intuition for the market demands.
A milestone in this development is the new
strand classifier Quadradyn™. It ensures efficient
fractionalisation of strands for the surface and
the core layers of OSB and the discharge of
fines and dust.
Bulletin talked with Mr. Romeo Paladin about
his company and the new Quadradyn™:
Mr. Romeo Paladin
How did you become a machinery and plant
engineer for the wood-processing industry?
Paladin: Well that is not too difficult: if you
appreciate quality, but fail to find any adequate
machines meeting your demand, you have to
design them yourself.
That is why I founded my own company for
particle/glue blenders in 1978 on the basis of the
experience I gained for 10 years as a manager of
a particleboard company. Very soon I expanded
to design entire glue preparation and application
plants. The success with these machines gave us
confidence to invest in additional applications.
Hence we developed relatively fast disintegrating
and fractionalising machines for the particle preparation lines. We dedicated much effort to
these process steps, for as early as in this stage
the quality of the finished board is fixed.
In the 80s fresh wood became more and more
expensive in Italy; so we set about developing
machines to separate impurities from re-cycled
particles. Today, we produce integrated systems
for the particle preparation from re-cycled wood,
170 of which have already been sold. These
plants re-cycle more than 25 million t of urban
forest per year, corresponding to a surface of
approx. 4000 km2 wood per year, which need
not be felled.
To meet our customers’ highest demand for
complete solutions in the wood-processing
industry, we entered into close collaboration with
Siempelkamp in 1996 and with IMAL in 1998.

Much has been achieved within 25 years, but
please tell us about PAL’s top know-how and
expertise.
Has the latest PAL innovation – the QuadradynTM –
come into existence this way?
Paladin: We develop, design and construct
highly specialised wood-processing machines for
the production of particleboard, MDF and OSB.
Our machines are designed for achieving
maximum board qualities at a minimum of
production costs.
This cannot be done without ample investment
in R&D. In our company-run laboratory we carry
out various kinds of tests to the benefit of our
customers. On the basis of the results thus
gained, we are able to develop new machinery
Paladin: The QuadradynTM is an innovative strand
fractionalising system for the OSB-production.
We have investigated how the standard drum
screens work and found that some of them even
break the strands and fractionalise only part of
the furnish. This results in products which are
hardly of good quality and appearance. It has
been a challenge for us to improve things and
are now able to offer a real alternative to the
customer.

How the QuadradynTM works (dry screening)
28 | 29
Two QuadradynsTM at the Huber site in Broken Bow, Oklahoma, USA
How does the QuadradynTM work?
Paladin: The machine is a roller-screen design;
it consists of long elements rotating in one
direction spaced apart at a defined distance and
conveying the strands across a bed of rollers.
Dimension and size of the gaps influence the
fractionalisation of strands. This is similar to
Dynascreen for particle fractionalisation.
In the QuadradynTM, however, the elements are
not round but square (as the name suggests).
Consequently, the impacting action of the
square elements fluidises the bed of strands,
thereby enabling the fines and the dust to drop
through the bed and to be discharged out of the
furnish flow.
It therefore consists of long, perfect strands
for the surface layer and optimal strand furnish
for the core layer; the fines are eliminated
Left: face layer with big strands from the QuadradynTM
Right: face layer from a drum screen
(glue-blended and added to the core layer)
and the dust is discharged for burning. The
QuadradynTM can be used upstream or downstream of the dryer, with the latter design adding
to energy savings.
What is the customer’s advantage?
Paladin: The advantage shows, of course, in production costs: they are reduced by glue savings
and low maintenance; in addition, physical
properties improve as the dimensions of the
strands in the surface layer are not destroyed, but
maintained to the best possible extent, further
improving the appearance of the board.
Our machine is also suitable for retrofitting, as it
can easily replace an existing drum screen.
The advantages should convince the customer ...?
Paladin: In fact, they do. Since QuadradynTM has
been launched to the market, we have already
sold 9 plants. At the Huber plant in Broken Bow,
2 QuadradynsTM have been in operation since May
this year to the customer’s entire satisfaction.
We are very proud that we were able to contribute an impetus to the wood-processing
industry by developing QuadradynTM.
Mr. Paladin, thank you for the interview.

Evolution of short-cycle lamination presses
The success of wood-based materials in Europe is first and foremost the result of the tremendous popularity
of their surface treatments. As the papers, prints, foils and lacquers came to meet ever increasing requirements and the technology of the application was perfected, demand for surface-treated wood-based materials
grew in leaps and bounds.
by Klaus Zitzmann, Siempelkamp Maschinen & Anlagenbau GmbH & Co. KG
In 2002*, for example, the surfaces of approximately 5 billion m2 of wood-based materials in
Europe were treated. The lion's share – approximately 54% – was accounted for by the low
pressure laminating melamine (LPM) process
involving the direct application of duroplastic
resin films in short-cycle presses, and even more
growth is forecast for LPM over coming years.
Siempelkamp has now made further improvements to the technology of the short-cycle
press.
How did it start?
At the beginning of the development of shortcycle presses was the multi-opening press,
adapted from plywood production.
The glue chemistry meant that a pressing
process was required which started on cold hot
platens and then re-cooled the surfaces after a
heating up phase. This process was correspondingly time consuming and expensive in terms
of energy costs.
In the eighties, a new type of glue was developed
which eliminated the need for re-cooling and
considerably speeded up the process of polymerization.
This quantum leap led to the technology of the
modern-day short-cycle press, one which permits
large formats and pressing cycles of around
180 pressings per hour and more and therefore
offers a commercially attractive solution for
laminating the surfaces of wood-based materials
with duroplastic papers.
* Jaakko Pöyry: The Panel Surfacing Business 2003
In principle, these standard presses are all of the
same design, with two rows of crosswise cylinders and, subject to the length of the press, up
to six lengthwise cylinders providing the pressure
required on the press material.
To achieve the uniform distribution of pressure
required meant using hot platens of considerable
thickness.
However, hot platens of such thickness brought
with them the problem of relative thermal instability when fitted with only a single heating
channel system in the middle. These hot platens
suffered from “cupping” (transverse warping)
even during the heating up phase and did not
completely lose such instability during production
either.
To remedy this effect, the heating channels were
installed as close as possible to the product
surface and a counter-heating system was also
installed in the upper part of the hot platens.
This proved to be the solution for achieving
acceptable pressure and temperature distribution
in standard presses for short-cycle laminating.
Nevertheless, Siempelkamp technicians were
still not completely satisfied with the solution.
With so few pressure cylinders, surface quality
for different board formats was not always ideal
because of variations in pressure distribution.
This in turn was because the specific pressure
could not be fully controlled, despite precise
hydraulic pressure setting, a disadvantage which
was particularly apparent in the production of
laminate flooring and one which ultimately
prompted Siempelkamp to develop a new generation of short-cycle presses.
SIEMPELKAMP
The development of the multi-cylinder press
Development work started in 1999 with the
objective of improving pressure and temperature
distribution without any loss in the relative
stability of the hot platens under varying thermal
conditions.
Experience and experiments in the company's
own Research and Development Center,
supported by diverse computer simulations,
finally demonstrated that a press system with
more cylinders, of smaller diameters, provided
the optimum solution.
This is how the multi-cylinder press was born, a
press with up to four crosswise press cylinders
and up to fourteen rows of press cylinders.
This press was first constructed at the R&D
Center in Krefeld for test purposes only.
Tens of thousands of press operations were
performed in order to test the reliability of the
new design.
One of 2 MC-Presses at Shaw Industries, USA
Pressure and heat distribution were tested using
pressure-sensitive papers impregnated with
fast-reacting resin.
It was shown that the more uniform pressure
distribution permitted by the new press design
offered a definite advantage when producing
different product formats.
The technical advantages
Pressure distribution
The thinner hot platen, when compared to
standard presses, in combination with more
press cylinders, permits the pressure on the
product to be adjusted to meet specific
requirements.
All cylinders of the press are combined in
several groups of separately controllable pressure
systems. Consequently, the different control
systems can be used to provide the optimum
pressure distribution for the specific format of
product.
Temperature distribution
The results of a thermo-dynamic study carried
out in advance provided the basis for improvements to the geometry of the heating channels
in the hot platen to optimize the temperature
distribution on the surface of the product.
Diameter and position of the heating channel
system were optimised in order to achieve
a temperature distribution as uniform as
possible.
Thermal stability of the hot platens
The relationship between hot platen thickness
and heating channel diameter results in a
thermal balance in the hot platen during
production. This eliminates any need for a
counter heating system.
Lower pressure at the edges and corners of the
press material when the press is started is automatically compensated for by counteracting
pressure in the cylinders concerned.
This increased pressure is then automatically
returned to normal once production is running
and thermal compensation has been effected.
32 | 33

Customer advantages
Improved product quality
The new press promises a more uniform surface
quality across the entire press surface, even for
difficult decorative coverings, thanks to the optimized distribution of pressure and the productspecific setting capability provided by the separate hydraulic systems. Localized over-pressing
of the base boards or crushing of the edges is
eliminated.
Format flexibility
Frequent changes of format are no longer a
problem. Pressure and temperature distribution,
now also capable of individual adjustment,
guarantee first-rate surface quality.
Improved maintenance
A special cylinder design and a tried and tested
method of seal changing provide the guarantee
for low maintenance. The requirements of the
seals used on smaller pistons are lower because
there is less play between the piston and
guidance arrangement, resulting in longer
average service lives.
Subject to the maximum width and range of
formats and with a suitable working height of
approx. 1,500 – 2,200 mm, the need for a pit can
also be eliminated. This saves on capital expenditure and also offers advantages in terms of
cleaning and maintenance.
These advantages have already persuaded a
good number of customers. To date a total of 20
short-cycle press lines with the multi-cylinder
press at the core have been sold, 10 of them
between January and September 2004 alone.

NUKLEARTECHNIK
An order of strategic meaning
The modernization of the stud-tensioning machine in the French Nuclear Power Plant (NPP) Cattenom by Wenutec
By Horst-Werner Oehler, Wenutec GmbH

Reactor pressure vessel (RPV) schematic illustration
A: RPV cover, B: RPV studs and nuts, C: RPV lower part,
D: Fuel elements
In 1987 the first 1,300 Mwe nuclear power plant
unit started operation in the French city of
Cattenom. The units 2, 3 and 4 followed in
1988, 1991 and 1992.
From this time on the NPP has been supplying
electric energy generated with nuclear power
into the electricty net of the state-run energy
producer Electricité de France (EdF).
But for the multiple stud-tensioning machine
(French short form MSDG) delivered by Wenutec
the first usage on the reactor pressure vessel
(RPV) had already taken place 3 years before
starting the first NPP unit.
What is such a MSDG needed for?
In short, the reactor pressure vessels in the NPP
are opened and closed by using it in order to
replace the burnt down fuel rods by new ones in
time intervals of about 12 to 18 months and to
execute the tests which are prescribed by the
public authority.
As you can see in the picture on the left, the RPV
consists of the „lower part”, the so-called vessel,
and the „upper part“, the RPV cover.
Both parts are pressed against each other with
studs with dimensions between M150 and
M210 (of which up to 92 pieces are uniformly
distributed at the RPV circumference) and nuts so
that during the operation of the NPP no radioactivity can escape.
To open the reactor the studs with a length up to
2 m are stretched all at the same time hydraulically with forces of about 1,000 tons per stud
and pressures up to 3,000 bar to nearly 4 mm in
length (the expert calls that stud-tensioning) and
the nuts are loosened without big effort. After
this the studs are transported alone or together
with the stud tensioner to a storage position in
the reactor building. Then the removal of the
RPV cover from the lower part follows and the
RPV is open.
The MSDG delivered for the location Cattenom
was designed from 1982 on according to the
requests of the French customer EdF and represented at that time the state of the art of science
and technology in the area of automated studtensioning technique. By using this machine the
expenditure of time for opening resp. closing a
reactor could be reduced by more than 50%
compared to the traditional technique and a gain
in productivity of more 13,000 MW hours could
be made possible.
The machine was used more than 120 times in
its 20 years of operation, a timespan which is
characterized by a fast development in mechanical
engineering and in HP hydraulics, but especially
in automation technology.
Every technical progress has by nature the disadvantage of a more complicated spare parts
supply for older equipment.
The MSDG in Cattenom already execeeded this
point in time which could be proved easily from
the statistical breakdowns and the times of
repair.
34 | 35
Multiple stud-tensioning machine before modernization
EdF met this imperative all for action by ordering
from Wenutec the fundamental modernization
of the MSDG on August 5, 2004 with which
Wenutec had to prove a further reduction of the
time to a maximum of 4 hours when opening or
closing the RPV.
Despite of the late release of the order the
delivery of the new MSDG components will start
in time on November 15, 2004 in order to guarantee the fixed due-date of February 4, 2005.
The modernization concept for the MSDG in
Cattenom represents a variation of the MSDG
modernization which was completed to the full
satisfaction of EdF in the French 900 MWe NPP
Dampierre.
By receiving the order for Cattenom Wenutec is
the only MSDG manufacturer who can make
reference to plants in France which are in the NPP
power classes 900 and 1,300 MWe, France being
a market where orders for similar modernizations
in more than 40 NPP units at 14 locations will be
placed.

New press dimensions – A giant is born
Siempelkamp has always set the trend towards even larger and more efficient presses for the wood-based panel industry. Now a team
of technicians has developed the world’s largest OSB multi-daylight press with an annual capacity of 700,000 m3 (800 MMSF).

Obviously, dimensions, weights and transmitted
forces involved with such a large press are
considerable, indeed enormous. This is a
challenge for all our divisions concerned with the
design and engineering, the manufacturing, the

transport and the assembly of the press. New
paths must be trodden to master the enormous
forces.
An innovative concept has been elaborated,
basing on the proven and reliable standard press
designs for smaller presses, transmitting it to the
huge dimensions.
This concept convinced Slocan-LP in Richmond,
BC, Canada. Siempelkamp was awarded the
order for a 12-daylight press enabling a rawboard size of 12’ (3,66 m) x 34‘ (10,36 m), as tall
as an 8-storey building, having a weight of more
than 3,250 t (3,600 US tons).
Eight hydraulic press cylinders with a piston diameter of more than one meter (3.3 ft) each provide
a pressing force of 210,000 kN (42,600,000 lbf).
The press is designed as an upstroke press; its
frame consists of several elements. The individual
lateral stands are linked with the upper and
lower crossbeams, thus forming the press frame.
The elements are not welded, but put together
and fixed by bolts instead; this is to achieve a
higher fatigue strength.

The entire Siempelkamp know-how and the
synergies within the Siempelkamp group are
exhibited in the production of the heavy parts
like upper and lower press tables (described here
as an example). We were able to convince the
customer of the superior durability and the
reasonable price of a cast-iron design compared
to a welded design, considering that each press
table has the enormous dimensions of 4 m
(13 ft) x 11 m (36 ft) with a thickness of 1.8 m
(5.9 ft) and an as-cast weight of 215 t (237 US
tons).
This, of course, is a job for the Siempelkamp
Foundry Branch, Krefeld.
The great expertise of our hand-moulding
foundry at its Krefeld premises – which belongs
to the world’s elite for the manufacture of
castings of up to 300 t – turns out to be a real
competitive advantage.
On the basis of the design drawings elaborated
by the Siempelkamp Machinery Branch, the
Siempelkamp Foundry Branch prepared the
necessary mould pattern out of 260 m3 of
furan-bonded silica sand. This mould forms the
negative of the element to be cast. Any core

elements fixed inside the mould leave hollow
spaces after pouring. Although the upper and
lower press tables appear to be solid castings,
they have a filigree interior; this design is to reduce
the weight to a minimum while at the same time
to achieve highest dynamic resistance.
For the manufacture of the casting 236 t (260 US
tons) of iron are molten and poured into the
mould from four foundry ladles simultaneously.
760 t (838 US tons) weights are put on the
mould sunk in concrete pits; this is to fix the
mould and to master the buoyant forces
produced by pouring the molten iron into it.
The casting takes 3 weeks to cool off sufficiently
to enable its removal from the mould; in the
dressing room it is deflashed and fettled.
A short journey is to follow on a special truck to the
adjacent Siempelkamp Machinery Branch, were
the cast blank is subjected to its final treatment.
The table’s surface is machined with a portal
milling machine. This is to reduce the casting to
its nominal dimensions. Bores are drilled into the
10
7
casting to mount fastening elements to enable a
subsequent integration in the press system.
The hot platens for the press are also manufactured in the Krefeld factory. Each platen has
a gross size of 4,105 mm x 10,730 mm (13.5 ft
x 35.2 ft) and a weight of 70 t (77 US tons). The
platens’ surfaces are machined with a portal
milling machine to almost nominal dimensions of
the hot platen.
On a special deep-hole drilling machine the
heating channels are drilled into the solid material.
120 years ago Gerhard Siempelkamp founded our
company on the basis of precisely this know-how.
About 700 m of drills are implemented in each
hot platen to form the channels for the heating
medium to circulate and to heat up the platens
to 220 – 240°C (428 – 464 F).
The Slocan press is designed with 12 daylights,
which implies that 13 of this XXL-hot platens
have to be machined and drilled.
Another technical highlight is the manufacture
of press cylinders. The cylinder segments are
11
8
9
made of hot-rolled steel; in a first step they are
machined, then welded and stress-relieved;
cylinder top and base are made of forged steel.
In another process they are turned on a lathe;
subsequently diverse bores are drilled.
The cylinders are fitted with liners, which have to
be cooled in liquid nitrogen to -195 °C (-319 F)
to shrink them. The liners thus cooled are
inserted in the cylinders; while expanding during
their “heating up” to ambient temperature they
properly fix inside the cylinder.
The operation of the 12-daylight press requires
an adequately dimensioned hydraulic system.
This hydraulic system delivers the hydraulic
pressure of 320 bar to generate the specific
pressure required for pressing.
An advantage of the new design principle of
the press is the relatively easy handling during
shipment and transport of the individual parts as
well as a rapid construction at the production site
in Forth St. John, BC, Canada. The first heavypart shipment is scheduled for the end of
October 2004.

All employees at the Krefeld base are doing their
best; all synergies are exploited and new paths
have been trodden to enable the birth of the
giant.
We are very proud of this achievement.
The new press will be the core element of a line
with a combined belt/screen transport system,
already sold 16 times by Siempelkamp to North
America.
To enable a gentle strand drying, the line also
includes three large rotary dryers delivered
by Siempelkamp’s 100%-subsidiary, Büttner.
Siempelkamp’s associated company PAL will
15
supply the newly developed QuadradynTM
strand classifier, which have rendered excellent
performance at another North American OSBfactory. The Siempelkamp CombiLine system will
also include six strand mat formers of the proven
and acknowledged design. Siempelkamp Handling Systeme (SHS) will supply the complete
finishing line equipment including stacking
system, a fully automatic saw line, a high-speed
tongue-and-groove line and two packing lines.
Siempelkamp Canaca, Cambridge, ON will be
responsible for the automation and control of
the CombiLine and the complete board finishing
system.

Start of assembly is scheduled for December
2004 with OSB-production to begin in
September 2005. The plant is designed for an
output of 2,020 m3/day of OSB with a thickness
between 6 and 32 mm (1/4” – 11/4”).
An output like that can only be rendered by a
robust and extremely dependable press.
Finite Element Methods (FEM) – one of the engineering tools
used for the Slocan project
The FE methods serve to solve complex questions in the field of technology and natural science. In this process, the problem is broken down into small units which
can be described precisely. Loads and stresses, crash simulation, forming processes, flow analyses or thermal conductivity can thus be clarified.
By Klaus Schürmann, Siempelkamp Maschinen- und Anlagenbau GmbH & Co. KG
For the design work of the 12 ft-Slocan press
we also based on the FEM, determining any
deformation, load and stresses of the press
components (frames, cylinders, beams) as well as
pressure distribution on the product surfaces.
Especially in the case of Slocan, where immense
forces and component dimensions are required,
the numerical simulation of such components is
indispensable.
The geometric description of the components
is passed from the 3D CAD-system directly into
the computation unit. These data are completed
with the loads and boundary conditions; the
models thus generated are computed and
evaluated.
This is to trace any weak points and to eliminate
them by geometric variants.
Spectacular developments in the field of computation enable the analysis of very complex
structures. Today we can represent the entire
press system while just a couple of years ago, it
was only possible to simulate individual components.
The transfer of the 3D data within the production process accelerates the optimisation.
A coherent process is developing from the design
to the computation up to the project preparation
in the foundry.
The geometry within a foundry pattern can be
widely influenced, thus enabling the generation
of homogeneous stress and material distribution
within the component structure. The different
colours indicate the different stress levels inside
the structure.
Once a model has been computed and
elaborated, it is possible to infer all stresses,
deformations, reaction forces and pressure
distributions, in a word, all interactions with

Siempelkamp Foundry expands capacity to meet production needs
Installation of additional sand reclaiming system and core manufacturing facility
Right next to Siempelkamp’s molding shop an
additional sand reclaiming system and a new
core manufacturing facility started operating in
August 2004.
The core manufacturing facility is equipped with
sand mixers for the production of large-sized
cores. By relocating the former core manufacturing facility to a new production hall Siempelkamp was able to expand its molding shop. The
restructuring will result in a production increase
of 7% which can be translated into 4409 US tons
of net production.
The new sand reclaiming system, including a
flask shake-out grid and new sand silos, supports
the existing sand reclaiming systems and is
necessary for the increased production.
The existing sand reclaiming systems achieved
capacities between 92% and 95%. The fluctuation differences mainly resulted from the diverse
range of products. For many large-sized castings
the capacity was too small to recycle the large
amounts of used sand. The reclaiming process
of used sand is now positively influenced by
additional buffer sections and storage possibilities for flasks. The new production unit consists
of three sand silos with a capacity of 220 US tons
each and a mechanical reclaiming capacity of
661 US tons per day.
Left: The hall wall is being closed,
Right: The gantry crane in the core moulding bay

The new core manufacturing facility now operates on an area of 900 square meters. The sand
reclaiming system was extended to 700 square
meters. The building and the systems installation
were completed within 4.5 months.
the interfacing equipment (foundations, piping,
etc.).
The material interfaces between the individual
components within the entire complex are also
indicated. This is to solve any questions concerning e.g. necessary screw pre-tensioning.

In addition to the metal press components, the
model of the press also takes into account the
characteristics of the wood furnish to be pressed.
It is thus possible to project the product geometry to be expected for every daylight.
Conclusion:

The FEM is a most efficient tool, without which
we were not able to design our components to
the state of the art.
