President Message
It is a matter of great satisfaction for me that Pakistan Foundry Association has
successfully organized the 3rd International Foundry Congress & Exhibition at
Pearl Continental Hotel Lahore on December 01 & 02, 2010. It was largely
attended by around 3000 foundrymen, Engineers, Technical Managers,
Exhibitors, Buyers, Sellers and Students etc from all walks of Industrial Sector in
Pakistan. This year we had an ever increased participation by local & overseas all
those who are concerned with the Foundry Industry.
The participation from foreign countries i.e. Turkey, India, China, UK, Czech
Republic etc was encouraging for us. Few important visitors Mr. Basar
Oztopcular - Cukurova Kimya End. A.S, Turkey, Mr. Chavan Pruthviraj Ravindra,
Mr. Shinde Sunil Shivajirao, Mr. Singh Subodh Rajan, Mr. Vinay kumar luthra Gargi Huttenes-Albertus (Pvt) Ltd -India, Mr. Vikas - Director Marketing and Mr.
Ashok Sharma -Engineer Megatherm-India and many more. I highly acknowledge their participation as they
travelled all the way for this event.
Since our first IFCE 2006 the PFA has gained the attention of the Foundry Industry globally and now IFCE is
becoming one of the most important event in the region. Special added feature this year was more focused
platform for local & International sourcing. A very encouraging response from the major casting users like Defense,
Automobile, Sugar, Fertilizer, Cement, Paper, Power and Engineering Sector and provided good opportunity for the
foundry men to interact with potential buyers of castings.
The major objective of the Pakistan Foundry Association (PFA) is to support the progress & development of
Foundries in Pakistan by improving skills and up-grading technology. After 3rd IFCE 2010 some positive response
has been seen by the government. In this regard National Productivity Organization - Ministry of Industries,
Islamabad provided the services of a Foundry Expert Mr. Ram Chandra Narayan Bhome to visit certain foundries in
Lahore for the improvement of this industry. His observations and technical advice for improving quality,
productivity and cast reduction will provide positive result in the growth of light engineering sectors particularly
SMEs.
In Pakistan, Foundry Industry's basic problem is scarcity of skilled man-power, which is resulting in low productivity
and quality. PFA and TEVTA (Technical Education & Vocational Training Authority) Lahore, Govt. of Punjab is
developing a training centre for un-skilled labour on the direction of Mian Shahbaz Sharif -Chief Minister Punjab.
Mr. Saeed A. Alvi-Chairman TEVTA has assured his full possible support and would be flexible to any model of
cooperation with PFA as long as the requirement of Industry exists.
I once again thank all those concerned with the foundry industry who participated in the
Sikandar Mustafa Khan
3rd IFCE and assure a dynamic business platform for their growth in future.

44th Census of World
Casting Production
The global casting market experienced a marked contraction
in 2009, with overall shipments decreasing 14% from 2008.
A MODERN CASTING Staff Report
Worldwide casting shipments in 2009 fell to 80,343,048 tons, down 14% from 2008, according to this year’s
MODERN CASTING Census of World Casting Production. Of the 34 countries participating in the production survey
this year, only five reported growth—China, India, Korea, Portugal and South Africa. The average percentage
decrease in shipments for the remaining countries with declining production was 30%. As a result, production per
plant decreased, as well. Germany still has the most production per plant, but it fell from 9,639 tons per metalcasting
company in 2008 to 6,481 tons in 2009.
China’s production improved from 1,117 tons to 1,357 tons per plant as shipment volume increased and the number
of casting facilities decreased. Seven of the top-10 casting-producing nations shifted up or down in the rankings in
2009, reflecting the fluctuating markets during the recession. Brazil, which had been one of two top-10 countries to
show growth in 2008, experienced a 31.5% decrease in shipments from 2008 to 2009, the biggest drop of any top-10
nation during that time period. India was the fastest growing top-10 nation, increasing its casting tonnage by 9%. The
top 10 nations produced a total of 70,476,338 tons, 88% of the global total.
The year 2009 marked the fourth year in a row the U.S. has reported a reduction of casting volume. It was the first
year it has been surpassed in production (by 35,000 tons) by India, which became the second-largest casting
producer by volume. The data reported in the 44th Census of World Casting Production is supplied by each nation’s
metalcasting association or similar representative. Countries that did not participate this year were Denmark, The
Netherlands and Thailand. These countries remain listed according to the last year they participated. New to the list
are Bosnia and Herzegovina, Mongolia and Serbia. MC
China: 1,357
India: 1,618
Production Per Plant
Top 10 Casting Countries
The average production per metalcasting plant for the top10 nations decreased across the board, likely due to plants
operating at lower capacity during the 2009 recession. China
and Korea, which showed increases in casting shipments
from 2008 to 2009, improved their productivity.

New to the List
A few new countries have been added to this year’s census of casting producers and another has been updated after
seven years of incomplete data. Ukraine: Before this year, the most recent production data from Ukraine dated to
2002, when the country was producing 974,170 tons of castings a year. Not much has changed. The Foundry
Association of Ukraine reports the country produced about 1 million tons of castings in 2009. Ferrous casting makes
up the lion’s share of production (95.5%), but nonferrous casting has improved 42.9% since 2002. Serbia: For many
years, this country has been in turmoil, with much of the casting activity shut down or severely hampered.
10
From 1990 through 1999, its economy was cut in half. Since then, Serbia has been making up ground. In 2008, the
Serbian Foundrymen Society was formed. The country’s casting industry is 81% ferrous and 19% nonferrous by
tonnage produced. Production per plant is 2,345 tons. Mongolia: More than two-thirds of all of Mongolia’s exports
go to China, its neighbor to the south. Its largest casting market is steel, which makes up 81.6% of total production.
With the exception of a few nations, the global casting industry reported a dip in production in 2009. But some
countries fared worse than others.
Russia: From 2007 to 2009, Russia’s production decreased by 46.2%, from 7.8 million tons to 4.2 million tons. The
third largest casting producing nation in 2007, Russia has since fallen behind India and Japan. It saw a reduction of
300 metalcasting facilities in 2009.
20
Finland: In one year, Finland’s casting production was
cut in half, from 152,888 tons to 75,741 tons. Casting
production value decreased 46% to $350 million. Zero
metalcasting facilities closed, according to the European
Foundry Assocation, but employment in the industry
constricted by 700— 15.7% of the workforce.

Gray Iron vs. Ductile Iron
Globally, 65% of iron castings
produced are in gray iron, compared
to 35% produced in ductile
iron. But this type of disparity is not
present in every country. Among the
top five casting
nations, the U.S. produces more
ductile iron castings than gray iron,
while Russia and Japan
show closer gaps between the two
materials than do China and India.

the needs of our foundry members industries for
Technical Guidance, Efficiency Enhancements,
Process Engineering and Cast control.
Mr. Ram Chandra visited 12 foundries in Lahore and
made certain observations in different foundries and
suggested remedial actions on the spot. He spent
sufficient time for their guidance in each foundry as
desired by the foundry members.
According to PFA Plan, Mr. Ram Chandra Narayan
Bhome had to visit foundries in Gujranwala and
Faisalabad also but due to limited visa facility he could
visit foundries in Lahore only.
A seminar for the training of technical managers was
organized for two days in PITAC – Lahore. It was a joint
venture of NPO & PITAC on the foundry production
system.
The purpose of this workshop was to create
awareness and understanding to improve and
enhance production efficiency according to his

development of any country.
•
There are 2 types of Casting:
i- Ferrous
ii- Non-Ferrous
•
According to the 43rd census of world casting production 2008:
Total production of the world is 93.4 million metric ton

One major question that arises from this overview is:
“ If countries like India and China can prosper so much then why can not a country (Pakistan) enriched with ample
resources flourish? “
Few of the problems facing India and China are similar to that of Pakistan:
- India for example is currently facing electricity crises but they have intelligently manage it to cope with
their production targets. Why not Pakistan follow the same steps????
China for example, with the help of coal gasification and washing plants, has successfully used their coal
16
reserves for power generation. Then why can not Pakistan use these cheap plants for upgrading the available coal
reserves for power generation?????
- Thar coal reserves are the largest coal reserves in the world. The only problem is that coal need washing
(sulphur 6 -10 %).Otherwise rest of the specifications e.g. caloric value, ash content and fixed carbon etc
are within limit.
Comparison of Pakistan with other Asian countries
Comparison of Pakistan and China with respect to respective countries' prices and potential in casting.
Comparison of Pakistan and India with respect to the countries potential and resources availability.
Comparison of Pakistan with China
According to year 2008 figures:
China:
- Population: 1.3 Billions
- Production: 33.5 Million tons
Pakistan:
- Population: 0.18 Billions
- Production: 0.35 Million tons
Analysis of the figures:
The population of China is almost 7.2 times more than that of Pakistan. Following this the production of Pakistan
should be 4.65 million tons which at present is only 0.35 million tons. This means that Pakistan's production is 4.3
million tons less than the expected value.
•
Comparison of prices :
•
Price break up of a standard firm casting in Pakistan
•
Total cost on raw material (less foundry return) per kg
•
Total cost of other materials per kg
•
Total cost of fuel and power per kg
•
Total cost of molding, melting, all other felting, painting, short blasting etc per kg
•
Bank Charges per kg
•
Non productive expenses
•
Total COST PRICE per kg
•
With a profit margin of 10% - SELLING PRICE
Whereas , casting prices in China vary within the following range :
Rs 104 ≒Price per kg ≒Rs 130
Where Rs 104 refers to a typical low cost firm's price and 130 refers to a typical high
= Rs 47.14
= Rs 12.65
= Rs 14.25
= Rs. 8.41
= Rs 1.25
= Rs 6
= Rs 89.7
= Rs 98.7
cost firm's price.
Comparison of prices clearly shows that Pakistan has a price edge over China. Likely reasons for such a price
edge can be excess supply of cheap labor, availability of natural resources and likewise other related factors.
However, comparing the production scale of Pakistan with China will be inappropriate given the size of the
economies and development scale. On the other hand comparison with India will make more sense as Pakistan
shares a lot of common features with this neighboring country.
Comparison of Pakistan with India
•
According to Modern Casting December 2009:
“India's metal casting industry is poised to become one of the top-three casting producing nations in the
world. The key is establishing the infrastructure to support it.”
17
•
The growth in casting production of India is remarkable since year 2002. India benefits from:
i) low labor costs,
ii) large population with a strong domestic demand,
iii) financially strong companies with revenues to invest in metal casting.
iv) Furthermore India's economic environment is suitable for metal casting.
v) Construction costs for new casting facilities, as well as time to complete construction and
permitting are low.
vi) Health and safety compliance requirements for molding binders are nearly non-existent and tooling
costs are significantly lower than in developed countries.
• Hurdles faced by india:
i) Even though tooling costs are lower but tooling quality is still lagging
ii) lack of sufficient infrastructure
iii) consumable costs are higher than developed countries
iv) energy supply problems, especially a reliable supply of electricity
v) attracting and maintaining an enthusiastic, younger force is a challenge in India.
•
Hence we can see that most of the advantages enjoyed by India as well as problems faced by the Indian
economy are quite similar to our Pakistani economy. Therefore comparing our economy with the Indian
economy and setting it as our benchmark will be wiser rather than comparing with economies like China.
•
According to year 2008 figures:
India:
- Population: 1.14 Billions
- Production: 6.8 Million Tons
Pakistan:
- Population: 0.18 Billions
- Production: 0.35 Million Tons
•
Analysis of the figures:
The population of India is almost 6.3 times Pakistan's population. Following that Pakistan's production
should be 1.07 Million Tons. At present it is 0.35 million tons which is 0.73 million tons less than the
expected value.
•
As mentioned earlier too, Pakistan's casting is cheaper than both India and China. Hence Pakistan should
make efforts to utilize its potential to the maximum and increase its production. Increasing production by
0.73 million tons might not currently be possible due to the energy and policy constraints in Pakistan but a
step forward will not hurt the country's development plan.
Feasibility of achieving targeted production ( in comparison with India)
•
•
•
•
•
•
•
18
Assume the target is to increase casting production by 0.73 million ton
1 ton = 1000 kg
Cost price = Rs 89.7/kg
Selling Price = Rs Rs 98.7/kg
Gross Profit = Rs 9/kg
Taxes and other miscellaneous charges = Rs 3/kg
Net Profit = Rs 6/kg
•
Given the net profit per kg = Rs 6 , if Pakistan increases its production by 0.73 million tons. The additional
profit earned by Pakistan will be :
:
Ð = 0.73 million tons x 6000/ton
= Rs 4380 million ( minimum profit)
Graph ( price & profit) - Feasibility of achieving targeted production ( in comparison with India)
Feasibility of achieving targeted production ( in comparison with India)
•
Major Constraints to achieve the targeted production :
1- Utility expenses
2- High fluctuation in the price of imported raw material
•
Remedies:
1- Government should invest in exploring iron ore.
2- Use of wind energy and hydro energy etc in power generation
3- Coal gasification and washing plants for power generation
4- Proper government plan and cooperation with foundry engineering
•
Current Scenario :
None of the remedies suggested are currently being implemented but through asuccessfulimplementation
of these remedies, an additional target of 0.73 million ton ( casting production) can be achieved in next
couple of years.
•
Potential gains from additional Production of 0.73 million tons in future:
- Figure of 0.73 million tons is not a huge threat to India or China given their casting
production, but Pakistan can gain a lot through this additional production
- Through this additional production Pakistan can not only meet the additional demand of
domestic economy ( currently imported) but can even export the surplus production.
19
Standard Model
•
•
•
•
•
•
•
•
Assume a plant has a yearly production = 12000 tons
Net Profit/ ton (calculated before) = 6000/ton
Total Net Yearly Profit = (12000 x 6000) = Rs 72 millions
Assume Fixed Cost investment = 40 million (Land) + 100 million (machinery) + 30 million ( utilities) = Rs 200
millions
Assume working capital = Rs 100 million
Assume interest payment = Rs 60 million
Total investment = Rs 360 millions
Pay back Period = (Total Investment) / (Total net yearly profit)
Therefore payback period with casting production = 12000 ton and minimum profit margin = 6000/ton will
be = Rs 280m / Rs 84m = 5 years.

casting products at a high price price per ton will increase profits will increase payback period will decrease !
Benefits from exporting to foreign market
Comparative advantage through low relative price as compared to India and China attracting wider consumer
baseCheap product in the international market due to depreciation of the Pakistani currency. e.g. exchange rate of
Pakistan with china increased from 1Yuan = Rs 7.8 (year 2007) to 1 Yuan = Rs 13 (year 2010)
·
Inflow of technology
·
Increase consumer base through international market
·
Inflow of Foreign currency increase foreign reserves
·
Positive effect on the Balance of payment
Export demand increases Total domestic production increases Average Cost per unit will fall through Economies of
scale Net profit/ton increases!
Export demand increases Total domestic production increases domestic employment increases disposable
income increases Aggregate demand for goods and services will increase Real GDP increase Economic growth and
overall standard of living of the economy will increase!

Conclusion
It is fair to conclude that Pakistan which is rich in factors of production e.g. land , labour , natural resources and
entrepreneur skills , should efficiently utilize these resources to meet at least reasonable future targets.
In the coming future major production is shifting from USA and European countries to China and India. Then why not
Pakistan (which is the part of the same subcontinent) increases its % production and be one of the prominent
producers supplying to the foreign markets?????

Pakistan is a home of several bright people. I believe that we have radiant minds sitting amongst us today
that can not only help in the nourishment of the industry, they can also enrich our minds with their brilliant ideas.
This will help country develop successful future strategies and their implementation will help country efficiently
compete in the international market at all standards.
I also believe that the youth of the nation has a lot to offer. A concoction of our experiences with their minds can
definitely prove to be beneficial for the burgeon of the casting industry.

Problem-Shrinkage:
Shrinkage occurred inside thick portion of
casting
Problem-Shrinkage:
Simulation done with little improvement
Better results but Pattern also needed modification
As suggested Chill was also tried but production
rate was low due to placing of chill
22
Problem-Shrinkage:
During this period due to ro ugh surface finish in
the hole the machining section was complaining.
Problem-Shrinkage:
We were already working on the Die of Core
for “Shell Core Sand”. When started using Shell
Core it was observed that the riser had much
more shrinkage at the top then the usual practice.
Pieces were sectioned to see if it has contributed
to shrinkage. Surprisingly the shrinkage was
eliminated.
Cross-Section of Arm Hyd.
Lift Ram with no Shrinkage
It gave us motivation & encouragement
to do more research on Shell Core Sand.
More samples were casted using Shell
Cores and their cross-section exposed
elimination of shrinkage problem.
Comparison of Cores
CO2 & Shell Cores
Coclusion
Sodium Silicate Cores exhibit Endothermic Reaction after pouring.
Shell Cores show Exothermic Reaction when contact with hot metal.
Shell Core Sand, beside shrinkage elimination, are very easy to remove & give good surface finish.
The Exothermic Reaction of Resin Coated Sand Cores, when contact with hot metal, helps keeping the
metal flowing from riser into the casting and hence eliminates shrinkage.

Vacuum hardening & nitriding furnaces
Vacuum Hardening Furnace
Introduction:
Vacuum Heat treatment is one of the modern heat treatment technologies which helps to determine the
right process & right cycle to meet the metallurgical requirements in hardening and nitriding of dies &
moulds through precise temperature and atmospheric control. Customers specifications are achieved
with minimal distortion and bright, scale free results in the finished products.
Advantage of vacuum heat treatment process:
Heating metals to high temperatures normally causes rapid oxidation, which is undesirable. Vacuum heat treatment
removes the oxygen and prevents this from happening.
The need for precise control of temperature and time, as well as the process environmental chemistry, has led to the
application of computerized control systems for most types of modern vacuum furnaces. Following are some of the
advantages of this process:
·
·
·
·
·
·
·
·
·
·
No decarburization
No oxidation of components – bright surfaces
High temperature uniformity – low distortion
Full automation of heat treatment process
Environment friendly
No heat radiation to atmosphere
Low contamination of the product by oxygen and other gases
Quick cooling (quenching) of product
Computer control to ensure batch to batch consistency
Precise control of case depth, microstructure & hardness
Processes Facility:
The processes which can be carried out by vacuum heat treatment furnaces are:
·
Annealing,
·
Stress relieving,
24
·
Hardening,
·
Tempering
·
Nitriding
Different ranges of temperatures for
carrying out above processes are
carefully determined with the help of
TTT and Iron-Carbon Diagrams as in
figure number 3 and 4.
Tool Steels suitable for heat treatment in vacuum furnaces:
· Hot Work Tool Steels like H-11 & H-13
· Cold Work Tool Steel Like D2 & D3
· Moly High Speed Steels
Vacuum Heat Treatment Process:
Heat treatment of hot & cold work tool steels in vacuum furnaces is today state of the art technology with
fully automatic process which employs latest HMI system (human machine interface).All parameters like
temperature of the surface and core of heating stock, pressure levels of nitrogen/ammonia gas and
information on various levels of vacuum etc are displayed continuously on furnaces screen and can be
reset as per behavior of the charge components.
Like other processes, this process also involves heating, holding & cooling.
However in other processes during heating up & cooling, temperature
difference occurs in surface & core of the component. This temperature
difference in other processes can not be avoided and is reason for
component distortion due to residual stresses. This component distortion
can be reduced by CONTROLLED step by step heating and cooling in vacuum
heat treatment furnaces. Desired microstructure & ultimate hardness is
achieved by a predetermined programme of phase transformation which is
the specialty of vacuum heat treatment process.
Figure: 5 HMI System Screens
Normally oxidation occurs on the part's surface when exposed to the atmosphere (air). This results in
costly and time-consuming post treatments. Therefore, heat treatment in vacuum is conducted in an
oxygen-free atmosphere. In addition to the use of high-purity protective gases, vacuum allows the best
protection against oxidation.
Due to limited time, here I shall discuss only the hardening and nitriding processes for dies and molds
made out of H-13 steel.
Hardening Process:
Dies/Molds or other tool steel components are loaded on top of a tray made for this purpose in furnaces
along with a test sample. After closing the door the atmospheric pressure/air in the chamber is removed
automatically by using vacuum pumps.

As the required vacuum level (10-3mbar) is achieved, the selected reciepe/programme is run to meet required
hardening process which contains fallowing steps.
(a)Nitrogen Purging:
During purging segment duly evacuated furnace chamber is backfilled with inert gas to an ambient pressure. This is
done to provide better quality of the furnace atmosphere and a higher vacuum level for removing any trace of air or
humidity in the
furnace chamber.
(b) 1st Stage / Gas Heating:
The temperature of furnace is raised by employing a convection fan to 650°C while keeping the pressure of inert gas
at two bars (max).
(c)Vacuum Heating:
Under this step the temperature of furnace is further raised to 850°C under vacuum 10-1mbar.
(d) Partial Pressure Heating:
This is the last step of continues heating during which temperature of the furnace is raised to about 10300C under
controlled partial pressure of inert gas. Soaking time of 30 minutes for each inch thickness of components is allowed
now to bring them in austenitic range (hardening temperature).
(e) High Speed Cooling:
This is a quenching process but the quenching media is now nitrogen gas which is sprayed on heated stock at a
pressure 5 bars to obtain best martensitic structure.
Recipe/programme of H-13
Tempering Process:
The process of tempering is best carried out in these furnaces to:
(1) Remove thermal stresses induced in the stock due to quenching.
(2) Convert any retained austenite into fully martensitic structure.
To achieve above results the tempered stock is again heated to about
5700C under an environment of nitrogen. Proper soaking time is
allowed as per thickness of the material and then slow speed cooling
26
Trends of H-13
is done with nitrogen at 2 bars. Hardness in the range of 44-48 HRC can be achieved by following reciepe. To get still
better structure, 2nd cycle of tempering is also carried out as per figure number 12.
Vacuum Nitriding process
This is a special case hardening process that depends on the absorption of nitrogen into steel components. All sort of
machining, stress relieving, as well as hardening & tempering processes are normally carried out before nitriding.
The parts are heated in a vacuum chamber through which ammonia gas is allowed to pass. The Ammonia is split at
4900C into hydrogen and nitrogen and the atomic nitrogen creates bonds with nitriding forming elements
penetrating the surface to form nitrides.
Nitriding steel offers many advantages: a much higher surface hardness is obtainable when compared with case
hardening steels; they are extremely resistant to abrasion and have high fatigue strength.
Reciepe/programme Nitriding
Trends H-13 Nitriding
In nitriding process, same steps are taken till the 1st stage i.e. (gas heating), which were adapted while doing
hardening of components.
Later on further processing is carried out as explained now:
(a)Ammonia Purging:
Purging with ammonia gas which dissociates at 4900C.
(b) Stage 1 & Stage 2 Nitriding:
During this segment nitriding procedure is carried out in stages. Stage one is carried out at temperature of about
5100C in which nitrogen is diffused at low rate of diffusion, in order to avoid formation of white layer, which is brittle.
Stage 2 nitriding is carried out for long term diffusion at a temperature higher than stage one as it diffuses more
nitrogen into components. As a result of above treatment, a nitrided layer of 0.1mm to 0.15mm thick is formed with
HRC in the range of about 65-67..
Hardened & Nitrided Jobs:
(c) Nitrogen Purging:
After completing the nitriding process, nitrogen purging is carried out and at
the same time temperature is brought down from 5500C to 4500C.
(d) Blower Cooling:
Cooling in nitrogen gas with external gas blower at pressure of 0.05 bars.
(e) End of Cycle:
End of nitriding cycle and readiness for unloading.
