AMUT AT PLAST 2012 EXHIBITION IN MILAN

AMUT AT PLAST 2012 EXHIBITION IN MILAN
Thermoforming.
The highly competitive market of the disposable items requires a
particular care from the side of the Manufacturer of the thermoforming machines, who must
be able to let his technical knowledge available at Customer’s disposal. This has always been
the philosophy of AMUT thermoforming department which allows the continuous innovation of
the machine product.
AtPlast 2012Exhibition, AMUT shows the evolution of the high speed automatic
thermoforming machine series FFG, forming and steel rule die cutting technology.
The FFG820 ADV machine will be in operation with a mould dimension of 820x620 mm
(dimensions before chain spacing). Modular frame to minimise the overall dimensions during
transportation and standardize the production. Compressed air and/or vacuumforming. Toggle
system for platens stroke, with planetary roller screws, proved guarantee of resistance and
duration under cutting conditions of the strongest materials at high speeds, both in the forming
and in the cutting stations with an installed force of 60 Tons. All kinematics and accessory
equipment are driven by brushless motors. All the presses are 4-column type, the structure
and the frame have all the characteristics of stability and rigidity of AMUT’s projects, together
with the high performances in terms of cycles/minute.
Great attention has been given by AMUT also to flexibility and user-friendliness. And that’s
why there are quick change of the moulds in all the stations, direct connectionsto the utilities
on the mould platens of the forming station and the electric hoist. All that as an integration of
the new easy and quick mould change systems.
AMUT has recently supplied and started a very high production in-line plant of extrusion and
thermoforming based on a similar thermoforming unit, four-stations, type FFG4 820 ADV for
the thermoforming of items for flower-nursery market.
It is a machine suitable for the production of deep items up to 200 mm, which uses the
technology of the additional hole-punching station to make the holes on the bottom of the
flowerpots and the automatic stacking based on 3-axis robot, fourth generation stacker. This
last one is a success solution that highly makes easy the problem of the finished items
handling, mainly in case of round-shape flowerpots. The end-line is equipped with a
computerized collection and conveying system in pre-set piles of flowerpots that must be only
packed by the operator.
The plant, unique in its own way, is upstream equipped with a co-extrusion group for the
production and the in-line feeding of PP foil. It is a perfect example of the integration of
AMUT’s experience in extrusion and thermoforming.
The extrusion group is based on two AMUT single screw extruders, 2-layer feed block and flat
die expressly designed and manufactured by AMUT for the production of bi-colour foil, special
compact calender unit for vertical high efficiency in-line applications.
Customer’s choice, to lean on AMUT in developing the new production process based on
thermoforming and that previously was based on injection, has been successful in terms of
quality, weight reduction and productivity increase. The planning and the manufacturing of
each plant component have been made inside AMUT, Company unique in its own way, that
has the broad-spectrum technology, embracing extrusion, thermoforming, packing of the final
product.

Extrusion.The latest technologies for WPC (Wood Plastic Composites). The products
obtained by WPC have wood like appearance and they do not requireany further
machining, they are weatherproof, waterproof and suitable for indoor and outdoor
applications, where the common wood could not be suitable.
“EASY WOOD” is the system proposed by AMUT and includes the supply of “Know
How”and complete lines from 300 up to 1000 kg/h and over. It offers custom-built solutions
for the use of each type of vegetable fibers, from wooden scraps to production scraps of
natural fibers, such as sugar cane, rice hull, etc.
AMUT plant.Direct extrusion line, without pre-mixing of any materials and additives with
quantity of vegetable fibersup to 80%, on Polyolefin base (HDPE e PP), while with PVC
the quantity is approx. 50%.
The fibers of natural origin that can be used are different such as: wood fibers coming from
different sources (feer, beech, etc.), rice hull, sugar cane...
The extrusion line is equipped with a counter-rotating twin screw extruder and with a single
screw extruder. The counter-rotating twin screw extruder is the ideal machine to process
very viscous compounds, such as WPC, with high percentage of vegetable fibers. Thanks
to the screws low revolution speeds and high torque, it is possible to extrude at high
pressure values and reduce cutting actions keeping the extruded melt temperature low so
as to prevent the degradation of the vegetable components.

It will be also exhibited a single screw extruder EA75 with barrel L:D=35:1. According to
the geometry of the screw and the different configuration of the barrel (whose initial part
can be cooled or thermo-regulated), it can be used in all the sectors with outputs up to 750
kg/h. It is available with barrel L:D up to 40:1 and widely used in pipes sector in general
and for technological pipes made of special materials.
All along in the vanguard in the supply of lines for medical application, where besides the
precision it is absolutely necessary to grant the product sterility, AMUT is always more
specializing in the automotive sector. Just for this sector, besides the PA multilayer lines,
AMUT has developed and supplied lines for the production of pipes in
polyvinyldenfluoride (PVDF) and polyoxymethylene (POM).
Such materials are particularly suitable to be used in the automotive sector for their
solidity, resistance and dimensional stability, together with the low friction coefficient which
give very good sliding features and wear resistance to the small pipes. Besides they are
resistant to the high temperatures and to oxidant agentattack.
The pipes produced on these lines must respect very strict parametersof dimension and of
ovalization, keeping constant a rigorous stability of process for all the production. For this
reason, AMUT pipe extrusion lines for automotive industry are equipped with diameter and
thickness very accurate measuring and control systems and, thanks to the extruder
stability, they grant a constant production without oscillations.
The lines produced by AMUT for the European market are equipped with special
calibration and cooling troughs, diameter and thickness control systems, haul-off units,
cutting units and automatic coilers and are also completed with high speed cutter and a
belt conveyor, with pneumatic selection of the finished product, able to produce very short
parts of pipes.
