Flat Die Plastic Extrusion
Microcontroller improves accuracy and safety and reduces material waste
|Industrial sector (PRODCOM code)
The company EMO situated in Micheldorf, Austria, was founded
in 1996 and is involved in the design and manufacture of one- and multi-channel
dies with and without restrictor bars for:
(compact, free and integral foaming) and for back-press technology with
adjustable outlet width and cutting device.
The world-wide market for EMO's dies is steadily increasing since more
and more products are being made of plastic films or sheets, (e.g. drinking-vessels,
back-pressing of materials in the automotive industry etc.). Currently
the main focus is on sheet dies for PVC compact and foaming sheets as
well as film dies for equipment for making polyethylene and polypropylene
ribbons. EMO's products are mainly used in the synthetic material industry
and are distributed through OEM manufactures or are sold directly to the
The company has 13 employees none of whom has any experience of electronics
development. To this day EMO only produced manually adjustable dies. So
far, there was no electronic development carried out in the company.
By carrying out the design of a microcontroller, market requirements,
which demand strict tolerances due to the high cost of raw material, can
be met. Additionally, by controlling the thickness electronically the
finished material can be processed faster increasing throughput.
The product to be improved is a flat die for film and sheet extrusion.
The outlet of the die specifies the thickness of the extruded product.
Currently the extrusion gap is controlled through manually adjustable
push and pull screws which have no electronics part.
In the market for thin film extrusion exclusively automatically controlled
flat dies are used for production. Also in the overall market the demand
for this dies is increasing more and more as pressures on cost increase.
Therefore it was necessary for EMO to carry out this application experiment
to fulfil the markets needs.
The design of the prototype took 5 months with an actual cost of 61,23k€.
Industrialisation and redesign costs (for CAN bus) are estimated at 58.3K€
The payback period on the FUSE investment of 56K€ is expected to be approximately
1,5 years with an ROI over the 10 year product lifetime estimated to be
The selling price of the new product is similar to the price of competitive
products but offers several technical advantages. These are mainly the
higher range of the possible thickness, shorter response time as well
as total thermal decoupling of the flat die and the expansion elements.
This AE is of interest for enterprises involved in the design of products
employing electronically controlled outlet regulation in the mm range
