Plastic profile extrusion produces a part that has a continuous cross-section
such as a tube or channel. Using heat up to 600 degrees F and pressure the
profile is pulled at a specified line speed through a machined set of dies and
calibrators that match the part drawing.

The development process begins with a detailed
accurate part drawing defining all dimensions and
critical tolerances. Material selection is important
as different materials require different die design and
after-forming equipment. For instance, designing
dies for acrylic will not work for extruding polyethylene
and so on. Die design and manufacturing of dies
requires qualified and experienced toolmakers who
possess a comprehensive knowledge of various
plastic materials and their unique characteristics.
Now the extrusion process begins which entails setting extruder temperature
adjusting desirable line speeds and applying appropriate vacuum to sizing
calibrators. This stage can take several hours before an acceptable part is
achieved. In many cases the dies need to be adjusted and sometimes new
dies must be made,. If adjustments are necessary, the die testing procedure
has to be performed again.
When the profile meets the print requirements, the die testing phase is finished
and the part is submitted to the customer for approval. Now that we have the
data to extrude a part that meets the print, we can set up and run production
orders. Under normal conditions the development phase can take four weeks.
It is important that the customer leave ample time for development. Once the
part has been developed, production usually takes 2-3 weeks.
Once the dies have been completed it’s time to perform a die test. This involves
attaching the die plates to the extruder and setting up the downstream equipment.
Some materials require that the extrusion travel through chilled water, some
materials can be cooled with air alone and some require a combination of both.
In many cases the extrusion, once leaving the die, must then enter a vacuum
chamber or sizer, in order to maintain the intended shape. Now the plastic resin
must be loaded into the extruder and brought to a specific temperature before the
process begins. The set up procedure can take several hours.
