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.

plastic tolerances

plastic terms

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.


Understanding dimension tolerances see standard tolerance chart



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.
