PVC compound for Rigid Extrusion

The Rigid Plastic profiles that we extrude are specific to our customer’s requirements. Rigid plastic extrusions are more commonly being used as a replacement for metal in automotive and construction applications. In addition rigid profiles are suitable for visible applications as they take embossing and textures very well.

Plastic granules are fed into the hopper of the extruder and are drawn down into the screw. The barrel and screw are heated by external heating elements. As the plastic granules move along the screw they melt and are forced through a die which is located at the end of the barrel. The die contains the cross section of the profile of the extrusion required. The profile is then water cooled through water baths before being cut to length and packaged. To enhance the profile post extrusion techniques can be carried out such as printing, embossing and adhesion application.
