The process of extrusion involves the shaping of a pre-heated polymeric material. The heated material is forced through a die plate to form the desired shape. Typically, extruders are of the screw type where the screw continuously forces the feed, inducing further frictional heating of the extrudate and ensuring consistent flow properties.

The profile of the die plate must be approximate to the final section shape. Softer polymers require considerable distortion allowances as die swell will likely occur immediately after the extrudate emerges from the die orifice. Post-extrusion curing equipment is employed at a later stage to cure the extruded material.

The continuous extrusion process can be used to manufacture dense and sponge materials alike. In addition, the process is suitable as an interim step in the overall production process. This makes the continuous cure extrusion process ideal for the manufacture of tubing or profiles that can be further processed by cutting, joining, splicing, or adding adhesive (PSA) to the extrudate,  just to name a few.

 

Archer employs several different types of extruders and continuous cure operations:

  • HAV
  • Infra-red
  • Molten salt

These curing methods allow for tailoring of product specific processes.
