Extrusion (Flow in Screw Extruders and Dies)

  • Chapter
Computational Analysis of Polymer Processing

Abstract

The extrusion process is one of shaping a molten polymeric material by forcing it through a die. By far the most common method of generating the required pressure, and usually of melting the material as well, is by means of one or more screws rotating inside a heated barrel. While the form of the die determines the initial shape of the extrudate, its dimensions may be further modified before final cooling and solidification takes place. Screw extrusion is the most important polymer process in that most thermoplastics and rubbers pass through an extruder at least once during their lives; if not during fabrication of the end product, then during the homogenisation stage. Also, in most modern injection-moulding machines, the preparation of melt for injection is carried out in what is essentially a screw extruder. Similarly, blow-moulding and calendering are often post-extrusion operations.
