Product Summary

The plastic extrusion screw is a screw used in Plastics extrusion which is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile. Such as pipe/tubing, weather stripping, fence, deck railing, window frames, adhesive tape and wire insulation are all the items of extrusion produces.

There are five possible zones in a thermoplastic screw. Since terminology is not standardized in the industry, different names may refer to these zones. Different types of polymer will have differing screw designs, some not incorporating all of the possible zones.

Most screws have these three zones: The feed zone (Also called solids conveying). This zone feeds the resin into the extruder, and the channel depth is usually the same throughout the zone; the Melting zone (Also called the transition or compression zone). Most of the resin is melted in this section, and the channel depth gets progressively smaller; Metering zone(Also called melt conveying). This zone, in which channel depth is again the same throughout the zone, melts the last particles and mixes to a uniform temperature and composition. Each zone is equipped with one or more thermocouples or RTDs in the barrel wall for temperature control.
