Abstract

Thermoplastic sheets or tubes are passed through a press as they come hot from the extruder; the press turns them into components of uniform thickness. At the same time, holes may be stamped out, and hollows or grooves formed. The process may be made continuous, passing the freshly-extruded plastic between shaped rollers. The method is an economical alternative to injection moulding for small batches.
