Process for extrusion moulding of hollow bodies of thermoplastic and / device, extrusion molding the hollow body /

摘要

Process for the extrusion of hollow thermoplastic bodies / molding, and extrusion molding device / body is hollow.Process and device for extrusion moulding of hollow bodies of thermoplastic / using at least an extruder (1) and at least two molds (4, 5) and comprising the extrusion of a material flow, its cut in parisons to produce the hollow body, alternately in the first (4) and then n The second mold (5). The process may work in parallel for certain of its stages.This process and its device is very suitable for the production of hollow bodies of complex three-dimensional geometry with a high productivity.
