EXTRUSION DIE FOR BLOW MOULDING

摘要

A device for extruding and blow-molding thermoplastic tubular components with an extrusion head. The head has a central stem which is perforated in an axial direction. A distribution body lies radially around the stem so as to radially distribute the stream of thermoplastic material. An annular extrusion port is arranged downstream. The invention allows to avoid stagnations of material and to easily adapt the device to various types of thermoplastic material.
