Beschreibung
Zusammenfassung:	The invention relates to a process for injection moulding plastic parts with hollow shapes or curved shapes tapered towards one another and the core used for carrying out the process. The invention consists in bringing the core before carrying out the injection moulding process with plastic to a low temperature. A core used for carrying out the process according to the invention is characterised in that it comprises a metal part of low thickness, corresponding to the countersleeve (draught) of the parts to be moulded in moulds, and a low-melting alloy and is arranged around a solid spindle (pin, peg) which is of large dimensions and made of a readily heat-conducting metal with a relatively high melting point.
