Producing method for cylindrical shaped molded padding made from plastic, particularly possessing pin of hollow space, involves placing melt plastic corresponding to volume of bolt over nozzle in hollow space

摘要

The method involves placing a melt plastic corresponding to the volume of the bolt (3) over a nozzle in a cavity (4) of a tool (1) determining the form of the bolt by injection molding. A displacement of the melt plastic is produced by the injection of the fluid in such a manner that the cavity of the tool is completely fills. A hollow space (2) of the bolt is produced by the injection of the fluid into another melting liquid soul of the melt plastic. An extraction of the cylindrical shaped molded padding is take place from the tool after partial hardening of the melt plastic.
