Method for manufacturing hollow cylindrical clutch hub made of thermoplastic synthetic material, involves injecting synthetic material with multiple injecting casting nozzles corresponding to multiple synchronization clutches

摘要

The method involves injecting a synthetic material with multiple injecting casting nozzles corresponding to multiple synchronization clutches and these are rotating symmetrically to each other like the synchronization clutches. The casting nozzles are arranged equally in a plane running parallel to the front surface. An independent claim is also included for a hollow cylindrical clutch hub made of thermoplastic synthetic material.
