Structure of parts made from plural composite pieces and method of building those parts

A pre-mold part is formed by pre-molding the insert part composed of composite materials composed of metal, ceramic, resin or any combination of those materials with the pre-mold part composed of thermo plastic resin having crystallinity, and then, the pre-mold part is inserted into the over-mold pa...

Beschreibung
Zusammenfassung:	A pre-mold part is formed by pre-molding the insert part composed of composite materials composed of metal, ceramic, resin or any combination of those materials with the pre-mold part composed of thermo plastic resin having crystallinity, and then, the pre-mold part is inserted into the over-mold part composed of thermo plastic resin. After applying the heat treatment with the temperature lower than the crystalline melting point of the pre-mold part to the pre-mold part surrounding the insert part formed as the composite mold part surrounding the pre-mold part, the insert molding is completedfinally. Mold parts having high-reliable insert parts enable to establish firm contact between the insert part and the resin surrounding the insert part without no gap at the interface between those parts can be obtained by a low-cost production method.
