Patent ID: 8784715

Claim:
A production method of a composite molded part comprising: providing a pre-molded member consisting essentially of thermoplastic resin having crystallinity, subsequently forming at least one pre-molded part by pre-molding at least one insert member consisting essentially of metal, ceramic, resin, or a combination of those materials with the pre-molded member, applying heat treatment to a surrounding pre-molded member of said pre-molded part at a temperature of from 130° C. to 170° C. lower than a crystalline melting point of said pre-molded part of from 220° C. to 270° C. for about one hour, and then applying an insert molding process to an over-molding member to insert said pre-molded part, which has been cooled, solidified, and molded, into the over-molding member, and over-molding said at least one pre-molded part with an over-molded member consisting essentially of thermoplastic resin to form the composite molded part.
