Abstract
One or more pre-molded resin inserts ( ) are placed in a metal mold and an outer molded resin body ( ) is formed about the insert. The cooling speed is increased by: forming the insert with projections ( ) to space a rear part of the insert from walls of the metal mold so that molten resin flows into position about the insert; forming convex parts ( ) on portions of the outer resin body adjacent the insert ( ); forming recesses ( ) in the molded outer housing, the recesses extending between the inserts and formed to receive fins of a front metal mold part; forming plural pin carrier inserts as one unit; or forming the inserts as layered bodies. This increases heat transfer from the outer body molten material to the cooler metal mold parts at regions adjacent to the pre-molded insert.
