Abstract: Top and bottom ferrous carrier plates have a plurality of pairs of mating insert receptacles in full carrier plates and interlocked partial carrier plates. Pairs of mating nonferrous pre-molded inserts with mating mold cavities insert with a three axis floating fit into mating insert receptacles. Insert contact faces each comprising a flat surface portion having a plurality of mating alignment elements adapted for automatic precision alignment of the mating pair of pre-molded inserts. An injector structure comprising a plunger and pot bushing structure communicates with a pot on each top pre-molded insert. The bushing structure has a solidifying cavity and stripping structure so that retraction of the plunger separates the solidified material from the plunger face for automatic removal of surplus injected material after each molding cycle.

Abstract: Top and bottom ferrous carrier plates have a plurality of pairs of mating window cavities. Pairs of mating nonferrous pre-molded inserts with mating mold cavities snap into mating window cavities with a rubberized retainer ring therebetween to create floating mating pre-molded insert molds in multiple material carrier plate assemblies. Liquefied material is dispensed through pot bushings and plungers in each top pre-molded insert. The liquefied material flows though gate openings located in each insert top surface filling the mold cavities. The liquefied material then solidifies to its permanent shape in the mold cavities.
