Abstract
A multiple metallic core assembly for use in production of a plastic injection-molded component is formed by injecting molten metal alloy into a core die at a fill stage of an indexing system, indexing the core die through a cooling stage to an unloading stage, and removing the core from the core die and inserting the core in one of a plurality of locations of the core assembly. Individual cores are continued to be formed as discussed above until all the locations of the core assembly are filled, and the core assembly is complete. Therefore, the core assembly is removed and transported to a plastic molding machine to produce the plastic component. Then, the core assembly is melted out from the plastic component in hot oil, and the molten metal alloy produced thereby is returned to a molten metal alloy tank.
