A core ring assembly for use in production of a plastic injection-molded component is formed by injecting molten metal alloy into core dies to produce two intricately shaped ring type elements - one male, one female. Removing the male and female ring elements from the core dies and combining the two elements in an assembly machine to form a uniform, geometrically symmetrical, integral core ring assembly. The core ring assembly is transported to a plastic molding machine for overmolding the core ring assembly with either thermosetting or thermoplastic material. Then, the core assembly is melted out from the plastic component in a hot oil bath or induction melt-out, and the molten alloy recovered thereby is returned to a molten metal alloy tank for reuse.
