Abstract
A method of producing a molded article includes the steps of positioning an insert within a first mold, and filling the first mold with a low melt allow to form a lost core assembly. The lost core assembly includes an external shape corresponding to the desired cavity formed within the molded article. The inserts are supported within the lost core and form a part of the surface of the cavity of the completed molded article. The lost core assembly is over-molded with a thermoplastic or thermoset material. The alloy material is removed leaving the inserts within the molded article to form specific portions of the cavity.
