  • INVESTMENT CASTING WITH EXOTHERMIC MATERIAL
    Publication number: 20020124984
    Abstract: Method and investment shell mold for casting comprising introducing molten metallic material into an investment shell mold to fill a mold cavity and provide an upper surface of the molten metallic material above the mold cavity. An initially closed, destructible region of the mold then is broken to provide an entry opening through which exothermic material is placed on the upper surface of the molten metallic material to provide a source of molten metallic material to accommodate shrinkage of a casting as it solidifies in the mold cavity.
