Abstract

Method and apparatus for casting a metallic material involves the steps of disposing an investment mold in a container, holding the container with the mold therein relative to a platen of a casting machine such that one or more mold cavities communicate to a shot sleeve to receive molten metallic material therefrom, introducing the molten metallic material in the shot sleeve under hydraulic pressure into the one or more mold cavities of the mold while the container is held adjacent the platen, and at least partially solidifying the metallic material in the one or more mold cavities.
