ABSTRACT:
Molten metal is poured in an open top basin that communicates via a sprue with a cavity or expendable pattern in a mold to fill the cavity and partially fill the basin. After the casting metal has solidified through the gating that connects the sprue to the cavity, a tapered heat transfer member is introduced into the molten metal in the basin. A cooling medium is passed through the heat transfer member to extract heat from the metal in the basin and correspondingly cool the metal casting, thereby decreasing the cooling period prior to shakeout.
