Abstract
A method includes placing a shell mold with a crucible portion and a casting portion in communication with the crucible portion on a rotary table, with the heterogeneous material including an embedded portion inlaying in the casting portion of the shell mold and a non-embedded portion locating in a cavity of the casting portion, placing a metal ingot into the crucible portion, followed by melting the metal ingot into molten metal in a vacuum environment, rotating the rotary table, causing the molten metal to flow into the cavity, destroying the shell mold after the molten metal solidifies to obtain a casting including a cast product portion separated from the casting to obtain a cast product of a golf club head, and removing the embedded portion of the heterogeneous material protruding from an outer periphery of the cast product of the golf club head.
