Abstract
A method for manufacturing a high-strength steel wooden golf head solves the difficulty in reducing the thickness of the striking faceplate of a conventional wooden golf head. The method includes placing a shell mold having a crucible portion and a cavity portion in communication with the crucible portion on a rotary table, placing a metal ingot in the crucible portion, followed by melting the metal ingot into molten metal in a vacuum environment, rotating the rotary table to cause molten metal to flow into the cavity portion under a centrifugal force, gradually slowing down the rotary table after the molten metal cools and solidifies, destroying the shell mold to obtain a casting including a cast product portion, and separating the cast product portion from the casting to obtain a casting product of the wooden golf head having a tensile strength of 240-350 ksi and a minimum thickness of 1.4-1.8 mm not including a groove depth of the striking faceplate.
