Method for Manufacturing a High-Strength Steel Wooden Golf Head

摘要

A method for manufacturing a high-strength steel wooden golf head is provided to solve 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 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.

1. A method for manufacturing a high-strength steel wooden golf head, comprising:
placing a shell mold on a rotary table, with the shell mold comprising a crucible portion and a cavity portion in communication with the crucible portion via a coupling portion, with the cavity portion comprising a hosel-shaping region, a face-shaping region, a heel-shaping region, a sole-shaping region and a toe-shaping region, with the hosel-shaping region, the face-shaping region, the heel-shaping region, the sole-shaping region and the toe-shaping region interconnecting with each other; placing at least one metal ingot in the crucible portion of the shell mold; melting the at least one metal ingot into molten metal in a vacuum environment; driving the rotating shaft to rotate the rotary table, causing the molten metal to flow into the cavity portion of the shell mold under a centrifugal force generated by the rotation; gradually slowing down the rotating shaft after the molten metal cools and solidifies; destroying the shell mold after the molten metal completely solidifies, obtaining a casting comprising a cast product portion; and separating the cast product portion from the casting to obtain at least one casting product of wooden golf head having a hosel, a face, a heel, a sole and a toe corresponding to the hosel-shaping region, the face-shaping region, the heel-shaping region, the sole-shaping region and the toe-shaping region, respectively; wherein the at least one casting product of wooden golf head has 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.
