Manufacturing method of a top crown of a golf club head

Abstract

A manufacturing method of a top crown of a golf club head has steps of: providing a titanium alloy panel, providing a forging mold, and mounting the forging mold in a forging processing machine, heating the titanium alloy panel, driving the forging mold by the forging processing machine to hot forge the heated titanium alloy panel to form the top crown, and forming multiple reinforcing ribs on at least one of a bottom surface and a top surface of a crown body of the top crown. Thus, the top crown with different thickness due to concave and convex surfaces thereon can be formed directly. Shapes and sizes of the top crowns can be determined precisely, such that qualities of the top crown are stable. The method for manufacturing the top crown is pollution-free, can be operated easily, is environment friendly, and has high production efficiency.
