  • Patent number: 11135648
    Abstract: A method of manufacturing golf club heads, and particularly putter heads, using metal injection molding and plasma polishing is disclosed herein. The metal injection molding process is facilitated with a base tool having a golf club head shaped cavity and interchangeable hosel core tools. The use of interchangeable hosel core tools allows a manufacturer to quickly and easily alter the overall shape of the putter head, and greatly reduces the number of base tools needed to create an entire line of putter heads with different hosel designs. This plasma polishing process yields a glossy cosmetic shine appearance, increases corrosion and rust resistance, and provides a smoother surface to which post process operations can adhere.
