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.

Golf club head manufacturing method

A manufacturing assembly and a method for locating a face insert in a golf club head during manufacture are disclosed herein. In particular, the manufacturing assembly comprises a face locating fixture sized to receive a golf club face insert and a pick fixture configured to removably attach to the face insert. The manufacturing assembly may further comprise a holding fixture sized to receive a golf club head and hold it in place while the face insert is aligned with the head during assembly.
