Abstract: The present invention provides a method of adjusting a coefficient of restitution (COR) of the face of a golf club head. A metallic assistant device is fixed on a center of a back of the face by friction welding or brazing. The metallic assistant may increases the central thickness of the face that may reduce the COR of the face.

Abstract: A method of manufacture a cup face with different thickness distribution is cutting a slice metal board with predestination shape from a metal board and stamping the slice metal board into an uneven metal board with predestination shape of rough and uneven on it then, milling one side of the uneven metal board to produce a board with different thickness. The final step is pressing the metal board with different thickness into a cup shape to form a cup face with different thickness distribution.

Abstract: A method of manufacturing a composite golf club head with a metal face includes the following steps. 1. Arrange two die and a mold plunger. 2. Combine the dies to form a mold cavity, which bottom is installed with a metal bottom board. 3. Put a bulk molding compound (B.M.C.) into the mold cavity. 4. Move the mold plunger into the mold cavity to compress the B.M.C. 5. Solidify the compressed bulk molding compound, and then separate the dies and the mold plunger to get a composite main body of the golf club head. The main body thus obtained has a main casing with a top opening. 6. Mount a composite top casing to the main casing to cover the top opening. Mount a metal front casing to a front side of the main casing to form the face.
