A manufacturing process of a golf club head includes the following steps: (a) Construct a hollow golf club head frame which at least two opposite supporting pins protruding outwardly from an outer perimeter thereof. (b) Position the hollow golf club head frame within a precision mold which has an internal molding cavity, wherein the internal molding cavity of the mold has at least two opposite pin slots to fittingly receive the two respective supporting pins of the hollow golf club head frame for defining an uniform intermediate gap between the outer perimeter of the hollow golf club head frame and an inner wall of the mold. (c) Fill out the intermediate gap between the mold and the hollow golf club head frame with a melted metal or alloy in order to form a rigid outer shell to uniformly conceal the hollow golf club head frame. (d) Remove the mold after the outer shell and the hollow golf club head frame becomes an integral unit of golf club head, wherein each supporting pin has a residual tail protruded from the outer shell. (e) Grind the two residual tails of the supporting pins to achieve a smooth outermost surface for the golf club head. The golf club head manufactured by the above manufacturing process can provide a lighter body weight, high impact vibration resistant and durable single unit.
