ABSTRACT:
A manufacturing process of a golf club head for tightly and firmly affixing a striking plate, which is preferably made of titanium or titanium alloy, on a head body made of other metal material includes the following steps of (1) forming a receiving groove on a head body of a golf club which has a predetermined original size and shape; (2) heating the head body until the head body expands to slightly enlarge the size of the receiving groove; (3) planting a striking plate, which is made of titanium or titanium alloy and has a size and shape slightly larger than the original size and shape of the receiving groove of the head body before heating, into the heated receiving groove of the head body; and (4) moving the head body with the striking plate to room temperature until the receiving groove will shrink back to the original size. Therefore, the striking plate is tightly and firmly engaged within the receiving groove so as to integrally attach with the head body to form the one body golf club head, so that the chance of the looseness of the striking plate from the head body would be eliminated.
