Abstract: A golf club head includes a club head main body, a club head complementary component, and a protection component. The club head main body defines an opening which includes an inner opening section and an outer opening section spatially connected to and located outside the inner opening section. The club head complementary component is disposed in the inner opening section and connected to the club head main body. The protection component is disposed in the outer opening section and connected to the club head complementary component to cover the club head complementary component. The protection component is made of a carbon fiber impregnated with thermoplastic polyurethane, and has a Shore D hardness ranging from 40 to 70.

Abstract: A golf club head includes a main body and a plate member disposed on the main body. The plate member includes a plurality of carbon fiber layers which are stacked on each other and are impregnated with a thermoset carbon fiber resin containing carbon nanotubes. The carbon nanotubes are present in an amount ranging from 0.01 wt% to 5 wt%, based on the total weight of the thermoset carbon fiber resin.

Abstract: A golf club head includes a club head main body and a crown. The club head main body includes a main portion, and a receiving portion connected to the main portion. The main portion has an outer shell surface, and an upright side wall surface interconnecting the outer shell surface and the receiving portion. The crown includes a covering portion, and a protrusion protruding upwardly from an outer periphery of the covering portion, adjoining the side wall surface, and having a to-be-ground surface flushing with the outer shell surface. A height difference between the protrusion and the covering portion prevents the covering portion from being ground.

Abstract: A method for manufacturing a golf club head having a weight member includes: providing a weight block made of a metal material; disposing an isolation layer on the weight block to form the weight member; delivering a wax material to form a wax pattern covering a portion of the weight member; coating the weight member and the wax pattern with a shell mold plaster to form a shell mold covering the same; performing a de-waxing process which leaves a mold cavity in the shell mold; and casting a molten metal material in the mold cavity to form a club head main body, and removing the shell mold to form the golf club head having the weight member embedded in the club head main body. A golf club head manufactured by the method is also disclosed.

Abstract: A golf club head and a method for manufacturing the same are provided. The golf club head includes a club head body and a striking face unit. The club head body includes a main body and a coupling portion extending from the main body, defining an opening, and having an end that is concaved toward the main body to form an engaging recess. The striking face unit has a connecting portion and covers the opening. The connecting portion is inserted into the engaging recess of the coupling portion and is connected to the club head body. The club head body is made of a first metal material and the connecting portion is made of a second metal material having a melting point higher than that of the first metal material.

Abstract: A golf club head includes a striking plate, a base block, a connecting unit and a bottom plate. The striking plate includes a bottom end and a top end. The base block is disposed separately from and extending away from the bottom end of the striking plate. The connecting unit is connected to the striking plate and the base block. The bottom plate is formed as a separate piece from the striking plate and the base block, and is connected to the bottom end of the striking plate and the base block. The base block and the bottom plate cooperatively form a sole portion of the golf club head and define a recess therebetween.

Abstract: A golf club head and a striking plate for connecting a shell of a golf club head are provided. The striking plate includes a plate body and at least one rib member. The plate body has a crown-connecting side, a sole-connecting side, a toe-connecting side, a heel-connecting side respectively connecting to a crown, a sole, a toe and a heel, a central portion surrounded by the crown-connecting side, the sole-connecting side, the toe-connecting side and the heel-connecting side, a front striking face, and a rear face. The at least one rib member includes two opposite end portions projecting rearwardly from the rear face, and a bridge portion connected between the two opposite end portions and spaced apart from the rear face.
