Abstract

A manufacturing method of an integrally forged golf club head has acts of: forging a crude rod to form a blank of a main body of a golf club head, mounting a weight in a mounting recess of the blank of the main body of the golf club head, covering the mounting recess with an outer cover, and then welding and forging the blank of the main body of the golf club head and the outer cover to form a golf club head. Thus, the at least one weight is securely held in the golf club head and does not come off the golf club head, and also no noise occurs when the golf club head strikes a golf ball. Furthermore, the at least one weight is not exposed so that the golf club head has a good appearance and improved quality.

Claims

1. A manufacturing method of an integrally forged golf club head comprising acts of:

providing a crude rod;

forging the crude rod to form a blank of a main body of a golf club head, wherein

the crude rod is pressed with molds to form the blank of the main body of the golf club head; and

the blank of the main body of the golf club head has at least one mounting recess formed on a back of the blank of the main body of the golf club head;

mounting at least one weight in the at least one mounting recess of the blank of the main body of the golf club head;

mounting at least one outer cover on the back of the blank of the main body of the golf club head and each one of the at least one outer cover covering a corresponding mounting recess where a corresponding weight is mounted, wherein the at least one outer cover and the blank of the main body of the golf club head are made of the same material;

welding the at least one outer cover to the blank of the main body of the golf club head to form a blank of a golf club head; and

forging the blank of the golf club head to form a golf club head, wherein

the blank of the golf club head is pressed with molds to form the golf club head;

the at least one outer cover and the blank of the main body of the golf club head that are made of the same material are press-forged to one piece; and

the at least one weight is securely held in the golf club head.

2. The manufacturing method as claimed in claim 1, wherein the crude rod is bent by a bending machine in advance before forging to form the blank of the main body of the golf club head.

3. The manufacturing method as claimed in claim 2, wherein in the step of forging the crude rod, the crude rod is forged through a single forging process to form the blank of the main body of the golf club head.

4. The manufacturing method as claimed in claim 2, wherein in the step of forging the crude rod to form the blank of the main body of the golf club head, the crude rod is forged through multiple forging processes to press the crude rod to the blank of the main body of the golf club head.

5. The manufacturing method as claimed in claim 4, wherein the forging processes comprise a rough forging process and a fine forging process to forge the blank of the main body of the golf club head in sequence.
