Benefits of technology
The present invention provides a method for making a golf club head with a weight part that is integratedly connected to the club head. This is done by forging the club head and engaging the weight part into the club head. The method involves forming the club head, engaging the weight part into the club head, and then pressing the club head with the weight part to ensure a complete connection without any gaps. The technical effect of this invention is to create a stronger and more effective golf club head with improved weight distribution.
Problems solved by technology
However, the screw connection is not firm and the tungsten alloy screw may easily loosen or fall off, and causes a sound of vibration in striking.
However, since the materials of the weight part and the club head are different, the weight part easily splits or falls off from the club head in striking.
The weight part and the club head are not integrally connected to each other, such that the weight easily falls off or causes a sound of vibration in striking.

Embodiment Construction
[0022]With reference to FIG. 1, a manufacturing method of a weight parts integratedly connected with a forged golf club head in accordance with the present invention comprises the following steps: a club head forming step S1, at least one engaging recess forming step S2, at least one weight part engaging step S3, and a step of integratedly connecting the weight parts with the club head by forging S4.
[0023]With reference to FIGS. 1 and 2, in the step S1 of forming a club head by forging, a crude rod 10 is put in a raw forging die 20 and formed into a club head 30 by a forging process.
[0024]The crude rod 10 has a predetermined diameter and length based on the predetermined size of a golf club head. The crude rod 10 is made of metal such as carbon steel, stainless steel or the like. According to carbon content or the alloy elements of the material, the carbon steel for the crude rod 10 may be selected from 1020C,1025C,1035C,1045C,35CrMo,42CrMo etc; the stainless steel for the crude rod...

Abstract
A method of forming a weight part integratedly connected with a forged golf club head includes steps of a club head forming step, at least one engaging recess forming step, at least one weight part engaging step, and a step of integratedly connecting the at least one weight part with the club head by forging. A crude rod is provided into a raw forging die and formed to a club head by a forging process. At least one engaging recess is formed in a sole portion or a back portion of the club head by a machining method. At least one weight part is engaged into the at least one engaging recess of the club head. The club head with the at least one weight part is pressed by a forging process to make the material of the club head cover the at least one weight part completely without gaps.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a manufacturing method of a golf club head, especially to a manufacturing method of a weight parts integratedly connected with a forged golf club head.[0003]2. Description of Related Art[0004]A conventional iron golf club has a club head and a weight part mounted in the club head, mostly mounted in a sole portion or a back portion of the club head. The weight part usually has a higher specific gravity than the club head such that the iron golf club head has balanced weight distribution to improve striking performances or to increase the striking distance. Normally, material having a high specific gravity (10˜18 g / c.c) such as WC (Tungsten Alloy) is selected for the weight part.[0005]The conventional manners for connecting the weight part and the iron golf club are as follows:[0006]1. Screw connection:[0007]At least one tungsten alloy screw is screwed into a body of the iron golf club hea...
