Golf ball head capable of reducing upper cover thickness and its preparing method

Abstract

This invention relates to a golf ball head that its top cover thickness can be reduced and its producing method. It is one piece formed ball head with top cover, glue mouth and annular passage are set cervical part side of the head, the top cover forms a manufacturing district, thin top end face and thick banquette is formed on the district, inner fovea area and impact bounce area are formed at back part. Central thick and two ends thin state is formed near the side of the ball kick panel. Perimeter thickness of head out of the area is original thickness, weight after abrasion is moved to underside and backside of the head to make the head reach low gravity center as increased weight, and absorbing shaken is increased, and ball sweet area is enlarged.

Description

technical field [0001] The present invention relates to a golf head capable of reducing the thickness of the upper cover and its manufacturing method. In the case of increasing the weight, it can achieve the effect of low center of gravity, deep center of gravity, increase shock absorption and expand the sweet spot of hitting the ball. Background technique [0002] Golf has been a popular leisure sport at present, and along with the popularization of golf, golf utensils are also gradually paid attention to. Among golf equipment, the most important thing is to push the club. The quality of the club will affect the stability of the ball when hitting the ball and the flight condition of the ball after hitting the ball. Among the clubs, the most important thing related to the result of the ball is the First push the ball head.

Problems solved by technology

[0003] The traditional one-piece golf head, whether it is made of stainless steel metal or titanium alloy metal that most golfers like, so far, all major manufacturers are working hard to develop how to improve the center of gravity of the golf head and expand the hitting range. For the required effects such as the sweet spot of the ball, as far as the titanium alloy ball head manufactured in the industry is concerned, when the ball head is precision casted, the thinnest wall thickness that can be cast due to the best flow coefficient of the material is about 0.9mm. If the thickness is less than the aforementioned thickness, the ball head will be more difficult to cast and form. The rate of bad molding of the ball head will be higher. Therefore, if it is necessary to add weight to the lower and rear sides of the ball head to achieve a low center of gravity, a deep center of gravity, and even install shock-absorbing materials to increase the shock-absorbing effect, Both will increase the weight of the ball head. Therefore, in order to achieve the principle of maintaining the same size of the ball head, the industry has made many improvements to reduce the weight of the ball head cover itself, such as: laser welding or explosive welding The thin plate is placed on the upper cover, or the upper cover is corroded with strong acid to make the upper cover thinner; The weld bead also affects the sound when hitting the ball, making it impossible to supply the market at a fair price
