Abstract

The invention discloses a manufacturing process of a golf club head. The manufacturing process of the golf club head includes the following steps of material preparation, specifically, stainless steelpowder with the grain size D90 smaller than or equal to 22 micrometers is adopted, and adhesives are prepared; mixing, specifically, the stainless steel powder is preheated, then the adhesives are added, and banburying is conducted after the adhesives begin to melt; injection molding, specifically, the mixed materials are extruded from a mold cavity to be formed; degreasing, specifically, degreasing is catalyzed through nitric acid, so that the adhesives in a formed product are removed; and sintering, specifically, the degreased product is subjected to high-temperature sintering. According tothe manufacturing process of the golf club head, the final product is obtained through injection molding of the metal powder, degreasing and sintering, and the manufactured product is high in accuracy, small in weight tolerance, good in consistency and higher in post-machining efficiency with only a little post-machining; the product is good in consistency, and the playing experience of golf players is better; and equipment investment involved in the manufacturing process is low, and good economical benefits are achieved.

Description

technical field [0001] The invention relates to a golf head manufacturing process. Background technique [0002] At present, golf ball equipment manufacturers mainly use casting or forging to make golf ball heads. The ball head is made by casting and then dewaxed many times. The process is long, the product size accuracy is low, the consistency is poor, and the weight tolerance is large; the forged ball head is formed by machine forging and has high requirements for materials. , the production cycle is longer and the cost is higher, and it is mainly suitable for the manufacture of high-end ball equipment. After casting or forging, post-processing costs are high, and the product consistency after processing is still poor; therefore, the invention provides a high-efficiency, low-cost, and high-precision golf head manufacturing process to solve the above problems. Contents of the invention [0003] In order to solve the above problems, the present invention provides a golf ...
