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.
