Then, the metal cement injecting step 22 is performed. In this step, metal clay of a mixed metal powder and a polymer binder is injected into the first and second molds 31 and 32 from the injection hole 331 at a high pressure. The blast groove 33 causes the metal cement injected into the blast groove 33 to form a shape corresponding to the primordial embryo 4 of the blast groove 33 due to the high pressure.

The formed embryo 4 includes a primordial body 41, an primordial hub 42, an primordial anchor 43, an primordial bulge 44, and an injection-molded rim 45, the primordial The body 41 has a primordial appearance surface 411 which is continuously smooth and undulating and an initial embryo inner surface 412 spaced apart from the primordial design surface 411. The primordial pivot socket 42 extends integrally from the primordial body 41. The embryo joint 43 has an ejector weld 431 extending from the priming inner surface 412 away from the priming surface 411, and the primordial convex line 44 is correspondingly formed in the primordial a surface 412 corresponding to the initial inner surface 412 and located at the primordial weld 431. Further, the priming body 41 further has a connection between the primordial surface 411 and the blast The top side 413 of the same side of the surface 412 has a primordial joint side 421 extending integrally from the top side 413. The top side 413 and the primordial joint side 421 are also smoothly continuous. The curved surface, so that the overall head of the old head 4 presents a continuous smooth and undulating metal texture without a sharp edge appearance.
