Abstract
A method for manufacturing a golf club head having an embedded heterogeneous material includes preparing a shell mold having a cavity and a functional member embedded into the shell mold via an embedded portion, filling the cavity with a metal liquid to completely dip the non-embedded portion of the functional member in the metal liquid; breaking the shell mold to obtain a cast product, separating the golf club head cast member from the cast product to obtain a semi-finished golf club head having a casting material and a heterogeneous material, and pressing the casting material of the semi-finished golf club head to securely engage the casting material with the heterogeneous material. The functional member includes a non-embedded portion connected to the embedded portion and located in the cavity. The cast product includes a golf club head cast member.
