ABSTRACT:
A method of manufacturing a golf club head that includes a peripheral shell constituted by an assembly of walls obtained by injecting a plastic material forming an inner cavity enclosing at least one inner insert kept immobilized by a partial plastic material coating of the shell. Prior to the injection step of the shell, an assembly is placed and immobilized in the mold which is comprised of a meltable core made of a second material having a melting point that is lower than the melting point of the plastic material in the space left free between the walls of the mold and the assembly, so as to coat the meltable core and all or a part of the free portion of the insert. Finally, all or a portion of the meltable core is eliminated to enable an inner volume to be freed so as to form the inner cavity.
