Abstract
A process for manufacturing a golf-club head is disclosed comprising; shaping a fluid-removable core in the general form of the club head, placing a flexible inflatable bladder around the core, wrapping over the assembly of core and bladder at least one ply of fiber impregnated with a curable resin, placing the assembly of core, bladder, and impregnated fiber into a female mold, forming a cured part in the form of a golf-club head by inflating the bladder to force the plies against the inner surfaces of the mold and heating the mold to cure the resin, removing the cured part from the mold, disintegrating the fluid-removable core with a fluid sufficient to allow removal of the bladder from the interior of the cured part through a hole in the cured part, removing the bladder through the hole with any residues of the core within the bladder to form a hollow molded club head with a hollow interior essentially free from non-functional materials.
