Method of manufacturing a golf club head by plastic injection using inserts meltable core, and a golf club head manufactured by the method

A method of manufacturing a golf club head, said method comprising:

• affixing at least one insert and a meltable core together to form an insert/core assembly, with at least a portion of said insert projecting from said meltable core, said meltable core having a first melting point;
• immobilizing said insert/core assembly in a position in a mold to create a peripheral space between said insert/core assembly and interior walls of the mold;
• injecting plastic material into said peripheral space to coat said insert/core assembly, thereby coating the entirety of said projecting portion of said insert and forming a peripheral shell of the golf club head constituted by a plurality of walls, wherein said forming a peripheral shell of the golf club head comprises forming an exterior coating over said insert, coated by said injecting of plastic material, to encase said insert within said peripheral shell, said plastic material having a second melting point, said first melting point of said meltable core being lower than said second melting point of said plastic material;
• eliminating said meltable core to thereby create an inner cavity of said peripheral shell of the golf club head;
• and
• retaining said coated insert as a component of the golf club head manufactured by the method.
