A method of manufacturing a golf club head including a plurality of structural connectors, and particularly solid rods proximate the face, is disclosed herein. The method includes the steps of preparing a wax of a golf club head body, the body including first and second through-holes, a hollow interior, and first and second receiving pockets, preparing waxes of first and second solid rods, inserting the first solid rod wax into the first through-hole and seating its lower end in the first receiving pocket, inserting the second solid rod wax into the second through-hole and seating its lower end in the second receiving pocket, bonding each of the first and second solid rods to the body with an adhesive material to form a combined wax mold, and casting a golf club head from the combined wax mold.

A manufacturing method of a golf iron head by combining different metal materials includes a pre-forming step, an engaging step, a pre-heating step and a forming step. A head body and a strike plate are provided in the pre-forming step to combine with each other. The strike plate is engaged with the head body in the engaging step, and the strike plate and the head body are pre-heated together. The forming step combines the head body and the strike plate as a one-piece iron head without clearances. Because the materials of the head body and strike plate are different and the connection force between the head body and the strike plate is increased, the mechanical properties and striking performance are improved and noises upon striking are eliminated.

A co-forged iron type golf club is disclosed. More specifically, the present invention discloses an iron type golf club head from a pre-form billet that already contains two or more materials before the actual forging process resulting in a multi-material golf club head that doesn't require any post manufacturing operations such as machining, welding, swaging, gluing, and the like. The resultant golf club head may be capable of achieving center of gravity locations previously unachievable without utilizing this co-forging technique. The resultant golf club head may be used to create a set of golf club heads with center of gravity locations that are more advantageous throughout a set of golf clubs.

A method of manufacturing a forged iron type golf club head with a cavity. The method of manufacturing comprises forming a billet into an intermediate club head body with a strike face comprising an upper region and a lower region; hot pressing a cavity into the rear portion of the intermediate body; and bending the strike face of the intermediate club head body to form a golf club head with a cavity and a planar strike face. Other embodiments are disclosed.

An iron-type golf club head with a cavity formed via a multi-stage forging process. The forged iron-type golf club head is formed from a single billet of material. An intermediate step of the multi-stage forging process creates a cavity in the iron-type golf club head which can receive an insert. The resultant iron-type golf club head has a substantially lower center of gravity and higher moment of inertia when compared to a traditionally forged iron-type golf club head lacking a cavity. Additionally, the resultant iron-type golf club head has a more solid feel than a traditionally cast iron-type golf club head as a result of the tighter grain structure the forging process yields.
