A method of forming a golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the method forms a golf club head that achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA).

Method of forming a golf club head with improved inertia performance

Golf club head

A golf club head that is capable of preserving the metallic acoustic signature of an entirely metallic golf club head all while utilizing a lightweight composite material is disclosed herein. More specifically, the golf club head in accordance with the present invention creates a frontal acoustic chamber in conjunction with a rear weight saving chamber via a panel member barrier is disclosed. The panel member may even be combined with an optimized thickness relationship at the transition region between the striking face portion and the panel member to further optimize the performance of the golf club head.

Multi-material golf club head

A multi-material golf club head having an improved performance is disclosed. More specifically, the present invention relates to a multi-material golf club head having a metallic frontal portion and a lightweight aft portion with an addition of an internal ribbon support member. The present invention may also further be comprised of a weighting mechanism that is accessible via an opening in the lightweight after portion but connects directly to the metallic frontal portion to mitigate any of the structural integrity issues associated with installing weights in a lightweight portion of a golf club head.

A golf club head including a crown, a sole, a hosel, a face, a weight port, an internal cavity, and a stiffening member. The weight port is affixed to the sole. The stiffening member is located in the interior cavity and permanently affixed to the hosel. The stiffening member is also permanently affixed to the sole and the weight port.

Golf club head with stiffening member

A golf club head having an exterior surface opposite the hollow golf club interior, the body having a center of gravity, wherein the body comprises an elongate weight receptacle, a weight retainer located in the weight receptacle, wherein the weight receptacle comprises a plurality of weight mounts, wherein the weight retainer is configured to slide along the weight receptacle between each of the plurality of weight mounts when the weight retainer is unlocked, and wherein the weight retainer is configured to reside in any of the plurality of weight mounts when the weight retainer is locked, and wherein the weight receptacle comprises a weight receptacle installation feature configured to receive the weight retainer, wherein the weight receptacle installation feature is located between two of the plurality of weight mounts, wherein the two of the plurality of weight mounts are located adjacent one another.

Golf club with movable weight

A golf club head including a crown, a sole, a hosel, a face and a flexure. The flexure provides compliance during an impact between the golf club head and a golf ball, and is tuned to vibrate, immediately after impact, at a predetermined frequency. A slot is included in a portion of the golf club head and works with the flexure to further tune performance.

Golf club head with flexure

A golf club head made out of multi-material is disclosed herein. More specifically, the golf club head in accordance with the present invention has at least a portion of the body of the golf club head that is further comprised out of a base layer and a lightweight cover layer. The base layer may have a plurality of cutouts to help reduce unnecessary mass and the lightweight cover layer may be made out of an ultra-lightweight material to further reduce the unnecessary mass. The resulting golf club head may generally have a deep CG wherein the CG-B location is about 37 mm, and a CG-C location is greater than about 30 mm.
