A golf club head having a nonmetallic crown bonded to a frame in close proximity to the face.

A golf club head, preferably a putter head, comprising at least one structural support member is disclosed herein. The structural support member has a smooth, organic-looking aesthetic, with a continuously changing curvature along its spline and at least one surface, and preferably connects one portion of the golf club head to another portion. Where the support member connects to other portions of the golf club head, the surfaces of the member have a curvature that changes smoothly and continuously, lacking any sharp corners. The support member may be part of a lattice structure formed via binder jetting.

A hollow golf club head includes a metallic front body coupled with a composite rear body. The front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strikeface. The rear body includes a crown member coupled with a sole member. The sole member has a structural layer formed from a filled thermoplastic material, while the resilient layer is bonded to the external surface of the structural layer and is formed from a fiber-reinforced thermoplastic composite material. The resilient layer has an opening through which a metallic weight pad at least partially extends. The weight pad is bonded to the structural layer and includes an aperture for attaching a metallic weight. The golf club head can also have one or more structural members that are upright and connect the weight pad to the crown member.

A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end. Widths of each of the plurality of grooves vary in a direction extending between the heel end and the toe end.

Disclosed golf club heads include a body defining an interior cavity, a face, a sole, a crown, a skirt, and a hosel. Some embodiments include one or more of a split mass pad and/or one or more weight ports positioned in a sole portion of the body. Additionally or alternatively, one or more mass pads or weight ports may be positioned adjacent to the periphery of the sole portion. Some embodiments further include an adjustable head-shaft connection assembly configured to adjustably couple the hosel to a golf club shaft.

A golf club head includes a body having a face plate having a strike surface and an opposing interior surface, a rear end, and a sole connecting the faceplate with the rear end. The face plate, the rear end, and the sole partially define a cavity. An insert is positioned within the cavity, the insert presenting an insert surface facing the interior surface of the face plate and spaced therefrom.

A golf club head includes a golf club head body, a striking face, and an inner wall supporting the striking face. A ledge extends from a body into the interior of the golf club head body, and the inner wall is disposed within a gap between the striking face and the ledge. A rear surface of the inner wall is supported by a portion of the golf club head body, and a rear surface of the striking face is in contact with a portion of the inner wall. The inner wall may be inserted into the golf club head through an opening defined in the toe portion of the golf club head or the rear portion of the golf club head.

A golf club head with a sole having a low stiffness compliance zone, which allows the face to deflect downward upon impact with a golf ball, is disclosed herein. The compliance zone comprises a plurality of through openings that are filled with one or more filler pieces comprising a low modulus material, all of which are located within three inches of a face section measured along a front-to-back axis of the golf club head.

Methods of applying a polymeric coating to a rear face surface of golf club heads with variable face thickness are disclosed herein. The coating, which preferably comprises polyurea, improves the durability of the face and reduces the hits to failure ratio of the golf club head. The coating improves the performance of the golf club head because it allows for reduction in overall face thickness and easy post-process manipulation to allow for fine-tuning of mass properties after production. The reduction in thickness leads to overall weight reduction, because the polymer is roughly a quarter of the density of titanium or stainless steel, and also reinforces the face, thereby increasing the lifespan of the club.

In one embodiment the golf club head includes three main components, a frame component, a rear cap component, and a striking plate. In another embodiment the club head may also comprise a front component, which is manufactured as a single unitary piece, and a rear cap component. The front component may also be overmolded by a thermoplastic polymeric outer portion which may or may not cover the striking face and which provides additional reinforcement at the load bearing sections of the club head and allows a more facile connection to the rear cap component. In another embodiment, a club head having a main body, crown insert, sole insert and metal face plate frame is formed by forming the sole insert and crown insert from a polymeric material using a thermoforming or thermosetting process and then injection molding the main body over the sole insert, crown insert and metal face plate frame.
