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.

A golf club head with a crown comprising an inner crown portion and an outer crown portion. The inner crown portion may be made of a low density or low elastic modulus material. The outer portion of the crown defines an opening to the cavity. The inner portion of the crown is attached to the outer portion of the crown such that the opening is covered by the inner portion of the crown.

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 golf club head in accordance with the present invention 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), all combined with a high MOI about the X and Y-axis (MOI-X and MOI-Y) and maintaining a consistently and relatively low CG location measured along a direction tangent to the hosel axis along the X-Y plane (CG-B).

Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a body portion of a golf club head includes a front portion. A face portion is coupled to the front portion. The face portion includes a central strike portion and a perimeter. A plurality of projections extend from the face portion to provide a ball striking surface for impacting a golf ball. Each projection is defined by a plurality of grooves intersecting one another within the face portion. The plurality of projections are each defined by an area ratio between a base portion area and a peak portion area. The area ratios of the plurality of projections decrease from the central strike portion to the perimeter of the face portion. Other examples may be described and claimed.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head includes a recessed opening between a front opening and a back wall portion, a front plate portion coupled to the recessed opening to enclose a first interior cavity in the golf club head between the front plate portion and the back wall portion, a face portion coupled to a front portion to enclose a second interior cavity between the face portion and the front plate portion, a first filler material at least partially filling the first interior cavity, and a second filler material at least partially filling the second interior cavity. The first filler material and the second filler material have at least one different physical property. Other examples and embodiments may be described and claimed.

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 an outer surface; a recessed channel formed in the outer surface; and a weight assembly including: a weight at least partially disposed within the recessed channel and configured to move therein, the weight including a main body and a protruding tongue, the protruding tongue including a distal tongue portion and a proximal tongue portion, a cover extending at least partially over the recessed channel, having a window cutout shaped and sized to block at least part of the distal tongue portion from moving through the window cutout, and having a slot cutout forming, together with a portion of the window cutout, an opening in the cover that is shaped and sized to allow movement of the distal tongue portion through the opening, and a slot wedge at least partially filling the slot cutout and forming a portion of the window cutout.

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 lightweight aft portion could be formed of a multi-layered sandwich material with at least one layer having low damping properties. The lightweight aft portion may be formed out of a lightweight crown sub-shell and a lightweight sole sub-shell, both of which combine to receive a weighting system.
