A golf club head having elevated internal weighting that improves ball speed, reduces backspin, and increases launch angle is disclosed herein. In particular, the golf club head comprises a hollow body with a face, sole, and elevated weight bar, which is disposed inside the body and is fixed to heel and toe sides of the body, preferably with mechanical fasteners such as screws or bolts. The weight bar bridges a central portion of the sole, and a central section of the weight bar, which preferably comprises at least 50% of the overall mass of the weight bar, extends towards the face without actually making contact with the face. The sole also includes at least one slot extending perpendicular to the face and underneath the central section of the weight bar, the slot having a front-to-back length that is greater than a maximum front-to-back length of the weight bar.

A golf club head has a body defining a crown opening and a sole opening, a forward portion of the crown opening having a lip recessed below an outer surface of the crown and extending rearwardly. A composite crown insert is connected to the lip and covers the crown opening. A ratio of an outer surface area of the body and a combined outer surface area of the crown and sole inserts is less than 0.9. The club head has a crown height as measured relative to a ground plane at address, and there is a first crown height at a face-to-crown transition zone, a second crown height at a crown-to-skirt transition zone, and a maximum crown height that is greater than the first and second crown heights, the maximum crown height being located on the crown insert at or rearward of the lip.

Disclosed herein is a casting cluster for casting a body of a golf club head made of titanium or a titanium alloy. The casting cluster comprises a receptor and a plurality of runners coupled to the receptor and configured to receive molten metal from the receptor. The casting cluster also includes at least forty main gates. At least two of the main gates are coupled to each of the runners and each main gate is configured to receive molten metal from a corresponding one of the plurality of runners. The casting cluster further comprises at least forty molds. Each mold of the at least forty molds is configured to receive molten metal from a corresponding one of the main gates and to cast a body of an iron-type golf club head.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion with a toe portion, a heel portion, a top portion, a sole portion, a back portion, and a front portion. The golf club head may include an interior cavity. Other examples and embodiments may be described and claimed.

A resilient face insert for a golf club head, preferably a putter head, is disclosed herein. In particular, the face insert comprises a plurality of hinge features spaced from a striking surface to ensure consistent ball speed across the striking surface. At least a portion of each hinge feature extends parallel to the striking surface without making contact with the striking surface. In the preferred embodiment, each hinge feature comprises a tab portion that is spaced from the striking surface by a stem portion and that extends parallel to the striking surface. The hinge features may be co-molded with a polymeric backing material in order to further improve performance of the face insert.

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.

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 may include a body portion having a front portion, a first interior cavity in the body portion having a first opening in the front portion, a second interior cavity at least partially surrounded by the first interior cavity and having a second opening in the front 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 face portion is attached to the front portion to close the first opening. The second face portion is attached to the front portion to close the second opening. 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.

An iron-type golf club head comprising a topline, a sole in opposed relation to the topline, and a front portion extending from the topline toward the sole. The front portion includes a leading edge, a substantially planar hitting region including a face center, and a peripheral region. The peripheral region at least partially surrounds the hitting region such that the hitting region and the peripheral region define therebetween a visually-recognizable hitting region boundary line including a sole-proximate boundary line segment such that when the club head is oriented in a reference position relative to a virtual ground plane, and in a virtual vertical plane perpendicular to the hitting region and passing through the face center, the sole-proximate boundary line segment is vertically spaced above the leading edge by a distance D1 that is no less than 2.5 mm.

A golf club head including a body having a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion. The body further includes a cavity in the front portion. The cavity having a protrusion and a step configured to receive a strikeplate, such that a gap exists between the strikeplate and the inner surface of the cavity.

A golf club head is provided with a body that has an address position with a zero degree bounce portion on the sole and a center sole position with a multi-relief surface of the sole having a negative bounce portion. The negative bounce portion may comprise a negative 0.5 to a negative 4.0 degree surface. In one embodiment, the multi-relief surface may comprise the negative bounce portion and a cutaway portion extending to the back of the sole, which may have a depth of about 0.05 to 0.5 inch from a regular sole surface. In another embodiment, the golf club head includes a weight system to adjust the center of gravity. In one embodiment, the weight system is a tube having a weight at one end that may be inserted into the golf club head to move the center of gravity at least forward and backward within 6 mm and up and down within 6 mm. Preferably, the tube is angled downward toward the face by at least 3 degrees.
