A first filler material is in the first recessed portion, and a second filler material is in the second recessed portion. The first filler material and at least a portion of the second filler material engage an inner surface of the back wall portion.

Abstract: Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head includes a body portion having an interior cavity, a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, and a top portion. The golf club head further includes a face insert portion coupled to an opening in the front portion to close the interior cavity at the front portion. The face insert portion includes a first portion located at a center portion of the face insert portion and having a first thickness, a second portion at least partially surrounding the first portion and having a second thickness, and a third portion at least partially surrounding the second portion and having a third thickness.

Abstract: 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 having a bottom portion, a toe portion, a heel portion, a front portion, a rear portion, an interior region, and a crown portion. The crown portion may have a first opening and a second opening. The crown portion may have a reinforcement portion extending between and separating the first opening and the second opening. The golf club head may include a cover portion attached to the crown portion. The cover portion may cover the first opening, the second opening, and the reinforcement portion. Other examples and embodiments may be described and claimed.

Abstract: 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.

Abstract: 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 body portion comprising a material having a first density and an interior cavity having a filler material therein comprising a material having a second density. The golf club head also includes a first mass portion coupled to the body portion and a second mass portion coupled to the hosel portion. The first mass portion and the second mass portion comprise a material having a third density. A port on the body portion is configured to receive the first mass portion. At least a portion of the first mass portion is below a horizontal midplane of the body portion. The first density is greater than the second density. The third density is greater than the first density.

Abstract: Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a method of manufacturing a golf club head may include forming a body portion having an interior cavity portion and a plurality of ports, forming a face portion, attaching the face portion to the body portion to close the interior cavity, injecting a polymer material into the interior cavity portion through a port in the body portion, and closing the ports with a plurality of mass portions. Other examples and embodiments may be described and claimed.

Abstract: 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 having a face portion with a face portion thickness extending between a front surface and a back surface.
