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 and a face portion attached to the body portion that comprises a center portion having a first thickness, a perimeter portion having a second thickness greater than the first thickness, spoke portions extending radially from the center portion to the perimeter portion, and recessed portions. Each recessed portion is located between two spoke portions, and each recessed portion extends from the center portion to the perimeter portion. The thickness of each spoke portion increases from the first thickness to the second thickness in a direction from the center portion to the perimeter portion, and each recessed portion has the first thickness from the center portion to the perimeter portion. 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 having a front portion including a face portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion. An inner side of the face portion may have a center portion, an outer wall portion at least partially surrounding the center portion, and a plurality of inner wall portions connecting the center portion to the outer wall portion. The inner side of the face portion can further include a plurality of back portion regions with each back portion region being surrounded by a portion of the outer wall portion, the center portion, and adjacent inner wall 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 method of manufacturing a golf club head may include providing a golf club head having a face portion. The method may include determining a reference characteristic time value at a reference location on the face portion, determining a measured characteristic time value at each of a plurality of locations on the face portion, determining a differential characteristic time value at each of the plurality of locations, and altering a face thickness at a location where the differential characteristic time value is nonzero. 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 described herein. In one example, a golf club head includes a body portion with a front opening and a back opening, a face portion closing the front opening, and a back cover portion that closes the back opening and includes at least 50% of the total area of the back portion, a first port, and a second port. A first mass portion and a second mass portion engage the first port and the second port to close the first port and a second port, respectively. The first mass portion and the second mass portion each includes a material with a greater density than the material of the body portion and the material of the back cover 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. A golf club head includes a face portion having an outer face portion surrounding a face opening and a face insert portion coupled to the outer face portion to close the face opening. A front groove and a back groove are located at a front surface and a back surface of the face portion, respectively. The front and back grooves define an inner area portion for striking a golf ball. The front and back grooves are configured to enhance deflection and rebounding of the inner area portion during impact with the golf ball. The front groove has a groove length that is the same or about the same as a groove length of the back groove. Other examples and embodiments may be described and claimed.
