In one example, a golf club head includes a body portion having an interior cavity, a ledge portion extending outward from a back wall of the body portion, a filler material comprising a rubber compound in the interior cavity, a first set of mass portions that is closer to a toe portion edge of the body portion than to a heel portion edge of the body portion, and a second set of mass portions that is closer to the heel portion edge than to the toe portion edge. A face portion is coupled to the body portion to enclose the interior cavity and includes at least one back groove located proximate to a perimeter edge of the face 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 heady may include a body portion having an interior cavity with a front opening, a face portion coupled to the front opening to close the interior cavity, a plurality of back groove portions on a back surface of the face portion, a mass portion coupled to the body portion, a polymer filler material in the interior cavity, and a face support portion coupled to the back surface of the face portion. Each groove portion of the plurality of back groove portions is located between the face support portion and a perimeter edge of the face 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 an interior cavity, a front portion, a rear portion, a toe portion, a heel portion, a sole portion, and a top portion. A face portion may be coupled to the front portion and may include a front surface having a plurality of grooves with each groove extending in a first direction, and a back surface having a plurality of channels with each channel having a length and a width being substantially smaller than the length. A filler material may at least partially fill the interior cavity. The length of at least one channel of the plurality of channels may extend in a second direction different from the first direction. Each channel may be at least partially filled with the filler material and may be configured to engage the filler material to adhere the filler material to the back surface of the face 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 may include a body portion with an interior cavity and face portion, and weight portion and a wall portion on a bottom portion of the body portion extending into the interior cavity. A polymer material may be in the interior cavity located between and coupled to the wall portion and the weight portion. The wall portion may be farther from the face portion than to the weight portion. The weight portion may be closer to a front portion than to a rear portion of the body portion. A distance between the weight portion and the face portion may be greater than a distance between the weight portion and the wall portion. Other examples and embodiments may be described and claimed.
