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 face portion, a toe portion, a top portion, a sole portion, and a back portion. The golf club head may include an interior cavity. Other examples and embodiments may be described and claimed.

Claims

1. A golf club head comprising:

a body portion having a body height, 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 front surface, a back surface, a plurality of grooves on the front surface extending between the toe portion and the heel portion, a substantially uniform first thickness of less than 1.5 millimeters (0.06 inch) in the face portion between the grooves and extending between the front and back surfaces, and a reinforcement section of a plurality of reinforcement sections projecting out of the back surface, the reinforcement section being aligned with at least one of the grooves of the plurality of grooves and having a length extending in the same direction as a length of the at least one groove, a second thickness in the face portion defined by a distance between a bottom surface of at least one of the grooves and an outer surface of the reinforcement section being less than 1.5 millimeters (0.06 inch); and

an interior cavity extending between the top and sole portions and between the face and back portions, the interior cavity having a cavity height,

wherein the interior cavity is at least 50% filled with an elastic polymer material configured to provide structural integrity to the face portion.

2. A golf club head as defined in claim 1, wherein the interior cavity comprises a cavity being at least 50% filled with at least one of a thermoplastic elastomer material or a thermoplastic polyurethane material.

3. A golf club head as defined in claim 1, wherein the cavity height comprises a height being at least 50% of the body height.

4. A golf club head as defined in claim 1, wherein the cavity height comprises a height being greater than 70% and less than 85% of the body height.

5. A golf club head as defined in claim 1, wherein the elastic polymer material comprises a thermoplastic elastomer material injection molded into the interior cavity.

6. A golf club head as defined in claim 1, wherein each reinforcement section of the plurality of reinforcement sections is aligned with a corresponding groove of the plurality of grooves and having a length extending in the same direction as a length of the corresponding groove.

7. A golf club head as defined in claim 1, wherein the second thickness is less than or equal to the first thickness.

8. A golf club head as defined in claim 1, wherein the face portion comprises a loft angle between fifteen degrees and seventy-five degrees.

9. A golf club head comprising:

a body portion having a body height, 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 front surface, a back surface, a plurality of grooves on the front surface extending between the toe portion and the heel portion, a first uniform thickness of less than 1.5 millimeters (0.06 inch) between the grooves and extending between the front and back surfaces, a second uniform thickness extending between the back surface and a bottom surface of each groove of the plurality of grooves, and a reinforcement section of a plurality of reinforcement sections projecting out of the back surface, the reinforcement section being aligned with at least one of the grooves of the plurality of grooves and having a length extending in the same direction as a length of the at least one groove, a second thickness in the face portion defined by a distance between a bottom surface of at least one of the grooves and an outer surface of the reinforcement section being less than 1.5 millimeters (0.06 inch); and

an interior cavity extending between the top and sole portions and between the face and back portions, the interior cavity having a cavity height,

wherein the interior cavity is partially or entirely filled with an elastic polymer material, and

wherein a thickness of the face portion between the top portion and the groove that is adjacent to the top portion and between the sole portion and the groove that is adjacent to the sole portion is the same as the first uniform thickness.

10. A golf club head as defined in claim 9, wherein the interior cavity comprises a cavity being partially or entirely filled with at least one of a thermoplastic elastomer material or a thermoplastic polyurethane material.

11. A golf club head as defined in claim 9, wherein the cavity height comprises a height being at least 50% of the body height.

12. A golf club head as defined in claim 9, wherein the cavity height comprises a height being greater than 70% and less than 85% of the body height.

13. A golf club head as defined in claim 9, wherein each reinforcement section of the plurality of reinforcement sections is aligned with a corresponding groove of the plurality of grooves and having a length extending in the same direction as a length of the corresponding groove.

14. A golf club head as defined in claim 9, wherein the wherein the elastic polymer material comprises a thermoplastic elastomer material injection molded into the interior cavity.
