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, and a substantially uniform thickness extending between the front and back surfaces of less than 1.5 millimeters (0.06 inch) throughout the entire face portion, and a reinforcement section on the back surface aligned with at least one of the grooves of the plurality of grooves and extending lengthwise with the at least one groove; 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 the face portion comprises a plurality of reinforcement sections on the back surface, each reinforcement section being aligned with a corresponding groove of the plurality of grooves and extending lengthwise with the corresponding groove.

7. A golf club head as defined in claim 1, wherein the face portion comprises a second thickness extending between a bottom of the at least one groove and the reinforcement section, 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 extending between the front and back surfaces of less than 1.5 millimeters (0.06 inch), 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 on the back surface aligned with at least one of the grooves of the plurality of grooves and extending lengthwise with the at least one groove; 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 the first uniform thickness is adjacent to each groove of the plurality of grooves and located at or proximate to the top and sole portions.

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 the face portion comprises a plurality of reinforcement sections on the back surface, each reinforcement section being aligned with a corresponding groove of the plurality of grooves and extending lengthwise with the corresponding groove.

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

15. An iron-type golf club head comprising:

a body portion having 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 a plurality of grooves extending between the toe portion and the heel portion with each groove having a depth, a first thickness extending between a front surface and a back surface, a second thickness extending between a bottom surface of at least one groove of the plurality of grooves and the back surface, and a third thickness extending at a periphery of the face portion; and

an interior cavity extending between the top and sole portions and between the face and back portions, the interior cavity being filled with an elastic polymer material,

wherein the first thickness comprises a substantially uniform thickness of less than 1.5 millimeters (0.06 inch), and

wherein the third thickness comprises a thickness greater than the first thickness.

16. An iron-type golf club head as defined in claim 15, wherein the interior cavity comprises a cavity filled with at least one of a thermoplastic elastomer material or a thermoplastic polyurethane material.

17. An iron-type golf club head as defined in claim 15, wherein the first thickness comprises a thickness less than or equal to a sum of the depth of the at least one groove and the second thickness.

18. An iron-type golf club head as defined in claim 15, wherein the interior cavity comprises a cavity height being greater than 70% and less than 85% of a body height associated with the body portion.

19. An iron-type golf club head as defined in claim 15, wherein the second thickness comprises a thickness greater than or equal to the first thickness.

20. An iron-type golf club head as defined in claim 15, wherein the face portion comprises a chamfer portion at the periphery of the face portion.
