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, a front portion, and an interior cavity at least partially filled with an elastic polymer material. The golf club head may include a first set of weight portions and a second set of weight portions on the body portion. Other examples and embodiments may be described and claimed.

Claims

1. A 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 thickness extending between a front surface and a back surface, the thickness being less than or equal to 1.5 millimeters (0.06 inch);

an interior cavity extending between the top and sole portions and between the face and back portions, wherein the interior cavity is at least partially filled with an elastic polymer material;

a first set of weight portions including at least one first weight portion located on the back portion above a horizontal midplane of the body portion;

a second set of weight portions including at least one second weight portion located on the back portion below the horizontal midplane;

wherein a total number of first weight portions in the first set of weight portions is greater than a total number of second weight portions in the second set of weight portions, and

a mass of the at least one first weight portion is less than a mass of the at least one second weight portion.

2. A golf club head as defined in claim 1, wherein the first set of weight portions includes two or more first weight portions, and wherein the second set of weight portions includes two or more second weight portion.

3. A golf club head as defined in claim 1, wherein each first weight portion of the first set of weight portions has a different shape than each second weight portion of the second set of weight portions.

4. A golf club head as defined in claim 1, wherein the interior cavity is entirely filled with the elastic polymer material.

5. A golf club head as defined in claim 1, wherein the face portion comprises a substantially uniform thickness from at or proximate to the top portion to at or proximate to the sole portion.

6. A golf club head as defined in claim 1 further comprising a first set of ports including at least one first port and a second set of ports including at least one second port located on the back portion, the at least one first port of the first set of ports configured to receive the at least one first weight portion of the first set of weight portions or the at least one second weight portion of the second set of weight portions, and the at least one second port of the second set of ports configured to receive the at least one first weight portion of the first set of weight portions or the at least one second weight portion of the second set of weight portions.

7. A golf club head as defined in claim 1 further comprising:

two or more first ports located on the back portion above the horizontal midplane, each port of the two or more first ports being configured to receive a first weight portion of the first set of weight portions; and

a second port located on the back portion below the horizontal midplane, the second port being configured to receive the at least one second weight portion of the second set of weight portions.

8. A golf club head as defined in claim 1, wherein each first weight portion of the first set of weight portions and each second weight portion of the second set of weight portions is located nearer to the toe portion than to the heel portion.

9. A 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 thickness extending between a front surface and a back surface, the thickness being less than or equal to 1.5 millimeters (0.06 inch);

an interior cavity extending between the top and sole portions and between the face and back portions, wherein the interior cavity is at least partially filled with an elastic polymer material;

a first set of ports including two or more first ports located on the back portion above a horizontal midplane of the body portion, each of the first ports of the first set of ports having a substantially similar first port diameter as an adjacent first port and being separated by less than the first port diameter from the adjacent first port; and

a second set of ports including at least one second port located on the back portion below the horizontal midplane,

wherein a total number of first ports in the first set of ports is greater than a total number of second ports in the second set of ports.

10. A golf club head as defined in claim 9 further comprising two or more first weight portions and at least one second weight portion, wherein each first port of the first set of ports is configured to receive a first weight portion of the two or more weight portions and each port of the second set of ports is configured to receive the at least one second weight portion.

11. A golf club head as defined in claim 9 further comprising two or more first weight portions and at least one second weight portion, wherein each first port of the first set of ports is configured to receive a first weight portion of the two or more first weight portions and each second port of the second set of ports is configured to receive the at least one second weight portion, and wherein a total mass of the two or more first weight portions is less than a total mass of the at least one second weight portion.

12. A golf club head as defined in claim 9, wherein the interior cavity is entirely filled with the elastic polymer material.

13. A golf club head as defined in claim 9, wherein the face portion comprises a substantially uniform thickness from at or proximate to the top portion to at or proximate to the sole portion.

14. A golf club head as defined in claim 9, wherein the second set of ports includes two or more second ports.

15. A golf club head as defined in claim 9 further comprising two or more weight portions, each first port of the first set of ports being configured to receive a weight portion of the two or more weight portions, and wherein the at least one second port of the second set of ports is configured to receive a weight portion of the two or more weight portions.

16. A golf club head comprising:

a plurality of weight portions;

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;

an interior cavity extending between the top and sole portions and between the face and back portions, wherein the interior cavity is at least partially filled with an elastic polymer material;

a first set of ports including two or more first ports located on the back portion above a horizontal midplane of the body portion, each of the first ports of the first set of ports having a substantially similar first port diameter as an adjacent first port and being separated by less than the first port diameter from the adjacent first port; and

a second set of ports including at least one second port located on the back portion below the horizontal midplane,

wherein each first port of the first set of ports is configured to receive a weight portion of the plurality of weight portions, and each second port of the second set of ports is configured to receive a weight portion of the plurality of weight portions, and

wherein a total number of first ports in the first set of ports is greater than a total number of second ports in the second set of ports.

17. A golf club head as defined in claim 16, wherein a total mass of the weight portions received within the first set of ports is less than a total mass of the weight portions received within the second set of ports.

18. A golf club head as defined in claim 16, wherein the face portion has a thickness extending between a front surface and a back surface, the thickness being less than or equal to 1.5 millimeters (0.06 inch).

19. A golf club head as defined in claim 16, wherein the second set of ports includes two or more second ports.
