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 includes providing a body portion having a front portion with a front opening. A front pocket portion is welded to the front portion to close the front opening and form a first cavity. A polymer insert is positioned within the front pocket, the polymer insert occupying less than a total available space within the front pocket portion. A face portion is welded to the front pocket portion to close the front pocket portion and form a second cavity having a volume less than a volume of the first cavity. Other examples and embodiments may be described and claimed.

Claims (41)

1. A method of assembling a golf club head, the method comprising:

providing a body portion comprising a front portion, a rear portion, a toe portion, a heel portion, a top portion, a bottom portion, an interior cavity, and a front opening at the front portion;

joining a front pocket portion to the front portion to close the front opening;

positioning a polymer insert at a central location within the front pocket portion;

injecting a filler material around the polymer insert to at least partially fill a space within the front pocket portion that is unoccupied by the polymer insert; and

joining a face portion to the front pocket portion to close the front pocket portion and define a face cavity containing the polymer insert and the filler material, the face cavity located forward of the interior cavity of the body portion,

wherein the face portion and the front pocket portion compress the polymer insert, and

wherein the front pocket portion is made from a material that is different from a material of the body portion.

2. A method of assembling a golf club head as defined in claim 1 , wherein the filler material is injected into the front pocket portion prior to joining the face portion to the front pocket portion.

3. A method of assembling a golf club head as defined in claim 1 , wherein the filler material is injected into the front pocket portion after joining the face portion to the front pocket portion.

4. A method of assembling a golf club head as defined in claim 1 , wherein the filler material is made from a material having a different hardness than a material of the polymer insert.

5. A method of assembling a golf club head as defined in claim 1 , wherein the face portion is made from a material that is different from the material of the front pocket portion, and wherein the material of the face portion has a higher yield strength than a yield strength of the material of the front pocket portion.

6. A method of assembling a golf club head as defined in claim 5 , wherein the material of the face portion has a yield strength that is at least 40% higher than the yield strength of the material of the front pocket portion.

7. A method of assembling a golf club head as defined in claim 1 , wherein the golf club head has a club head volume greater than or equal to 300 cubic centimeters.

8. A method of manufacturing a golf club head, the method comprising:

providing a body portion comprising a front portion with a front opening;

forming a first cavity by joining a front pocket portion to the front portion to enclose the front opening, the front pocket portion being recessed in a club-inward direction;

positioning a polymer insert within the front pocket portion;

forming a second cavity by joining a face portion to the front pocket portion to enclose the front pocket portion and compress the polymer insert; and

providing a filler material within the second cavity to at least partially fill a cavity space unoccupied by the polymer insert,

wherein the polymer insert contacts a rear surface of the face portion and a rearmost inner surface of the front pocket portion,

wherein the face portion is made from a material that is different from a material of the front pocket portion, and

wherein the material of the face portion has a higher yield strength than a yield strength of the material of the front pocket portion.

9. A method of manufacturing a golf club head as defined in claim 8 , wherein the second cavity has a depth greater than or equal to 0.030 inch and less than or equal to 0.110 inch, the depth measured in a front-to-rear direction of the golf club head.

10. A method of manufacturing a golf club head as defined in claim 8 , wherein the filler material occupies at least 50% of the second cavity.

11. A method of manufacturing a golf club head as defined in claim 8 , wherein the filler material is made from a material having a different hardness than a material of the polymer insert.

12. A method of manufacturing a golf club head as defined in claim 8 , wherein a thickness of the front pocket portion is less than a thickness of the face portion.

13. A method of manufacturing a golf club head as defined in claim 8 , wherein the material of the front pocket portion is the same as a material of the body portion.

14. A method of manufacturing a golf club head as defined in claim 8 , wherein the material of the face portion has a yield strength that is at least 40% higher than the yield strength of the material of the front pocket portion.

15. A method of manufacturing a golf club head, the method comprising:

providing a body portion comprising a front portion with a front opening;

welding a front pocket portion to the front portion to close the front opening and form a first cavity;

positioning a polymer insert within the front pocket portion, the polymer insert occupying less than a total available space within the front pocket portion; and

welding a face portion to the front pocket portion to close the front pocket portion and form a second cavity having a volume less than a volume of the first cavity,

wherein the face portion is made from a material that is different from a material of the front pocket portion, and

wherein the material of the face portion has a higher density than the material of the front pocket portion.

16. A method of manufacturing a golf club head as defined in claim 15 , wherein the golf club head has a club head volume greater than or equal to 300 cubic centimeters.

17. A method of manufacturing a golf club head as defined in claim 15 , wherein the material of the front pocket portion is different from a material of the body portion.

18. A method of manufacturing a golf club head as defined in claim 15 , wherein the material of the face portion has a higher yield strength than the material of the front pocket portion.

19. A method of manufacturing a golf club head as defined in claim 18 , wherein the material of the face portion has a yield strength that is at least 40% higher than a yield strength of the material of the front pocket portion.

20. A method of manufacturing a golf club head as defined in claim 15 , further comprising providing a filler material within the second cavity to at least partially fill a cavity space unoccupied by the polymer insert.
