Golf club heads and methods to manufacture golf club heads
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 includes a recessed opening between a front opening and a back wall portion, a front plate portion coupled to the recessed opening to enclose a first interior cavity in the golf club head between the front plate portion and the back wall portion, a face portion coupled to a front portion to enclose a second interior cavity between the face portion and the front plate portion, a first filler material at least partially filling the first interior cavity, and a second filler material at least partially filling the second interior cavity. The first filler material and the second filler material have at least one different physical property. Other examples and embodiments may be described and claimed.
1. A golf club head comprising:
a hollow body portion, a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front portion with a front opening, a back portion with a back wall portion, a top portion with a top portion edge, and a sole portion with a sole portion edge;
a recessed opening between the front opening and the back wall portion;
a front plate portion coupled to the hollow body portion at the recessed opening to enclose a first interior cavity in the hollow body portion between the front plate portion and the back wall portion;
a face portion coupled to the front portion to enclose a second interior cavity between the face portion and the front plate portion;
a first filler material at least partially filling the first interior cavity; and
a second filler material at least partially filling the second interior cavity,
wherein the first filler material and the second filler material have at least one different physical property.
2. A golf club head as defined in claim 1 , wherein the recessed opening is defined by a perimeter ledge portion configured to receive a perimeter portion of the front plate portion.
3. A golf club head as defined in claim 1 , wherein the front plate portion includes a pocket portion defining a portion of the second interior cavity.
4. A golf club head as defined in claim 1 , wherein the hollow body portion comprises at least one port configured to provide access to the first interior cavity.
5. A golf club head as defined in claim 1 , wherein the hollow body portion comprises at least one port configured to provide access to the second interior cavity.
6. A golf club head as defined in claim 1 , wherein the front plate portion comprises at least one port configured to provide access to the second interior cavity from the first interior cavity.
7. A golf club head as defined in claim 1 , wherein the at least one different physical property is elasticity.
8. A golf club head comprising:
a hollow body portion having a front portion with a front opening defined by a perimeter edge portion and a back portion with a back wall portion;
a ledge portion between the front opening and the back wall portion;
a plate portion coupled to the ledge portion to enclose a first interior cavity of the hollow body portion between the plate portion and the back wall portion;
a face portion coupled to the perimeter edge portion to enclose a second interior cavity of the hollow body portion between the face portion and the plate portion;
a first filler material at least partially filling the first interior cavity; and
a second filler material at least partially filling the second interior cavity,
wherein a thickness of the plate portion is greater than or equal to 0.01 inch (0.254 mm) and less than or equal to 0.06 inch (1.524 mm).
9. A golf club head as defined in claim 8 , wherein the plate portion includes a pocket portion defining a portion of the second interior cavity.
10. A golf club head as defined in claim 8 , wherein the hollow body portion comprises at least one port configured to provide access to the first interior cavity.
11. A golf club head as defined in claim 8 , wherein the hollow body portion comprises at least one port configured to provide access to the second interior cavity.
12. A golf club head as defined in claim 8 , wherein the plate portion comprises at least one port configured to provide access to the second interior cavity from the first interior cavity.
13. A golf club head as defined in claim 8 , wherein the first filler material and the second filler material have at least one different physical property.
14. A method comprising:
providing a hollow body portion, a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front portion with a front opening, a back portion with a back wall portion, a top portion with a top portion edge, a sole portion with a sole portion edge, and a recessed opening between the front opening and the back wall portion;
providing a face portion;
providing a front plate portion smaller than the face portion and having an average thickness less than an average thickness of the face portion;
coupling the front plate portion to the hollow body portion at the recessed opening to enclose a first interior cavity in the hollow body portion between the front plate portion and the back wall portion;
coupling the face portion to the front portion to enclose a second interior cavity between the face portion and the front plate portion;
filling the first interior cavity with a first filler material; and
filling the second interior cavity with a second filler material different from the first filler material.
15. A method as defined in claim 14 , wherein the recessed opening is defined by a perimeter ledge portion configured to receive a perimeter portion of the front plate portion.
16. A method as defined in claim 14 , wherein the front plate portion includes a pocket portion defining a portion of the second interior cavity.
17. A method as defined in claim 14 , wherein the hollow body portion comprises at least one port configured to provide access to the first interior cavity.
18. A method as defined in claim 14 , wherein the hollow body portion comprises at least one port configured to provide access to the second interior cavity.
19. A method as defined in claim 14 , wherein the front plate portion comprises at least one port configured to provide access to the second interior cavity.
20. A method as defined in claim 14 , wherein the first filler material and the second filler material have different elasticities.
