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 hollow body portion defining an interior cavity and a front portion with a front opening, a face portion coupled to the front portion to enclose the interior cavity, a first filler material at least partially filling the interior cavity, a second filler material at least partially filling the interior cavity, and a plate portion inside the interior cavity. The plate portion at least partially separates the first filler material from the second filler material. 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 defining an interior cavity, and a front portion with a front opening;
a face portion coupled to the front portion to enclose the interior cavity;
a first filler material at least partially filling the interior cavity;
a second filler material at least partially filling the interior cavity; and
a plate portion inside the interior cavity,
wherein the plate portion comprises a material having a density different from a density of a material of the hollow body portion,
wherein the plate portion at least partially separates the first filler material from the second filler material, and
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 plate portion fully separates the first filler material from the second filler material.
3. A golf club head as defined in claim 1 , wherein the plate portion comprises a through port extending between the first filler material to the second filler material.
4. A golf club head as defined in claim 1 , wherein the hollow body portion comprises at least one port, and wherein the first filler material is injected into the interior cavity from the at least one port.
5. A golf club head as defined in claim 1 , wherein the hollow body portion comprises at least one port, and wherein the second filler material is injected into the interior cavity from the at least one port.
6. A golf club head as defined in claim 1 , wherein the plate portion is parallel or substantially parallel to the face portion.
7. A golf club head as defined in claim 1 , wherein the at least one different physical property is coefficient of restitution.
8. A golf club head comprising:
a body portion having an interior cavity, and a front portion with a front opening;
a face portion coupled to the front portion to close the interior cavity;
means for at least partially separating the interior cavity into a first interior cavity portion and a second interior cavity portion;
a first filler material at least partially filling the first interior cavity portion; and
a second filler material at least partially filling the second interior cavity portion,
wherein the means for at least partially separating the interior cavity comprises a material having a different density than a density of a material of the body portion, and
wherein a coefficient of restitution of the first filler material is different from a coefficient of restitution of the second filler material.
9. A golf club head as defined in claim 8 , wherein means for at least partially separating the interior cavity comprises a plate portion inside the interior cavity oriented parallel or substantially parallel to the face portion.
10. A golf club head as defined in claim 8 , wherein the body portion comprises at least one port configured to provide access to the first interior cavity portion.
11. A golf club head as defined in claim 8 , wherein the body portion comprises at least one port configured to provide access to the second interior cavity portion.
12. A golf club head as defined in claim 8 , wherein means for at least partially separating the interior cavity comprises means for accessing the second interior cavity portion from the first interior cavity portion.
13. A golf club head as defined in claim 8 further comprising a mass portion coupled to the body portion, wherein a density of a material of the mass portion is greater than a density of a material of the body portion.
14. A golf club comprising:
a shaft having a first end portion and a second end portion;
a grip coupled to the first end portion of the shaft; and
a golf club head coupled to the second end portion of the shaft, the golf club head comprising:
a hollow body portion defining an interior cavity, and a front portion with a front opening;
a face portion coupled to the front portion to enclose the interior cavity;
a first filler material at least partially filling the interior cavity;
a second filler material at least partially filling the interior cavity; and
a plate portion inside the interior cavity,
wherein the plate portion comprises a material having a density different from a density of a material of the hollow body portion of the golf club head,
wherein the plate portion at least partially separates the first filler material from the second filler material, and
wherein the first filler material and the second filler material have different coefficients of restitution.
15. A golf club as defined in claim 14 further comprising at least one mass portion coupled to the hollow body portion, wherein the at least one mass portion comprises a metal having a greater density than a density of a material of the hollow body portion.
16. A golf club as defined in claim 14 , wherein the plate portion comprises a through port extending between the first filler material to the second filler material.
17. A golf club as defined in claim 14 , wherein the hollow body portion comprises at least one port, and wherein the first filler material or the second filler material is injected into the interior cavity from the at least one port.
18. A golf club as defined in claim 14 , wherein the plate portion comprises a material having a density different from a density of a material of the face portion of the golf club head.
19. A golf club as defined in claim 14 , wherein the plate portion is parallel or substantially parallel to the face portion.
