Golf club heads and methods to manufacture golf club heads
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 hollow body portion having a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, a top portion, a first interior cavity portion, and a second interior cavity portion. The first interior cavity portion may be at least partially filled with a polymer material. Other examples and embodiments may be described and claimed.

a second interior cavity portion,
wherein the first interior cavity portion extends to the face portion and the second interior cavity portion,
wherein the first interior cavity portion is at least partially filled with a polymer material, and
wherein the polymer material is coupled to the face portion.
2. A golf club head as defined in claim 1 , wherein the first interior cavity portion further comprises:
a third width below the second width,
wherein the second width is greater than the third width.
3. A golf club head as defined in claim 1 further comprising a port on the body portion connected to the first interior cavity portion, wherein the port is configured to receive the polymer material.
4. A golf club head as defined in claim 1 further comprising a plurality of mass portions on the bottom portion located closer to the front portion than the rear portion, wherein the first interior cavity portion at least partially extends over the plurality of mass portions.
5. A golf club head as defined in claim 1 further comprising a first set of mass portions closer to the toe portion than the heel portion, and a second set of mass portions closer to the heel portion than the toe portion.
6. A golf club head as defined in claim 1 , wherein the first interior cavity portion and the second interior cavity portion are separated by a cavity wall portion, and wherein the cavity wall portion is less than or equal to 1.0 inch (25.4 millimeters) from the face portion.
7. A golf club head as defined in claim 1 , wherein the first interior cavity portion is associated with a first volume, wherein the second interior cavity portion is associated with a second volume, and wherein the first volume is less than or equal to 50% of the second volume.
8. A golf club head comprising:
a body portion having a toe portion, a heel portion, a top portion, a bottom portion, a rear portion, and a front portion;
a face portion having a thickness of less than or equal to 0.075 inch (1.905 millimeters);
a cavity wall portion in the body portion extending to the toe portion and the heel portion and extending to the top portion and the bottom portion, the cavity wall portion comprising:
a first wall portion extending from the top portion toward the bottom portion;
a second wall portion extending from the first wall portion toward the rear portion and the bottom portion; and
a third wall portion extending from the second wall portion to the bottom portion;
a first interior cavity portion extending to the cavity wall portion and the face portion; and
a second interior cavity portion extending to the cavity wall portion and the rear portion,
wherein the first interior cavity portion is at least 50% filled with a polymer material, and wherein the polymer material is coupled to the face portion.
9. A golf club head as defined in claim 8 further comprising a port on the body portion connected to the first interior cavity portion, wherein the port is configured to receive the polymer material.
10. A golf club head as defined in claim 8 further comprising a plurality of mass portions on the bottom portion located closer to the front portion than the rear portion, wherein the first interior cavity portion at least partially extends over the plurality of mass portions.
11. A golf club head as defined in claim 8 further comprising a first set of mass portions closer to the toe portion than the heel portion, and a second set of mass portions closer to the heel portion than the toe portion.
12. A golf club head as defined in claim 8 , wherein the cavity wall portion is less than or equal to 1.0 inch (25.4 millimeters) from the face portion.
13. A golf club head as defined in claim 8 , wherein the first interior cavity portion is associated with a first volume, wherein the second interior cavity portion is associated with a second volume, and wherein the first volume is less than or equal to 50% of the second volume.
14. A golf club head comprising:
a body portion having a toe portion, a heel portion, a top portion, a bottom portion, a rear portion, and a front portion;
a face portion having a thickness of less than or equal to 0.075 inch (1.905 millimeters);
a cavity wall portion located in the body portion less than or equal to 1.0 inch (25.4 millimeters) from the face portion, the cavity wall portion extending to the toe portion, the heel portion, the top portion and the bottom portion;
a first interior cavity portion extending to the cavity wall portion and the face portion, the first interior cavity portion comprising an enlarged cavity portion below a neutral axis, the enlarged cavity portion having a depth greater than a maximum depth of the first interior cavity portion above the neutral axis; and
a second interior cavity portion extending to the cavity wall portion and the rear portion,
wherein the first interior cavity portion is associated with a first volume, the second interior cavity portion is associated with a second volume, and the first volume is less than or equal to 50% of the second volume, and
wherein the first interior cavity portion is at least partially filled with a polymer material.
15. A golf club head as defined in claim 14 , further comprising a port on the body portion connected to the first interior cavity portion, wherein the port is configured to receive the polymer material.
16. A golf club head as defined in claim 14 further comprising a plurality of mass portions on the bottom portion located closer to the front portion than the rear portion, wherein the first interior cavity portion at least partially extends over the plurality of mass portions.
