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 body portion with a toe portion, a top portion, a sole portion, and a back portion. The back portion may be include a back wall portion. The golf club head may also include a face portion, an interior cavity, at least one weight portion, and at least one port. The interior cavity may be partially or entirely filled with a polymer material. Other examples and embodiments may be described and claimed.

5. A golf club head as defined in claim 1 , wherein the front portion comprises a face portion having a first thickness and a second thickness less than the first thickness.
6. A golf club head as defined in claim 1 , wherein at least one port of the plurality of ports is farther from the heel portion than the toe portion.
7. A golf club head comprising:
a face portion;
a body portion coupled to the face portion, the body portion having a front portion, a toe portion, a top portion, a sole portion, a back portion with a back wall portion, and an interior cavity;
a polymer material injected into the interior cavity through an opening at or proximate to a periphery of the body portion to at least partially structurally support the face portion during impact with a golf ball;
a first set of weight portions being associated with a first total mass, the first set of weight portions including at least one weight portion located on the back wall portion of the back portion;
a second set of weight portions being associated with a second total mass being greater than the first total mass, the second set of weight portions including at least one weight portion located on the back wall portion of the back portion,
wherein at least 50% of the polymer material in the interior cavity is located below a horizontal midplane of the body portion,
wherein the opening is configured to receive a weight portion of the first set of weight portions or a weight portion of the second set of weight portions, and
wherein at least one weight portion of the first set of weight portions or the second set of weight portions comprises a screw configured to be readily removable from the opening to provide access to the interior cavity.
8. A golf club head as defined in claim 7 , wherein at least one weight portion of the first set of weight portions comprises tungsten.
9. A golf club head as defined in claim 7 , wherein at least one weight portion of the second set of weight portions comprises tungsten.
10. A golf club head as defined in claim 7 , wherein the polymer material comprises an elastic polymer material.
11. A golf club head as defined in claim 7 , wherein the face portion comprises a thickness of less than or equal to about 1.9 millimeters (0.075 inch).
12. A golf club head as defined in claim 7 , wherein the face portion comprises a first thickness and a second thickness less than the first thickness.
13. A golf club head as defined in claim 7 further comprising at least another opening located at or below the horizontal midplane.
14. A golf club head comprising:
a first portion made of a first material, and associated with a first mass, the first portion having at least one groove, a first surface, a second surface opposite of the first surface, and a width between the first and second surfaces of less than or equal 1.9 millimeters (0.075 inch), and the first portion configured to impact a golf ball;
a second portion made of a second material, associated with a second mass, and coupled to the first portion, the second portion having an interior cavity, a top portion, a sole portion, a toe portion, a back portion having a back wall portion, and a heel portion having a hosel portion configured to receive a shaft;
a plurality of third portions associated with a third mass located on the back wall portion of the back portion, and coupled to the second portion, at least one portion of the plurality of third portions being made of a third material;
a fourth portion located at a distance from the hosel portion, the fourth portion having an opening configured to receive at least one portion of the plurality of third portions,
wherein the interior cavity is partially or entirely filled from the opening with a fourth material different than the first material or the second material, the fourth material being associated with a fourth mass,
wherein the second mass is greater than the first mass,
wherein the second mass is greater than the third mass,
wherein the second mass is greater than the fourth mass,
wherein at least one portion of the plurality of third portions is located at or below a horizontal midplane of the second portion, and
wherein at least one portion of the plurality of third portions comprises a screw configured to be readily removable from the opening to provide access to the interior cavity.
