1. A method comprising:
- forming a plurality of weight portions made of a first material;
forming a body portion of a golf club head made of a second material, the body portion having a toe portion, a top portion, a sole portion, a back portion, a front portion, an interior cavity extending between the top and sole portions and between the front and back portions, and an exterior port connected to the interior cavity;
forming a plurality of exterior weight ports on the back portion of the body portion, each of the exterior weight ports being associated with a port diameter and configured to receive at least one weight portion of the plurality of weight portions, the plurality of exterior weight ports having;
a first set of exterior weight ports formed along the periphery of the back portion at or proximate to at least one of the top portion or the toe portion, anda second set of exterior weight ports formed along the periphery of the back portion at or proximate to at least one of the sole portion or the toe portion,wherein any two adjacent exterior weight ports of the first set of exterior weight ports are separated by less than the port diameter, and any two adjacent exterior weight ports of the second set of exterior weight ports are separated by less than the port diameter; and
injecting an elastic polymer material into the interior cavity from the exterior port.

15. A method comprising:
-
forming a hollow body portion of a golf club head, the hollow body portion having a toe portion, a top portion, a sole portion, a back portion, and a front portion having a face portion; a first set of weight portions coupled to the hollow body portion at or proximate to a top-and-toe transition region between the top portion and the toe portion, the first set of weight portions being associated with a first total mass; a second set of weight portions coupled to the hollow body portion at or proximate to a sole-and-toe transition region between the sole portion and the toe portion, the second set of weight portions being associated with a second total mass and located below a horizontal midplane of the golf club head, wherein the first total mass is less than the second total mass; and forming an interior cavity comprising an elastic polymer material between the front portion and the back portion, the elastic polymer material being configured to at least partially absorb impact on the face portion. - View Dependent Claims (16, 17, 18, 19, 20)
