Abstract
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 heel portion, a top portion, a sole portion, a back portion, and a front portion having a face portion. The golf club head may include an interior cavity. The interior cavity is at least partially filled with an elastic polymer material. A bonding portion bonds the elastic polymer material to the face portion. Other examples and embodiments may be described and claimed.
Claims20
A golf club head comprising:
- a body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion with a plurality of weight portions, and a front portion having a face portion with a thickness extending between a front surface and a back surface, the thickness being less than or equal to 1.5 millimeters (0.06 inch);
- an interior cavity extending between the top and sole portions and between the face and back portions;
- a bonding portion bonded to the back surface of the face portion;
- and
- an elastic polymer material injection molded in the interior cavity to structurally support the face portion during impact with a golf ball,
- wherein the elastic polymer material is bonded to the bonding portion;
- wherein a greater number of weight portions of the plurality of weight portions are located on the back portion below a horizontal midplane of the body portion than above the horizontal midplane.
A golf club head comprising:
- a body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion with a plurality of weight portions, and a front portion having a face portion with a front surface and a back surface;
- an interior cavity extending between the top and sole portions and between the face and back portions;
- a bonding portion bonded to the back surface of the face portion;
- an elastic polymer material injection molded in the interior cavity to structurally support the face portion during impact with a golf ball;
- wherein the bonding portion is bonded to the face portion before injection molding the elastic polymer material in the interior cavity;
- wherein the elastic polymer material is bonded to the bonding portion after being injection molded in the interior cavity, and
- wherein a greater number of weight portions of the plurality of weight portions are located on the back portion below a horizontal midplane of the body portion than above the horizontal midplane.
A golf club head comprising:
- a body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion with a plurality of weight portions, and a front portion having a face portion with a front surface and a back surface, a thickness of the face portion extending between the front and back surfaces being less than or equal to 1.5 millimeters (0.06 inch);
- an interior cavity extending between the top and sole portions and between the face and back portions;
- a bonding portion having an initial cure state and a final cure state with a different bonding configuration than the initial cure state, the bonding portion configured to bond to the back surface of the face portion at the initial cure state;
- and
- an elastic polymer material injection molded in the interior cavity to structurally support the face portion during impact with a golf ball, the bonding portion configured to bond to the elastic polymer material at the final cure state,
- wherein a greater number of weight portions of the plurality of weight portions are closer to the toe portion than the heel portion.
