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. The golf club head may include an interior cavity. The interior cavity may be filled with an elastic polymer material. Other examples and embodiments may be described and claimed.

Claims

1. A golf club head comprising:

a face portion having a thickness of less than or equal to 1.9 millimeters (0.075 inch);

a body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion, and an interior cavity at least 50% filled with a polymer material; and

at least one mass portion coupled to the body portion at a location below a horizontal midplane of the golf club head, the mass portion having a first end and a second end farther from the face portion than the first end,

wherein a first portion of the polymer material in the interior cavity is between the first end of the mass portion and the face portion and a second portion of the polymer material in the interior cavity is located above the mass portion and farther from the face portion than the first end of the mass portion,

wherein the maximum width of the interior cavity extends between the face portion and the back portion and is below the horizontal midplane, and

wherein the back portion comprises a back wall portion with an upper back wall portion, a lower back wall portion, and a ledge portion between the upper back wall portion and the lower back wall portion and extending outward from the upper back wall portion, and wherein a width of the ledge portion is greater than a width of the body portion above the horizontal midplane.

2. A golf club head as defined in claim 1 further comprising a bonding portion configured to attach the polymer material to the face portion.

3. A golf club head as defined in claim 1, wherein the mass portion is closer to the toe portion than the heel portion.

4. A golf club head as defined in claim 1 further comprising at least one port connected to the interior cavity.

5. A golf club head comprising:

a face portion;

a body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion, and an interior cavity, the back portion including a back wall portion with an upper back wall portion, a lower back wall portion, and a ledge portion between the upper back wall portion and the lower back wall portion and extending outward from the upper back wall portion;

at least one port located closer to the toe portion than the heel portion and connected to the interior cavity; and

at least one mass portion located closer to the toe portion than the heel portion and located between the at least one port and the heel portion,

wherein the interior cavity is partially or entirely filled with a polymer material from the at least one port,

wherein a width of the interior cavity above the at least one mass portion and below the ledge portion is greater than a width of the ledge portion and greater than a width of the interior cavity between the at least one mass portion and the face portion,

wherein the width of the ledge portion is greater than a width of the interior cavity above the ledge portion, and

wherein a portion of the at least one mass portion is closer to the face portion than a portion of the polymer material in the interior cavity.

6. A golf club head as defined in claim 5, wherein the width of the interior cavity above the at least one mass portion and below the ledge portion is greater than 50% of the greatest width of the body portion.

7. A golf club head as defined in claim 5, wherein the at least one port is located at or below a horizontal midplane of the golf club head.

8. A golf club head as defined in claim 5, wherein the at least one mass portion is located below a horizontal midplane of the golf club head.

9. A golf club head as defined in claim 5, wherein the at least one mass portion is closer to the sole portion than the at least one port.

10. A golf club head as defined in claim 5, wherein the at least one mass portion comprises a screw.

11. A golf club head as defined in claim 5, wherein the face portion comprises a thickness of less than or equal to 1.9 millimeters (0.075 inch).
