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 face portion. The body portion may comprise stainless steel having a density between 7.0 and 8.3 grams per cubic centimeter and a tensile strength between 600 million and 800 million Newtons per square meter. The golf club head may include an interior cavity and a plurality of weight portions. 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 body portion having a toe portion, a heel portion, a top portion, a sole portion, and a front portion having a face portion with a front surface and a back surface, the face portion having a thickness between the front and back surfaces of less than or equal to 1.905 millimeters (0.075 inch);

a first weight portion having a first mass;

a second weight portion having a second mass greater than the first mass, the second weight portion located at or below a horizontal midplane of the body portion;

an interior cavity extending between the top and sole portions;

at least one port on the body portion, the at least one port configured to receive the first weight portion;

an elastic polymer material in the interior cavity, and

wherein the body portion comprises stainless steel having a density of between 7.0 grams per cubic centimeter and 8.3 grams per cubic centimeter, and a tensile strength between 600 million Newtons per square meter (600 Megapascals) and 800 million Newtons per square meter (800 Megapascals).

2. A golf club head as defined in claim 1, wherein the body portion comprises stainless steel having a yield strength between 500 Newtons per square meter (500 Megapascals) and 700 million Newtons per square meter (700 Megapascals).

3. A golf club head as defined in claim 1, wherein the body portion comprises stainless steel having a hardness of between 10 Rockwell Hardness in the C scale (HRC) and 40 HRC.

4. A golf club head as defined in claim 1, wherein the body portion comprises stainless steel having an elongation of between 5% and 40%.

5. A golf club head as defined in claim 1, wherein the at least one port is connected to the interior cavity, and wherein the interior cavity is filled with the elastic polymer material from the at least one port.

6. A golf club head as defined in claim 1, wherein the second weight portion is larger than the first weight portion.

7. A golf club head comprising:

a body portion having a toe portion, a heel portion, a top portion, a sole portion, and a front portion having a face portion with a front surface and a back surface, the face portion having a thickness between the front and back surfaces of less than or equal to 1.905 millimeters (0.075 inch);

an interior cavity extending between the top and sole portions;

an elastic polymer material in the interior cavity; and

at least one weight portion located at or below a horizontal midplane of the body portion,

wherein the body portion comprises stainless steel material having a density of between 7.0 grams per cubic centimeter and 8.3 grams per cubic centimeter, and a tensile strength between 600 million Newtons per square meter (600 Megapascals) and 800 million Newtons per square meter (800 Megapascals).

8. A golf club head as defined in claim 7, wherein the body portion comprises stainless steel having a yield strength between 500 million Newtons per square meter (500 Megapascals) and 700 million Newtons per square meter (700 Megapascals).

9. A golf club head as defined in claim 7, wherein the body portion comprises stainless steel having a hardness of between 10 Rockwell Hardness in the C scale (HRC) and 40 HRC.

10. A golf club head as defined in claim 7, wherein the body portion comprises stainless steel having an elongation of between 5% and 40%.

11. A golf club head as defined in claim 7, wherein the at least one weight portion is integral with the body portion.

12. A golf club head as defined in claim 7, wherein the at least one weight portion comprises a material having a greater density than the density of the stainless steel material of the body portion.

13. A golf club head as defined in claim 7, wherein the elastic polymer material is injected into the interior cavity from a port on the body portion, and wherein the port is farther from the heel portion than the at least one weight portion.

14. A golf club head comprising:

a body portion having an interior cavity, at least one port connected to the interior cavity, a toe portion, a heel portion, a top portion, a sole portion, and a front portion having a face portion with a front surface and a back surface;

a polymer material in the interior cavity configured to partially or entirely fill the interior cavity by injection molding from the at least one port, the polymer material configured to at least partially structurally support the face portion during impact of the face portion with a golf ball;

wherein the body portion comprises stainless steel having a density of between 7.0 grams per cubic centimeter and 8.3 grams per cubic centimeter, and a tensile strength between 600 million Newtons per square meter (600 Megapascals) and 800 million Newtons per square meter (800 Megapascals), and

wherein the face portion has a first thickness between the front and back surfaces of less than or equal to 1.905 millimeters (0.075 inch) and second thickness having a greater thickness than the first thickness.

15. A golf club head as defined in claim 14, wherein the body portion comprises a yield strength between 500 million Newtons per square meter (500 Megapascals) and 700 million Newtons per square meter (700 Megapascals).

16. A golf club head as defined in claim 14, wherein the body portion comprises stainless steel having a hardness of between 10 Rockwell Hardness in the C scale (HRC) and 40 HRC.

17. A golf club head as defined in claim 14, wherein the body portion comprises stainless steel having an elongation of between 5% and 40%.

18. A golf club head as defined in claim 14 further comprising at least one weight portion located at or below a horizontal midplane of the body portion.

19. A golf club head as defined in claim 14 further comprising at least one weight portion located closer to the heel portion than the at least one port.

20. A golf club head as defined in claim 14 further comprising a first weight portion and a second weight portion, wherein the second weight portion is larger and has a greater density than the first weight portion.
