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 face portion, a toe portion, a top portion, a sole portion, and a back portion with at least one weight portion. The golf club head may include an interior cavity. The golf club head may include face markings on the face portion that include a first set of markings extending between the toe portion and the heel portion and a second set of markings extending between the top portion and the sole portion. 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, a back portion with a plurality of ports each including one of a plurality of weight portions having a mass, and a face portion to engage a golf ball;

a plurality of grooves formed on the face portion and extending lengthwise between the toe portion and the heel portion, the plurality of grooves being substantially parallel to each other with each of the plurality of grooves having a groove width and a groove depth; and

a plurality of substantially rectangularly recessed markings formed on the face portion, each of the plurality of markings having a marking width and a marking depth, the plurality of markings including at least one first set of markings extending in a line lengthwise between the toe portion and the heel portion and at least one second set of markings extending lengthwise between the top portion and the sole portion along a line perpendicular to the at least one first set of markings and the plurality of grooves,

wherein the at least one first set of markings and the at least one second set of markings form a substantially grid-like pattern on the face portion,

wherein the groove depth is greater than the marking depth, and

wherein more than 50 percent of the mass of the plurality of weight portions is located on the back portion below a horizontal midplane of the body portion, and at least one of the plurality of ports including at least one of the weight portions of the plurality of weight portions is located on the back portion above the horizontal midplane and closer to the toe portion than to the heel portion.

2. A golf club head as defined in claim 1, wherein the groove width is greater than the marking width.

3. A golf club head as defined in claim 1, wherein the plurality of markings extends to cover substantially the entire face portion.

4. A golf club head as defined in claim 1, wherein the at least one first set of markings comprises at least two first markings formed between two adjacent grooves of the plurality of grooves.

5. A golf club head as defined in claim 1, wherein the marking width comprises a width of about 0.020 inch or the marking depth comprises a depth of about 0.001 inch.

6. A golf club head as defined in claim 1, wherein the body portion is a hollow body portion at least partially filled with an elastic polymer material.

7. A golf club head as defined in claim 1, wherein the at least one first set of markings extend in a line substantially parallel to the plurality of grooves.

8. A golf club head as defined in claim 1, wherein at least a portion of the plurality of markings do not intersect with any of the plurality of grooves or any other of the plurality of markings.

9. A golf club head as defined in claim 1, wherein at least one of the plurality of markings comprises one or more markings formed by at least one of a milling process or a laser etching process.

10. 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 ports each including one of a plurality of weight portions below a horizontal midplane of the body portion and at least one port including at least one weight portion on the back portion above the horizontal midplane of the body portion, and a face portion having an impact area to engage a golf ball;

at least one groove associated with a groove width and a groove depth and formed in the impact area, the at least one groove extending lengthwise between the toe portion and the heel portion; and

a plurality of substantially rectangularly recessed markings formed on the impact area, each of the plurality of markings having a marking width and a marking depth, the plurality of markings including at least one first set of markings extending along a line generally in the same direction as the at least one groove and at least one second set of markings extending lengthwise in a direction along a line generally transverse to the at least one groove and the at least one first set of markings,

wherein the at least one first set of markings and the at least one second set of markings form a substantially grid-like pattern on the face portion,

wherein the groove depth is greater than the marking depth, and

wherein more than 50 percent of a combined mass of the plurality of weight portions on the back portion is located below the horizontal midplane and the at least one weight portion on the back portion above the horizontal midplane is located closer to the toe portion than to the heel portion.

11. A golf club head as defined in claim 10, wherein the groove width is greater than the marking width.

12. A golf club head as defined in claim 10, wherein the plurality of markings extends to cover substantially the entire face portion.

13. A golf club head as defined in claim 10, wherein the at least one first set of markings comprises at least two markings formed between two adjacent grooves of the at least one groove.

14. A golf club head as defined in claim 10, wherein the marking width comprises a width of about 0.020 inch or the marking depth comprises a depth of about 0.001 inch.

15. A golf club head as defined in claim 10, wherein the body portion is a hollow body portion at least partially filled with an elastic polymer material.

16. 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 ports each including one of a plurality of weight portions located below a horizontal midplane of the body portion and at least one port including at least one weight portion located on the back portion above the horizontal midplane of the body portion, and a face portion to engage a golf ball;

at least one groove associated with a groove width and a groove depth, the at least one groove formed in an impact area of the face portion and extending lengthwise between the toe portion and the heel portion; and

a plurality of substantially rectangularly recessed markings associated with a marking width and a marking depth and formed in the impact area of the face portion, the plurality of markings having at least one first set of markings and at least one second set of markings, the at least one first set of markings extending lengthwise between the toe portion and the heel portion and along a line that is substantially parallel to the at least one groove, the at least one second set of markings extending lengthwise between the top portion and the sole portion along a line that is substantially perpendicular to the at least one groove and the at least one first set of markings,
