Abstract

An insert for a golf club head, wherein the insert includes a generally planar base surface and a maximum thickness, T max , measured perpendicular to the base surface. The insert further includes a first component comprising a non-metallic material, and a second component coupled to the first component and comprising a continuous, formed metal sheet having a thickness between 0.01 mm and 3.0 mm, the second component extending a maximum distance, D, in a direction perpendicular to the base surface, that is no less than 6 mm. The insert is configured such that a ratio D/T max is no less than 0.50.

First claim

What is claimed is:

1. A method of forming an insert for attachment to a golf club head comprising:
(a) forming a metal component by stamping a metal sheet, having a first end and a second end opposite the first end, by actuating a punch relative to a die such that, during the actuation of the punch, the first end is constrained and the second end is unconstrained, the metal sheet having a thickness between 0.01 mm and 3.0 mm; and
(b) securing the metal component to a non-metallic component to form a multi-component insert defining a generally planar base surface, the metal component extending a maximum distance, D, in a direction perpendicular to the base surface, that is no less than 6 mm, the multi-component insert comprising a maximum thickness, T max , measured perpendicular to the base surface, that is no less than 7 mm, wherein D/T max is no less than 0.50, wherein the metal component includes a pair of sloped segments disposed on opposite sides of an intermediate segment, the intermediate segment being parallel to the base surface, the pair of sloped segments collectively extending the maximum distance D in the direction perpendicular to the base surface.

2. The method of claim 1 , wherein the punch is complementary in shape to the die.

3. The method of claim 1 , wherein the non-metallic component comprises a polymeric material.

4. The method of claim 1 , further comprising securing a two-sided adhesive tape to the multi-component insert.

5. The method of claim 1 , wherein the metal component comprises aluminum or aluminum alloy.

6. The method of claim 1 , wherein the maximum distance, D, is no less than 8 mm.

7. The method of claim 1 , wherein the metal component comprises a flange, extending generally parallel to the base surface, and a sloped wall, in communication with the flange, extending outward relative to the base surface.

8. The method of claim 7 , wherein the sloped wall comprises a step formation.

9. A method of forming an insert for attachment to a golf club head comprising:
(a) forming a metal component by stamping a metal sheet that is of a thickness between 0.01 mm and 3.0 mm, having a first end and a second end opposite the first end, by actuating a punch relative to a die such that, during the actuation of the punch, the first end is constrained and the second end is unconstrained; and
(b) securing the metal component to a non-metallic component to form a multi-component insert defining a generally planar base surface and a maximum thickness, T max , measured perpendicular to the base surface, that is no less than 7 mm, such that the metal component comprises a flange, extending generally parallel to the base surface, and a sloped wall, in communication with the flange, extending outward relative to the base surface, the metal component extending a maximum distance D, in a direction perpendicular to the base surface, such that a ratio D/T max is no less than 0.50, wherein the metal component includes a pair of sloped segments disposed on opposite sides of an intermediate segment, the intermediate segment being parallel to the base surface, the pair of sloped segments collectively extending the maximum distance D in the direction perpendicular to the base surface.

10. The method of claim 9 , wherein the punch is complementary in shape to the die.

11. The method of claim 9 , wherein the non-metallic component comprises a polymeric material.

12. The method of claim 9 , further comprising securing a two-sided adhesive tape to the multi-component insert.

13. The method of claim 9 , wherein the metal component comprises aluminum or aluminum alloy.

14. The method of claim 9 , wherein, in a direction perpendicular to the base surface, the metallic component extending a maximum distance, D, that is no less than 6 mm.

15. The method of claim 14 , wherein the maximum distance, D, is no less than 8 mm.

16. The method of claim 9 , wherein the metal sheet comprises a material having a percent elongation at fracture within the range of about 8% to about 12%.
