Abstract

A manufacturing method for a golf club head. The method includes the steps of: casting a cast body provided with a recession thereon; cutting the cast body to form with at least one cut opening in the recession on the golf club head; adhering a carbon-fiber plate to the recession to seal the cut opening; defining a buffer groove between the carbon-fiber plate and the cast body; and filling with an elastic material into the buffer groove; processing the cast body to an end product.

Claims

1. A manufacturing method for a golf club head, comprising steps of:

casting a body formed with a recession, said recession integrally provided with a bottom part which supports the recession to avoid deformation;

cutting the body to form at least one opening in the recession on the golf club head and remaining at least one support rib shaped to a desired configuration in the recession, said support rib running across a crown portion of the body for reinforcing the entire structure of the crown portion;

inserting a cover plate into the recession to seal the opening, said support rib abutting against the cover plate for precise positioning in the recession;

defining a buffer groove between the cover plate and the body, and filling with an elastic material into the buffer groove; and

precision-machining the body to accomplish an end product of the golf club head.

4. The manufacturing method as defined in claim 1, wherein the recession is provided with the support rib which is integrally connected to an inner edge of the recession.

5. The manufacturing method as defined in claim 1, wherein the cut opening is processed with a laser beam cutting machine, a plasma arc cutting machine or a water-jet cutting machine.

6. The manufacturing method as defined in claim 1, wherein the recession is further provided with a stepped portion adapted to accommodate the cover plate.

7. The manufacturing method as defined in claim 1, wherein the cover plate is adhered to the recession by adhesive.

8. The manufacturing method as defined in claim 1, wherein the elastic material is selected from the group consisting of thermoplastic, rubber, high polymer and PU filler.

9. The manufacturing method as defined in claim 1, wherein the cover plate is a carbon-fiber plate which is prefabricated.

10. The manufacturing method as defined in claim 1, wherein the cover plate is made of light metal, high polymer plastic or high strength glass fiber.

2. (Canceled)

3. (Canceled)

11. A golf club head comprising:

a body including a striking plate, and further provided with at least one recession and a support rib integrally formed therein, said support rib shaped to a desired configuration running across a crown portion of the body for reinforcing the entire structure of the crown portion;

at least one cover plate being inserted into the recession to thereby form a buffer groove between an outer periphery of the cover plate and an inner periphery of the recession, said support rib abutting against the cover plate for precise positioning in the recession; and

an elastic material being filled within the buffer groove.

12. The golf club head as defined in claim 11, wherein the recession is further provided with a stepped portion adapted to accommodate the cover plate.

13. The golf club head as defined in claim 12, wherein the cover plate is adhered to the recession by adhesive.

14. The golf club head as defined in claim 11, wherein the elastic material is selected from the group consisting of thermoplastic, rubber, high polymer and PU filler.

15. The golf club head as defined in claim 11, wherein the cover plate is a carbon-fiber plate which is prefabricated.

16. The gold club head as defined in claim 11, wherein the cover plate is made of light metal, high polymer plastic or high strength glass fiber.
