Abstract

A method for surface treating a golf club head, includes: (a) forming a depression unit in the golf club head, the depression unit being indented inwardly from an outer surface of the golf club head, the outer surface being divided into a working area and a non-working area, the depression unit being formed in the working area; (b) filling the depression unit with a shielding material and covering the non-working area with a covering material; and (c) sandblasting the golf club head after step (b) and removing subsequently the shielding material from the depression unit and the covering material from the non-working area so as to form the working area into sandblasted and non-sandblasted regions that differ in gloss intensity.

First claim

What is claimed is:

1. A method for manufacturing an apparatus, the method comprising:
plating the apparatus;
applying an anti-corrosion treatment to the apparatus;
after plating the apparatus and applying the anti-corrosion treatment, at least partially filling a depression area located on an outer surface of the apparatus with a shielding material; and
sandblasting the outer surface of the apparatus including the depression area filled with the shielding material to create a non-sandblasted region coinciding with the location of the depression area and a sandblasted region distinct from the location of the depression area.

2. The method of claim 1 , further comprising polishing the apparatus prior to the filling of the depression area with the shielding material.

3. A method for manufacturing a golf club head, the method comprising:
forming a depression area using one of: a carving technique and a molding technique;
applying an anti-corrosion treatment to the apparatus;
after applying the anti-corrosion treatment, at least partially filling the depression area located on the outer surface of the golf club head with a shielding material; and
sandblasting the outer surface of the golf club head including the depression area filled with the shielding material to create a non-sandblasted region coinciding with the location of the depression area and a sandblasted region distinct from the location of the depression area.

4. The method of claim 3 , further comprising polishing the golf club head prior to the filling of the depression area with the shielding material.

5. The method of claim 3 , further comprising plating the golf club head prior to the filling of the depression area with the shielding material.

6. A method for manufacturing a golf club head, the method comprising:
applying an anti-corrosion treatment to the apparatus;
after applying the anti-corrosion treatment, at least partially filling a depression area located on the outer surface of the golf club head with a shielding material, the depression area located adjacent to a non-working area;
covering the non-working area with a covering material;
sandblasting the golf club head including the depression area filled with the shielding material to create a first non-sandblasted region coinciding with the location of the depression area, a second non-sandblasted region coinciding with the location of the non-working area and a sandblasted region distinct from both the location of the depression area and the location of the non-working area.

7. The method of claim 6 , further comprising polishing the club head prior to the filling of the depression area with the shielding material.

8. The method of claim 6 , further comprising plating the golf club head prior to the filling of the depression area with the shielding material.

9. The method of claim 6 , wherein the covering includes wrapping a plastic sheet around the non-working area.

10. The method of claim 6 , wherein filling the depression area further includes: melting shielding wax to fill the depression area and subsequently cooling the shielding wax to create a solid shielding wax.

11. The method of claim 6 , further comprising removing the shielding material using dichloromethane.

12. The method of claim 6 , further comprising removing the shielding material using an ultrasound cleaning equipment.
