Method for surface treating a golf club head
View Patent ↗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.
1. A method of manufacturing a golf club head, the method comprising:
forming a depression unit in an area of the golf club head;
filling the depression unit with a shielding material;
sandblasting the golf club head including the area with the depression unit filled with the shielding material such that the shielding material protects the depression unit from the sandblasting and the sandblasting forms a sandblasted region; and
removing the shielding material from the depression unit, resulting in a non-sandblasted region.
2. The method of claim 1 , farther comprising polishing the golf club head prior to formation of the depression unit.
3. The method of claim 1 , further comprising polishing the golf club head after formation of the depression unit but prior to filling the depression unit with shielding material.
4. The method of claim 1 , further comprising plating the golf club head prior to formation of the depression unit.
5. The method of claim 1 , further comprising plating the golf club head after formation of the depression unit but prior to filling the depression unit with shielding material.
6. The method of claim 1 , further comprising applying an anti-corrosion treatment to the golf club head prior to formation of the depression unit.
7. The method of claim 1 , further comprising applying an anti-corrosion treatment to the golf club head after formation of the depression unit but prior to filling the depression unit with shielding material.
8. A method of manufacturing a golf club head, the method comprising:
forming a depression unit on a rear surface of the golf club head;
filling the depression unit with a shielding material;
sandblasting the golf club head including the area with the depression unit filled with the shielding material such that the shielding material protects the depression unit from the sandblasting and the sandblasting forms a sandblasted region; and
removing the shielding material from the depression unit, resulting in a non-sandblasted region.
9. The method of claim 8 , further comprising polishing the golf club head prior to formation of the depression unit.
10. The method of claim 8 , further comprising polishing the golf club head after formation of the depression unit but prior to filling the depression unit with shielding material.
11. The method of claim 8 , further comprising plating the golf club head prior to formation of the depression unit.
12. The method of claim 8 , further comprising plating the golf club head after formation of the depression unit but prior to filling the depression unit with shielding material.
13. The method of claim 8 , further comprising applying an anti-corrosion treatment to the golf club head prior to formation of the depression unit.
14. The method of claim 8 , further comprising applying an anti-corrosion treatment to the golf club head after formation of the depression unit but prior to filling the depression unit with shielding material.
15. A method of manufacturing a golf club head, the method comprising:
forming a depression unit within a working area of the golf club head, the working area being positioned adjacent a non-working area;
protecting a first region corresponding to the depression unit from sandblasting via a first material of protection;
sandblasting the golf club head including the working area; and
removing the first material of protection, resulting in a sandblasted region surrounding the first region, wherein the sandblasting operation creates a variance in surface appearance between the sandblasted region and the first region.
16. The method of claim 15 , wherein protecting the first region from sandblasting includes filling the depression unit with the first material of protection.
17. The method of claim 15 , wherein the first material of protection is selected from a group consisting of wax, silicon, resin, gypsum, paint and plastic.
18. The method of manufacturing of claim 15 , further comprising protecting a second region within the non-working area from the sandblasting operation via a second material of protection.
19. The method of claim 18 , wherein protecting the second region from the sandblasting operation includes wrapping the second region with the second material of protection.
20. The method of claim 18 , wherein the second material of protection is a plastic.
