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.

Claims (6)

1. A method for surface treating a golf club head, comprising:

(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, said outer surface being divided into a working and a non-working area, said depression unit being formed in said working area;

(b) filling the depression unit with a shielding material and covering said non-working area with a covering material, the covering material adjoining the outer surface of the golf club head, all of the covering material being spaced away from the depression unit along the outer surface of the club head; 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 said non-working area so as to form the working area into sandblasted and non-sandblasted regions that differ in gloss intensity.

2. The method as in claim 1 , wherein the shielding material is selected from the group consisting of waxes, silicones, resins, gypsum, paints, and plastics.

3. The method as claimed in claim 1 , wherein the shielding material is a wax having a melting point ranging from 40 to 60° C.
