Home appliance including hairline and manufacturing method thereof

1 . A manufacturing method of a home appliance comprising a hairline, the manufacturing method comprises:

forming at least one plating layer on a base material;

processing a transverse hairline on an upper surface of the plating layer by tilting a hairline processing wheel at a predetermined angle; and

forming a coating layer on the hairline,

wherein the forming of the at least one plating layer comprises:

forming a copper plating layer by plating copper (Cu) on the base material;

forming a nickel plating layer by plating nickel (Ni) on the formed copper plating layer; and

forming a chromium plating layer by plating chromium (Cr) on the formed nickel plating layer, and

wherein the chromium layer is processed to be worn by 0.08 to 0.20 μm during the hairline processing.

2 . The manufacturing method according to claim 1 , wherein the tilting angle of the hairline processing wheel is 4° to 10°.

3 . The manufacturing method according to claim 1 , wherein the forming of the plating layer comprises:

plating the copper plating layer to 5 to 30 μm;

plating the nickel plating layer to 5 to 30 μm on an upper surface of the copper plating layer; and

plating the chromium plating layer to 0.30 to 0.80 μm on an upper surface of the nickel plating layer.

4 . The manufacturing method according to claim 1 , wherein the base material is aluminum (Al).

5 . The manufacturing method according to claim 1 , wherein the coating layer is coated using one of acrylic, fluorine, and silane-based paints.

6 . The manufacturing method according to claim 1 , wherein the hairline is formed to form an angle of 87° to 93° with respect to a vertical line which is perpendicular to a short side of the base material.
