Example Embodiment
[0019] Example 1
[0020] A processing method for surface-carved multi-color aluminum profiles, and the process steps are as follows.
[0021] (1) Surface carving of aluminum profile: Because the shape of the aluminum profile is very irregular, a wooden base mold must be made before the aluminum profile is carved. The aluminum profile is flattened and fixed on the aluminum profile, and the shape and depth (height The data of) is input into the CNC engraving machine, the plane to be carved is carved, the butt joints of the pattern and the burrs of the pattern are ground off and flattened with a fine grinding machine. The depth of the pattern is 1 / 5-1 / 4 of the thickness of the aluminum profile. Because the thickness of the general aluminum profile is 1-4mm, the depth of the embossed pattern is generally 0.2-1mm.
[0022] (2) First coloring: Coloring the surface of aluminum profile with anodized film.
[0023] (3) The second coloring: ① Use a computer-based engraving machine for artisti...
Example Embodiment
[0024] Example 2
[0025] The paint ratio of this embodiment is calculated by weight percentage: 45 for metal paint, 16, toner 16, polyurethane curing agent 22, and thinner 17.
[0026] After painting the pattern part, spray a layer of transparent varnish on the surface to prevent the toner from falling off. Otherwise, the processing method of the surface-carved multi-color aluminum profile is the same as in Example 1.
Example Embodiment
[0027] Example 3
[0028] The paint ratio of this embodiment is calculated by weight percentage: 50 for metallic paint, 12 for color paste, 18 for polyurethane curing agent, and 20 for thinner. The processing method of the other surface-carved multi-color aluminum profiles is the same as that of the first embodiment.
