Abstract (en)

[origin: EP2586894A1] The method comprises preparing (1) a surface of an aluminum metal profile for an anodization bath, depositing (2) a coating layer containing a powder substance on the surface of profile on which a pattern is to be formed, drying (3) the coating layer, performing chemical staining on the profile, moving (5) the coating layer, using a laser beam, corresponding to the pattern to be formed on the surface of profile to sinter the powder substance on the profile, and cleaning (6) the surface of profile to remove the coating layer, immersing the profile in the bath at a high temperature. The method comprises preparing (1) a surface of an aluminum metal profile for an anodization bath, depositing (2) a coating layer containing a powder substance on the surface of profile on which a pattern is to be formed, drying (3) the coating layer, performing chemical staining on the profile, moving (5) the coating layer, using a laser beam, corresponding to the pattern to be formed on the surface of profile to sinter the powder substance on the profile, cleaning (6) the surface of profile to remove the coating layer, immersing the profile in the bath at a high temperature for a duration of 2-10 minutes to form an anodic oxidation layer on the surface of profile, which is in contact with the bath, and stabilizing the anodic oxidation layer. The powder substance is mixed with water, and comprises a mineral powder such as a ceramic powder. The laser beam is perpendicular to the surface of profile comprising the pattern. An independent claim is included for an aluminum metal profile.
