Three-dimensional finishing method for aluminum (etching method)
After anodizing aluminum, cover the parts of the surface that you want to remain as a three-dimensional image with a corrosion-resistant protective film, and then immerse it in a solution that dissolves aluminum. The unprotected unwanted parts will be removed (etching process, see figure), resulting in the desired three-dimensional image. Since the dissolved area reveals the raw aluminum, further anodizing can be applied to this part, and if necessary, it can also be dyed. In this way, three-dimensional images or text can be obtained, and by combining the differences in gloss and matte finishes due to the pre-treatment of the image and the base material, along with dyeing, decorative reliefs and nameplates with rich design can be achieved.
