Anodized aluminum nameplates are high-performance identification products made from aluminum as the base material. A dense oxide film is formed on the surface through an anodizing process, combined with steps such as dyeing and sealing. This process combines decorative and functional properties, and is widely used in equipment nameplates, electronic products, automobiles, and other fields.
Suitable for nameplates requiring high durability and multiple colors, the process is as follows:
Slicing: Cut aluminum plates to size.
Mechanical Polishing → Chemical/Electrochemical Polishing: Obtain a bright, clean surface.
Anodizing: Generate a porous alumina film by passing an electric current through an acidic electrolyte (such as sulfuric acid).
Coloring: Apply a base color through dye adsorption or electrolytic coloring.
Sealing: Seal the pores of the oxide film to enhance corrosion resistance.
Screen Printing: Print text/patterns using specialized inks.
Removal: Locally remove the oxide film to prepare for secondary oxidation.
Second Oxidation + Coloring + Sealing: Separate the text/pattern from the base color.
Mechanical Polishing, Cutting, and Stamping: Complete the finished product.
