During forming, dimensional accuracy is maintained via precision tooling and process controls. Any deformation processes are followed by stress-relief heat treatments to minimize warping or residual stresses that could compromise anodizing uniformity.

Assembly and Pre-Treatment

For complex assemblies, components are joined through welding, riveting, or adhesive bonding before the anodizing process. Prior to anodizing, parts are subjected to cleaning and etching steps, including alkaline degreasing and acid pickling, to ensure the surface is free of oils, oxides, and corrosion products. A critical step here is etching or brightening to achieve a uniform surface finish, which directly influences the aesthetic and functional qualities of the final anodized layer.

Anodizing Process

The core of manufacturing involves electrochemical anodizing, where aluminum components are submerged in electrolyte solutions (commonly sulfuric acid). The process parameters—voltage, current density, temperature, and duration—are precisely controlled to produce a consistent oxide layer thickness, typically between 5-25 microns. Thicker layers (hard anodizing) are used for wear-resistant applications, while thinner layers are suitable for decorative purposes. Post-anodizing sealing, often through hot water or chemical solutions, closes the pores, enhancing corrosion resistance and enabling dyeing if required.

Finishing and Quality Control

Final finishing includes dyeing, if color customization is needed, followed by sealing. Additional surface treatments such as polishing or brushing may be applied for aesthetic purposes. Throughout this process, critical control points ensure that surface integrity, color uniformity, and layer thickness meet specified standards.
