Cleaning: An Essential Step in Anodizing Pre-Treatment for Raw Aluminum Preparation

Cleaning removes any contaminants from the surface of the aluminum, such as dirt, grease, oils, oxides, or other foreign materials. By removing these contaminants the quality of the anodized finish is improved.

Brightening & Etching: An Essential Process for Smoothing and Eliminating Imperfections

The brightening and etching processes are integral to anodizing pre-treatment as they play a vital role in effectively smoothing surface roughness, eliminating imperfections, and controlling the final finish of the aluminum surface.

Anodizing: Creating an Anodic Film Using Aluminum as a Base

After pre-treatment, an anodic film is built from the aluminum itself. An electrical current is passed through an electrolyte bath in which the aluminum has been immersed. The anodic thickness can be tightly controlled and is hard and porous for accepting coloring dyes.

Coloring: Enhancing Aluminum with Endless Possibilities of Colors & Hues

Anodizing coloring is a process that adds color to anodized aluminum. Methods like absorptive dye coloring and electrolytic coloring offer a vast range of vibrant hues, providing endless possibilities.

Sealing: Preserving Colors and Enhancing Durability of Anodized Aluminum

Sealing is the process of closing the pores in the anodic film, effectively locking in the colors and creating a surface that is highly resistant to staining, abrasion, and color degradation. This sealing step enhances the durability and longevity of the anodized aluminum, ensuring that the colors remain vibrant and intact over time. It also provides additional protection against external factors such as moisture, chemicals, and UV radiation, further enhancing the overall performance and appearance of the anodized aluminum.
