Arc Anodizing Service For Die Castings

Preparation and Cleaning

The first step in arc anodizing involves cleaning the die-cast part thoroughly to remove any surface contaminants, oils, or debris. Proper cleaning ensures that the part is ready for anodizing, promoting optimal adhesion and uniformity of the anodic layer.

Arc Anodizing Process

The part is immersed in an electrolyte solution and subjected to a high-voltage electrical current. The process forms a thick, durable oxide layer on the part’s surface, enhancing corrosion resistance, wear resistance, and mechanical strength.

Coloring (Optional)

After anodizing, the oxide layer can be colored through a dyeing process. This optional step allows for vibrant, custom finishes that are highly durable, ensuring the parts maintain their aesthetic appeal while preserving strength and functionality.

Sealing

The anodized part is then sealed to close the pores of the oxide layer, typically through a hot water or chemical sealing process. This step locks in the protective layer, improving corrosion resistance and ensuring long-term durability in harsh environments.
