Anodizing Die-Cast Parts: Transformative Finishing Solutions

We've pioneered a solution that allows anodizing for die-cast parts, a breakthrough in surface finishing. This technique offers enhanced corrosion resistance and aesthetic appeal, expanding the application scope for die-cast components in various industries.

What is EternalModel Die-Casting Parts Anodizing Services

Anodizing of die-cast parts, typically referring to aluminum alloys or other non-ferrous metal die-castings, is an electrochemical surface treatment process designed to enhance the corrosion resistance, wear resistance, and aesthetic appeal of the parts. Anodizing is also known as anodization or hard anodizing.

During the anodizing process, the die-cast part is placed in a solution containing a specific electrolyte (such as sulfuric acid) and serves as the anode. When an electric current passes through the solution, a layer of aluminum oxide (Al₂O₃) forms on the surface of the part. This oxide layer is very hard and dense, offering effective protection against environmental degradation.

Key characteristics of anodizing include:

  1. Increased Corrosion Resistance: The oxide layer resists corrosion from most acidic and basic substances.

  2. Enhanced Surface Hardness: The oxide film increases surface hardness, thereby improving wear resistance.

  3. Improved Aesthetics: Anodizing can add a variety of colors to die-cast parts, enhancing their visual appeal and marketability.

  4. Electrical Insulation: The oxide film provides electrical insulation, making it suitable for applications that require electrical isolation.

Anodizing not only improves the performance and appearance of products but also extends their application range, commonly seen in automotive parts, electronic devices, and architectural decoration.
