After CNC machining, aluminum materials typically require surface treatment to improve product performance and appearance. Anodizing is the most common method, not only improving corrosion resistance but also offering a variety of colors for aesthetic appeal and durability.
Sandblasting eliminates machining marks, resulting in a more uniform and delicate surface and enhancing the subsequent anodizing effect. Powder coating and electrophoresis form a protective layer, improving wear resistance and oxidation resistance.
For precision electronic products, processes such as wire drawing and polishing can also be used to enhance the product's grade. Different products have different requirements for appearance and performance; therefore, the appropriate surface treatment method should be selected based on the specific application scenario to meet customer needs.
