Surface treatment method for aluminum alloy window handle

Electrophoretic spraying is a common surface treatment method that applies voltage at the anode and cathode to move charged coating ions to the cathode and form insoluble substances that deposit on the surface of the workpiece, forming a dense resin film. This method can improve corrosion resistance, make the surface very bright, and have a mirror effect.

Anodizing is the process of forming an oxide film on aluminum products (anodes) by applying an external current under specific electrolyte and process conditions. This oxide film not only improves the handle and wear resistance of the aluminum alloy, but also has excellent heat dissipation and super strong metallic texture, with uniform and consistent colors that do not fade.

Wood grain transfer printing is a technology that transfers the wood grain effect to the surface of aluminum alloy, making the surface of aluminum alloy have the texture and aesthetics of wood, while maintaining the durability of aluminum alloy.

Sandblasting treatment is mainly used to overcome and conceal some defects in aluminum alloys during mechanical processing, as well as to meet customers' special requirements for product appearance, which can present different sensations, such as the rough texture of frosted glass.

Polishing treatment is used to reduce the surface roughness of the metal, making the surface of the aluminum alloy bright and smooth, approaching the mirror effect of stainless steel, and improving the aesthetics and smoothness of the product.

Suitable processing methods can be selected based on specific usage environments and aesthetic requirements. For example, electrophoretic spraying and anodizing treatment can improve the corrosion resistance and hardness of aluminum alloys, making them suitable for applications that require high durability; Wood grain transfer printing and sandblasting are more suitable for applications that pursue aesthetics and personalization
