What surface treatment processes are there for aluminum profile shells
The surface treatment process of aluminum profile shells is a key step to ensure the appearance, durability and corrosion resistance of the product. The following are some common surface treatment processes for aluminum profile shells: # Aluminum profile shell #
Anodizing: This is a technology that forms a hard aluminum oxide film on the surface of aluminum through an electrochemical process. Anodizing not only enhances the corrosion resistance and wear resistance of the shell, but also provides a rich variety of color options through dyeing, making the product appearance diverse and attractive.
Electrophoretic Coating (Electrophoretic coating) : This technology deposits paint onto the surface of aluminum alloy through an electrophoretic process, providing a smooth and uniform coating. The surface after electrophoretic coating has good adhesion and chemical resistance, and can also provide a certain degree of aesthetic appeal.
Powder Coating: Powder coating involves electrostatically adsorbing dry powder coatings onto the surface of aluminum alloys and then subjecting them to high-temperature baking to melt the powder and form a uniform coating. This method is bright in color, environmentally friendly and durable, and has a very good effect on improving the appearance and durability of the shell.
Sandblasting (Sandblasting) : Sandblasting treatment involves cleaning the surface of aluminum alloys with fine sand particles sprayed at high speed to remove impurities, oxide layers or old coatings. At the same time, it can roughen the surface and enhance the adhesion of the coating. This approach is typically used as a pretreatment step for other surface treatment methods.
Brushing: Brushing is the process of treating the surface of aluminum profiles with mechanical brushes or grinding tools to create an effect with longitudinal or transverse grinding marks. The surface treatment effect of brushing can be matte or mirror-like, with a certain degree of gloss. Brushing treatment can improve the appearance and texture of aluminum profiles, enhancing their decorative and aesthetic appeal.
Polishing: Mechanical polishing is a method that makes the surface of aluminum profile equipment shells smooth and bright through mechanical grinding and polishing. This processing method can enhance the smoothness and appearance quality of the product.
High-gloss milling/High-gloss cutting: Utilizing high-precision CNC processing equipment to cut some detailed parts of aluminum or aluminum alloy material parts, creating local high-gloss areas on the product surface and increasing the brightness variation.
Transparent coating: Clear varnish finish is a transparent protective layer applied to the surface of aluminum. This finish can enhance the natural appearance of aluminium while providing anti-corrosion protection.
The selection of these surface treatment processes depends on factors such as the required appearance, function, and the environmental conditions in which the shell is used. Together, they ensure the high performance and aesthetic appeal of the aluminum profile shell.
