Surface Treatment

Surface treatment is a process that uses the four core values of protection, strengthening, beautification, and functionalization to artificially form a surface layer on the base material, with different mechanical, physical, and chemical properties compared to the base material. The purpose of surface treatment is to meet the product’s requirements for corrosion resistance, wear resistance, decoration, or other special functions.

We offer a wide range of surface treatment services, including anodizing, plating, electrophoresis, baking paint, sandblasting, polishing, and passivation, to meet our clients’ needs for product appearance, performance, and durability. Whether enhancing aesthetics, improving durability, or fulfilling specific functional requirements, we provide professional and customized surface treatment solutions.
