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.
| Surface Finish | Key Benefits | Typical Applications | Performance Tests | Environmental Compliance |
|---|---|---|---|---|
| Anodizing | Corrosion resistance, decorative, hardness increase | Aluminum housings, heat sinks, electronics | Salt spray, hardness, adhesion | ✔ RoHS/REACH compliant |
| Electroplating (Ni/Cr/Zn) | Conductivity, appearance, corrosion resistance | Connectors, casings, auto parts | Salt spray, electrical resistance, coating thickness | ✔ Depends on process |
| E-coating | Uniform coating, strong adhesion, corrosion resistance | Auto parts, steel hardware, complex parts | Adhesion, impact, salt spray, film thickness | ✔ Water-based options RoHS compliant |
| Brushed Finish | Aesthetic, deburring, consistent texture | Stainless panels, consumer electronics | Visual inspection, roughness | ✔ No chemical residues |
| Polishing | High gloss, defect removal | Decorative parts, medical devices, reflectors | Gloss, roughness, cleanliness | ✔ Mechanical polishing is eco-friendly |
| Sandblasting | Oxide removal, surface texture uniformity | Pre-coating, aluminum profiles, tools | Surface roughness, adhesion | ✔ Eco media optional |
| Coating (Powder/Liquid) | Color variety, abrasion & corrosion resistance | Appliance housings, equipment parts, hardware | Adhesion, abrasion, salt spray, impact | ✔ Powder coating eco-friendly |
| Passivation | Corrosion resistance, no visual change | Stainless parts, medical/military parts | Salt spray, passivation film test | ✔ RoHS/REACH |
