Thickness: 5-25μm Colors: Various Materials: Aluminum, Ti, Mg ### Plating Metal coating process that deposits a thin layer of metal onto the surface, providing enhanced corrosion resistance, conductivity, and aesthetic appeal. Types: Zn, Ni, Cr, Au, Ag Thickness: 2-50μm Materials: Most Metals ### Powder Coating Dry finishing process that applies a free-flowing dry powder electrostatically and cures under heat, creating a hard, durable finish. Thickness: 50-150μm Colors: Unlimited Materials: Metal, Plastic ### Polishing Abrasive process that smooths and shines surfaces to achieve mirror-like finishes, removing scratches and imperfections for enhanced aesthetics. Roughness: Ra 0.1-0.8μm Finish: Mirror Materials: All Metals ### Bead Blasting Surface treatment that propels abrasive media at high velocity to clean, smooth, or texture surfaces, creating uniform matte finishes. Media: Glass, Alumina, Steel Finish: Matte Materials: All Metals ### Electropolishing Electrochemical process that removes material from the surface, improving micro-finish, reducing surface roughness, and enhancing corrosion resistance. Roughness: Ra 0.2-0.8μm Removal: 10-50μm Materials: Stainless Steel ## Technical Specifications Detailed capabilities and quality standards ### Equipment Capabilities Part Size 1000×1000mm Coating Thickness 5-150μm Temperature Control ±2°C Surface Roughness Ra 0.1-3.2μm Processing Capacity 5000+ parts/day ### Quality Standards #### ISO 9001:2015 Quality management system certification #### Salt Spray Testing Corrosion resistance verification #### Thickness Measurement Coating thickness verification #### Visual Inspection Surface quality assessment ## Industries We Serve Trusted by leading companies across various industries ### Automotive Engine components, chassis parts, decorative finishes ### Medical Surgical instruments, implants, medical devices ### Electronics Connectors, housings, heat sinks ### Aerospace Aircraft components, fasteners, structural parts ## Frequently Asked Questions Common questions about our finishing services We offer a comprehensive range of surface finishing processes including anodizing, plating (zinc, nickel, chrome, gold, silver), powder coating, polishing, bead blasting, and electropolishing.
