We provide professional PVC dip‑coating service. A seamless, tough PVC protective layer is formed on metal parts, featuring anti‑corrosion, insulation, non‑slip and wear‑resistant performance. Custom colors and coating thickness available for mass production.
Know More
Professional sheet metal repair and surface finishing services. We perform shaping correction and defect repair for various sheet‑metal parts, supported by surface processes including grinding, spraying and anti‑rust treatment. The finished products are smooth, aesthetic, corrosion‑resistant and durable. Custom processing and bulk delivery are available.
Know More
Professional metal degreasing surface treatment service. It removes oil, grease and release agents from workpieces for a thoroughly clean substrate, improving adhesion for subsequent spraying, dip‑coating and electroplating processes. Clean and uniform surfaces ensure stable coating quality, with custom bulk processing available.
Know More
Professional metal pickling and rust removal treatment removes rust layers, scale and welding stains for thorough cleaning even in hard‑to‑reach areas of workpieces. It ensures durable adhesion of subsequent coatings, suitable for pre‑treatment of various hardware and steel structural parts.
Know More
Metal grinding and brushing are fine surface‑treatment processes. Mechanical polishing creates a uniform and delicate brushed finish on workpieces while removing burrs, scratches and oxidation defects. It enhances the metallic texture for decorative purposes, improves surface flatness and boosts adhesion for subsequent coatings. Suitable for processing decorative hardware and structural parts made of stainless steel, aluminum alloy and other materials.
Know More
Metal polishing is a precision surface‑treatment process. It removes burrs, scratches, oxide layers and machining marks on workpieces through buffing and grinding to achieve a bright, smooth metallic finish. It effectively improves surface smoothness and texture, reduces dirt adhesion and enhances corrosion resistance, while strengthening the adhesion of subsequent coatings such as electroplating and spraying. Widely applicable to various hardware fittings, decorative components and mechanical parts made of stainless steel, aluminum and copper.
Know More
Electrophoretic coating is an eco‑friendly anti‑corrosion surface treatment process. Under the effect of an electric field, paint film is evenly deposited on metal workpieces to form a dense protective coating with excellent adhesion. The coating features consistent thickness and full coverage on edges and inner cavities, delivering outstanding salt‑spray resistance, corrosion resistance and wear resistance with stable and attractive colours. It serves as a high‑quality anti‑rust and decorative coating solution for carbon steel, aluminium alloy, galvanized hardware, structural components and auto parts.
Know More
Powder coating is an eco‑friendly dry finishing process. Electrostatically charged powder paint is melted and cured on metal surfaces to form a thick, dense protective and decorative coating. The coating boasts strong adhesion, excellent impact, corrosion and ageing resistance, with a wide selection of colours and finishes such as matte and textured grain. Free from solvent emissions, it is environmentally sustainable. It is suitable for carbon steel, aluminium alloy and galvanized hardware fittings, sheet‑metal structures, enclosures and outdoor components, delivering long‑lasting rust and weather protection.
Know More
Metal oxidation surface treatment forms a dense native oxide film on metal surfaces via chemical or electrochemical methods, with strong bonding to the substrate. Blackening/bluing for steel parts provides rust protection. Anodizing for aluminum/titanium alloys improves wear and corrosion resistance and allows decorative dyeing. The process includes degreasing, activation, oxidation and sealing, widely used in precision hardware, electronics and auto parts.
Know More
Metal electroplating deposits a metallic coating on workpieces. It firmly bonds to substrates to boost rust resistance, wear resistance and conductivity, with decorative finishes. Common types: zinc, nickel, chrome and copper plating. Widely applied to precision hardware, machinery and electronic components. Process: degreasing, pickling activation, electroplating and post-treatment.
