Core Surface Treatment Technologies

I. Mainstream Core Processes

1. Electroplating

Through a precise electrolytic process, we deposit a uniform nickel, chromium, or copper plating layer on the surface of metal substrates, effectively improving the corrosion resistance, wear resistance, and surface gloss of plated coated parts. This process is suitable for various substrates such as stainless steel and aluminum alloys. After process optimization, the coating thickness is uniform and consistent, with strong adhesion, meeting the needs of high-precision applications. It is widely used in precision electronic components, hardware accessories, and other products.

2. Hot-Dip Galvanizing

Our hot-dip galvanizing process immerses metal parts in molten zinc at 445℃-450℃, forming a dense zinc-iron alloy layer and a pure zinc surface layer on the substrate. This metallurgical bonding method ensures strong adhesion between the coating and the substrate, providing long-term effective corrosion protection for outdoor hardware and structural steel, suitable for plated coated parts exposed to humid, outdoor environments for extended periods.

3. Anodizing & Electrolytic Coloring

This process is primarily applied to plated coated parts made of aluminum and aluminum alloys. Through an electrochemical reaction, a hard oxide film is formed on the substrate surface, significantly improving the product's corrosion resistance, wear resistance, and insulation properties. The subsequent electrolytic coloring process achieves a stable, fade-resistant appearance with a variety of colors, suitable for automotive trim parts, electronic trim parts, and other products requiring both aesthetics and performance. Depending on the needs, it can be divided into Type II (ordinary anodizing) and Type III (hard anodizing), suitable for decorative and demanding wear-resistant applications, respectively.

II. Chemical and Mechanical Auxiliary Treatments

1. Blackening Treatment

Through a controlled chemical reaction, a black oxide film is formed on the steel surface, providing basic rust protection for plated coated parts while also presenting a simple and sophisticated matte finish. Suitable for applications requiring a low-key appearance, such as mechanical parts and hardware tools.

2. Spraying

This includes both spray painting and powder coating. Spray painting offers a wide range of colors and gloss levels to meet diverse decorative needs; powder coating significantly improves the wear resistance of plated coated parts, providing strong adhesion and resistance to peeling, making it suitable for products with high protective requirements, such as outdoor equipment housings and appliance components. We use professional spraying equipment to ensure a uniform coating free of runs, bubbles, and other defects.

3. Polishing & Brushing

Polishing creates a high-gloss, smooth finish on stainless steel and copper plated coated parts, reducing surface imperfections and facilitating cleaning. Brushing creates fine, thread-like textures on the substrate surface, effectively concealing minor scratches and presenting a unique textured look. This is suitable for decorative plated coated parts made of aluminum alloy and stainless steel, such as furniture hardware and electronic housings.

4. Sandblasting & Electrophoresis

Sandblasting removes impurities and oxide layers from the substrate surface, improving surface roughness and providing a good foundation for subsequent coating adhesion, ensuring that the coating on plated coated parts is not easily peeled off. Electrophoresis, on the other hand, forms a uniform, corrosion-resistant coating on stainless steel and aluminum alloy substrates. The coating is dense and provides excellent protection, making it suitable for precision parts with high corrosion resistance requirements.
