Surface Finishing
Multiple surface treatment options are available to meet diverse industrial standards, supporting customized finishing according to your technical specifications.
Common Types of Surface Treatment
| Finish Type | Applicable Materials | Description |
| As machined | Metal, plastic | Raw CNC finish with sharp edges safely deburred. Typical roughness average: Ra > 3.2 µm. |
| Electroplating | Metal | Electro-deposited metallic coating that substantially boosts surface hardness, corrosion protection, and visual finish. |
| Anodizing | Metal | Electrochemical conversion that builds a durable oxide layer for superior wear resistance and sleek color options. |
| Powder Coating | Metal | Thermally cured polymer coating delivering heavy-duty impact resistance and long-lasting weatherproofing. |
| Painting | Metal, plastic, ceramic, composites | Precision liquid spray application providing uniform aesthetic finishes, available in custom matte, satin, or high-gloss shades. |
| Brushing | Metal | Directional satin graining that diffuses surface reflections and conceals minor handling marks. |
| Sand Blasting | Metal, plastic, ceramic | High-velocity abrasive blasting to clean contamination, remove tool marks, and create a uniform matte texture. |
| Black Oxide | Metal | Chemical conversion process yielding a dark matte finish for improved rust suppression and non-reflective aesthetics. |
| Teflon Coating | Metal, plastic, ceramic | High-performance fluoropolymer layer (PTFE) engineered for extreme heat resistance and ultra-low surface friction. |
| Electrophoretic | Metal | E-coating process ensuring complete pinhole-free coverage, maximum edge coverage, and strong primer adhesion. |
| Passivation | Metal | Chemical treatment for stainless steels that strips free iron and forms a passive, rust-resistant surface film. |
| Alodine | Metal | Chemical chromate conversion coating designed for corrosion prevention and ideal paint bonding on aluminum. |
| Chromate | Metal | Chemical conversion process that produces a protective passivation layer against oxidation and corrosion. |
| PVD | Metal, ceramic, plastic | Physical Vapor Deposition technique applying ultra-thin, highly wear-resistant ceramic coatings with metallic lusters. |
| CVD | Metal, ceramic | High-temperature chemical vapor process creating hard, dense protective films for extreme environments. |
| Electroless Plating | Metal, plastic | Autocatalytic chemical plating delivering an exceptionally uniform metal layer for enhanced wear resistance and conductivity. |
| Electropolishing | Metal | Electrochemical micro-smoothing process that eliminates surface peaks for a mirror-like, ultra-clean finish. |
| Polishing | Metal, plastic, ceramic | Precision mechanical grinding and buffing to achieve high surface smoothness and a reflective gloss. |
| Silk Screen | Metal, plastic | Mesh-based ink transfer method for printing durable, high-contrast labels, text, and brand logos. |
| Laser Engraving | Metal, plastic | High-precision laser etching for permanent, highly detailed part numbers, barcodes, and custom designs. |
