Matte Black Anodized Precision Machined Parts With ±0.05mm Tolerance For Automated Assembly Lines
Matte black anodizing is crucial for precision machined parts. It forms a dense oxide film, significantly enhancing the wear resistance and corrosion resistance of the parts, which can resist industrial contaminants and extend the service life. Its non-reflective surface can avoid light interference, making it an ideal choice for medical devices and automated production lines. The uniform surface texture and stable friction coefficient help improve the efficiency of automated assembly and reduce errors, while the simple matte black appearance combines functionality and aesthetics.
Diversified Surface Treatment Solutions
At JINGXIN, we offer more than just matte black anodizing:
- Hard anodizing can enhance surface hardness, suitable for high-wear parts;
- Electroplating (chrome, nickel, zinc, etc.) can improve corrosion resistance and conductivity, widely used in the electronics and automotive fields;
- Passivation treatment can enhance the rust resistance of stainless steel;
- Sandblasting can adjust surface roughness to optimize friction performance or adhesion.
We will customize solutions according to part requirements to ensure their performance and reliability.
