CVD Coated diamond Die

The diamond coated die has low friction coefficient when drawing copper tubes, which ensures good surface finish of copper tubes and can save 1-2% of copper raw materials

Nano-coating dies is to form CVD diamond coating on the surface of tungsten carbide mold,Under the same working conditions, the service life of the CVD diamond coated wire drawing die is more than 30 times that of the cemented carbide wire drawing die,
