The nano-diamond coating drawing die is made of cemented carbide (WC-Co) as the substrate, and the surface of the inner hole is coated with a micro-nano-scale diamond composite coating by chemical vapour deposition (CVD), which is ground and polished.


The Advantages of Nano-coated drawing die.

  1. Targeted pre-treatment process: make the coating and substrate closely combined.
  2. The bottom micron diamond coating has excellent wear resistance.
  3. The surface nano diamond coating provides an excellent surface finish and low friction coefficient.
  4. Computer simulation and optimization of hole design: high dimensional accuracy, uniform stress on the wire rod, saving raw materials.
  5. There is no change in the diameter of the die from use to scrap, reducing the times of downtime inspection and drawing die change and improving production efficiency.
  6. Wider diameter range, service life is 5 to 10 times that of tungsten carbide.
