Nano(CVD) Diamond Coating Dies

Sanbid factory can provide nano die from φ0.50mm to φ40mm for Wire and Tube Drawing. The service life of nano-die for drawing aluminum wire is more than 30 times longer than that of cemented carbide die;

Compared with other molds, nano die can achieve lower friction and better utilization of copper and aluminum when drawing copper wire. Better surface finish.

CVD/Nano diamond coated die has a wider diameter range than PCD, a smoother mirror polished surface treatment, and an ultra-high cost performance

Since CVD-coated diamond dies overcome the anisotropy of natural diamond dies and have excellent strength and hardness, CVD-coated diamond wire-drawing dies are ideal for drawing small diameter wires.

Nano/CVD (Chemical Vapor Deposition) coating die is coated with diamond film on the cemented carbide die. The material is pure diamond polycrystalline, which has the smoothness, temperature resistance and wear resistance of polycrystalline diamond. It is the first choice for replacing rare natural diamonds to make drawing dies.
