CVD diamond coating wire drawing die, using carbide substrate as raw material and chemical vapor deposition (CVD), was used for micro level and nano level diamond composite coating on the inner surface of the dies, and then the coating was polished and polished to obtain a new die. The inner hole surface of the die is close to the nature of natural diamond, and has the characteristics of high finish and good wear resistance.

Under normal use, the drawing tonnage reaches over 30 times that of the carbide drawing die;

Advantages of CVD diamond coating wire drawing die

• Ultra fine nano polished surface to improve wire quality;

• No special lubrication is required, and clean lubricating medium can achieve ultra-long service life of molds
