Polycrystalline diamond(PCD) sintered under high temperature and high press together with binder alloy is used. Diamond Drawing dies of high and consistent quality covering small to large diameters exhibit outstanding performance in larger size areas than single crystal diamond drawing dies. There are some factors to consider when specifying a PCD die, PCD insert size, PCD grain size, casing size and hole geometry.

1,Raw material composition
The raw material of Pcd drawing dies from GE ,USA.The useful life is much longer than ordinary material.As we all know,people spend a lot of times on change the broken drawing dies,so the better the drawing die ,the better productive efficiency.        
 
2,Heat conduction performance of high corrosion resistance
Cemented carbide drawing die, on the wire drawing process, the heat generated by cemented carbide die conduction, lower friction coefficient, in the wet drawing lubrication, the cooling lubricant with good corrosion resistance, wet lubrication drawing in acid solution, is more effective!

Application:

Soft wires: Copper wire, Aluminum wire, brass wire, gold wire, etc.
Hard wires: Stainless steel wire, brass plated steel wire, cooper plated wires, tungsten wire, molybdenum wire, etc.
