High thermal conductivity PCD wire drawing die

1.Excellent corrosive wear resistance. 2.Available in a large range of sizes. 3.High drawing efficiency. 4Good surface finis.

Polycrystalline drawing die is composed of diamond powder and produced by adwanced high temperature and ultra-high pressure condition in the presence of metal catalyst ( cobalt ). Under the strict control condition of the process, the diamond-to-diamond combination key forms between diamond microcrystalline particles. So it has high hardness and high thermal conductivity similar to natural diamond. At the same time, because of the irregular arrangement of diamond powder,the polycrystalline diamond is isotropic, so orientation is out of consideration during processing and it has better toughness and wear resistance.

Standard hole shape designs for variety kinds of wires are as follows:   

Aperture(mm)	Tolerance(μm)	Circular degree(μm)	Shell size ( standard )
			Outside diameter(mm)	Thickness(mm)
Φ0.050~0.099	1	0.5	25	8
Φ0.100~0.499	2	1	25	8
Φ0.500~0.999	4	2	25	10
Φ1.000~1.999	6	3	25	12
Φ2.000~10.000	8	4	30	15

Our company can also supply wire drawing dies in different shell size and aperture tolerances according to the requirements of customers.
