PCD Wire Drawing Dies (polycrystalline wire drawing dies) with Cobalt base is a good product with close performance to imported polycrystal, with long lifetime, high finish, high mold concentricity, mold parameter control and other advantages.
Feature:
1) Cobalt-based PCD wire drawing die blank contains metal bond, has good processing properties
2)Can use electric sparks, lasers, ultrasonic and other processes for processing
3)The presence of metal cobalt makes diamond easy to graphite at high temperatures
4)PCD die blank is suitable for processing and use at less than 650 degrees Celsius conditions
Advantages:
1)better surface finish
2)minimum friction
3)higher wear resistance
4)high effeciency
5)a wide range of grain and nib sizes
6)perfect characteristics of crack proof
7)smoothness, durability predicted
8)Good polishing of wire or tube surface
9)Fast delivery time at about 7-10 days after receive your payments
PCD Wire Drawing Dies-Co Base Application:
Recommended for requirements of middle and high quality of wires, such as: cutting wire, structural wire, metal wire, copper wire, aluminum wire, welding wire, stainless steel wire, spring wire, copper-plated wire and other various non-ferrous or non-ferrous metal wire.

PCD dies- Co base have two different die blank: Self-Supported Die Blanks
& Tungsten Carbide Supported Die Blanks.
Dies with tungsten carbide supported eie blanks can withstand greater pull, more used in the manufacture of large aperture mold embryo, pulling a thicker diameter of wire - 3mm or more wire is recommended with carbide ring.
