PCD Wire Drawing Dies (polycrystalline wire drawing dies) is composed of diamond powder under the action of Metal Catalyst (silicon), which is sintered by high pressure and high-temperature process.It can ensure the roundness of the wire and has a high surface finish, drawing life is long, it is difficult to appear mold wear and flat line phenomenon in even in a long time drawing process.
Feature:
1.Under strict process control conditions, diamond microcrystalline particles form a diamond fitness combination, so that it has similar high hardness and high thermal conductivity as natural diamond
2.Because of the irregular arrangement of diamond micro-powder, so that polycrystalline diamond performance is anisotropic, processing need not consider its orientation, and has better toughness and wear resistance.
Advantages:
1.good durability
2.high efficiency
3.a wide range of grain and nib sizes
4.perfect characteristics of crack-proof
5.smoothness, durability predicted
6.Good polishing of wire or tube surface
7.Fast delivery time at about 7-10 days after receiving your payments
PCD Wire Drawing Dies-Si base application:
It is widely used to drawing all kinds of wire such as electronic devices, radar, television, instrumentation, and aerospace, such as the use of high-precision wire, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire cable wire and a variety of alloy wire.
