Product Introduction

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 phenomenonin even in the 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 anaisotropic, 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 receive your payments

Application

PCD Wire Drawing Dies-Si baseapplication:

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.
