PCD Wire drawing dies are made of micron-sized diamond particles and bonding agent sintered under high temperature and high pressure. It has the advantages of high hardness, good wear resistance, and strong impact resistance.
PCD Wire drawing dies are widely used, such as high precision wire materials used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires are all drawn with diamond wire drawing die. The manufactured diamond wire drawing die has strong abrasion resistance and high service life because it uses natural diamond as raw material. The production process of wire drawing die set includes several process steps such as stamping, drafting and turning.
CVD diamond, also known as chemical vapor deposition diamond, is a pure diamond deposited on the surface of a solid substrate with carbon-containing gas under high temperature and low pressure conditions. CVD diamond has high hardness, good wear resistance, low friction coefficient and high surface finish. It can be made into wire drawing dies with 0.02-1.0mm aperture for drawing stainless steel wire, tungsten wire, molybdenum wire, copper wire, aluminum wire, etc. Since CVD diamond does not contain any bonding agent, compared with PCD, CVD diamond wire drawing dies show higher wear resistance, corrosion resistance, thermal conductivity and thermal stability. The disadvantage of this product is that its toughness is not as good as PCD, its impact resistance is weak, and it is easy to crack. The technical conditions in the preparation of the wire drawing die are also stricter than PCD.
1. Long life, greatly reducing the frequency of die change;
2. Special pre-treatment technology to create super Ø adhesion strength, extended die life;
3.Ultra-fine nano-level polished surface improves wire quality;
4.Improve drawing speed, ultra high-speed drawing, improve production efficiency;
5.No special cooling, water cooling can ensure long life;
6.No special lubricating, clean the lubricating medium to achieve both long dies service.
