PCD Wire Drawing Dies

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.

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.

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.

We can supply full line services in PCD die blanks, PCD semi-finished dies and finished dies. We can supply overall solutions to customers. You will enjoy your buying convenience.


1. Ultra-fine nano-level polished surface improves wire quality;
2. Special pre-treatment technology to create super Ø adhesion strength, extended die life;
3. Long life, greatly reducing the frequency of die change;
4. Improve drawing speed, ultra high-speed drawing, improve production efficiency;
5. No special lubricating, clean the lubricating medium to achieve both long dies service.
6. No special cooling, water cooling can ensure long life;

Our company set up an advanced, world-class testing and inspect center for PCD dies, to check the quality of PCD die blanks. With the development of test center, we accumulate a lot of experience on PCD die blanks, which will be more helpful in the further R&D development. Meanwhile, we can supply technical supports to customer when they met issues.


Copper wire, Aluminum wire, Stainless steel wire, Coated stainless steel wire, Tungsten wire, Molybdenum wire, Welding wire, Large diameter tubes etc.

Uking PCD dies are widely accepted by different wire drawing Wet and Dry Stainless steel, Medical, Low and High Carbon Steel, Welding wire, Copper & Aluminum conductors, Magnet, EDM Tungsten, Molybdenum, Coated and alloy wires etc. Right selection of PCD blank and profile ensures perfect compacting of conductors, good surface and long life.
