CVD Wire Drawing Dies

CVD (Chemical Vapor Deposition) coating drawing die is a recently developed a new technology, its main way is the Carbide Drawing die coating diamond films. CVD diamond coating drawing die due to a good performance and wear resistance, low surface roughness of the wire drawing, but drawing die CVD coating production process is complex, difficult process, high cost; when the coating abrasion After the mold will quickly wear, not only difficult to ensure processing quality, but can not be reused, it can only be scrapped.

Diamond films are pure polycrystalline diamond, both with single crystal diamond finish, temperature resistance, but also has low abrasion resistance and price of polycrystalline diamond, etc., to achieve well in place of rare natural diamond Drawing Die preparation tools the effect of its widespread use will bring new vitality drawing die industry.

When drawing a small diameter wire, CVD diamond coating to overcome the natural diamond die mold anisotropy, but also has excellent strength and hardness, drawing the highest yield, surface quality meet the requirements. Test proved, CVD diamond coating life drawing die mold identical to the natural diamond, high qualified products, surface quality than domestic polycrystalline diamond. Thus, for small diameter wire drawing, CVD diamond coating drawing die is an ideal choice.


1. CVD diamond coating prepared by DC arc plasma spraying method has high diamond purity and fast deposition rate
2. The DC arc plasma jet method uses plasma jet to pass through the inner hole of the mold, and the jet shape and cross-sectional area are easy to control. It is very suitable for large-aperture molds and special-shaped molds that are difficult to make by hot wire method.
3. 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.


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

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


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.
