• PCD Wire Drawing Dies

We offer PCD wire drawing dies that could change the polishing technology according to different drawing machines, such changes could make the drawing dies more suitable on different wire drawing machines, and the use span life is longer and save the cost of production, improving the production efficiency.


  • Supper fine & even particle diamond.
  • High drawing life.
  • Better perforation on hardwire drawing.
  • Low tolerance and high finished wire surface.
Poly Crystalline Diamond (PCD) wire drawing dies that can be used for ferrous and non-ferrous wire drawing applications. Sizes are available for drawing applications ranging from ultra-fine wire to large drawn rod. This size range include 0.040 to 35 mm (.00157 – 1.378″). PCD dies offer a high resistance to wear and an excellent wire surface finish.

Copper wire, Aluminum wire, Tungsten wire, Molybdenum wire, Stainless steel wire, Coated steel wire, Special alloy and high-performance alloy wire, Precious metal wire, Various other ferrous and non-ferrous metal wire types.

When you need to customize diamond wire drawing dies, please consider the following factors:

  • PCD insert size
  • PCD grain size
  • Hole geometry
  • Casing size

PCD’s tensile strength is only 70% of that of tungsten carbide but its hardness is 2.5 times that of tungsten carbide. These two characteristics make PCD wire drawing dies have the following advantages:

  • High drawing efficiency.
  • Good abrasive resistance.
  • Good impact resistance.
  • Superior wire surface.
  • Reduction of labor intensity.

Difference between PCD and tungsten carbide dies

  • PCD dies lifetime is 30-50 times as that of tungsten carbide dies. In this case, it does not need to stop machines to change dies. Moreover, PCD dies’ diameter changes a little in-unit time so the wire diameter also changes little. This is very good for reeling wire.
  • PCD wire dies’ long lifetime and small hole change greatly reduce workers’ labor intensity.


  • Flat thread rolling dies with precision classes 1, 2, or 3 we can be manufactured and processed according to specific precision requirements.
  • Through a series of heat treatments, the hardness of the dies can reach HRC 63, resulting in stable performance and high efficiency.
  • Besides, materials such as Cr12MoV, DC53, and high speed tool steel can be offered, and thread forms such as ANSI, BS, DIN, and JIS are also available.
