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.
Features:
- 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.
Design Condition of Dies:
- Size of initial wire
- Reduction angle control
- Performance of drawing machine
- Property of drawing lubricant
- PCD insert size
- PCD grain size
- Hole geometry
- Casing size
UKO also produces various poly-crystalline special-shaped wire drawing dies such as square, rectangular, triangle, hexagon, semicircle, oval, sector, Z shape, and tile shapes.
The minimum eyelet for square drawing dies is 0.18×0.18 mm, the minimum eyelet for rectangular dies is 0.08×0.20 mm, the minimum eyelet for semicircular dies is 0.20×0.40mm, and the minimum eyelet for triangular is 0.25×0.25mm, and other specifications and shapes can also be customized according to customer requirements.
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.
Benefit
- Durability: PCD wire drawing dies have excellent wear resistance, resulting in longer service life and reduced downtime.
- Precision: PCD dies can maintain their shape and dimensions even under high pressure and extreme temperatures, ensuring consistent wire size and quality.
- Cost-effectiveness: Although PCD wire drawing dies have a higher upfront cost, their longer lifespan and improved wire quality result in lower overall production costs.
