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.

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.
Choosing the right PCD die for wire drawing is essential for achieving optimal performance and product quality. Here are some factors to consider when selecting the right PCD die for your wire drawing application:
- Material to be drawn: The material being drawn will affect the selection of the PCD die. Different materials have different hardness and abrasiveness, which can affect the performance of the die. The PCD die must be selected based on the properties of the material being drawn.
- Wire diameter: The wire diameter also plays a crucial role in selecting the PCD die. The die should be designed to handle the specific wire diameter range required for the application.
- Surface finish requirements: The surface finish of the wire is another important factor to consider. The PCD die should be selected based on the desired surface finish of the finished wire.
- Production volume: The production volume is also an important consideration. If the production volume is high, a PCD die with a longer lifespan may be required.
- Cost: The cost of the PCD die should also be considered. PCD dies can be more expensive than other types of dies, so it’s important to choose a die that provides a good balance of performance and cost.
- Die design: The design of the PCD die is also important. The die should be designed to minimize wire deformation and ensure consistent wire quality.
- Supplier reputation: It’s important to choose a reputable supplier with experience in producing PCD dies for wire drawing applications. The supplier should be able to provide guidance on selecting the right PCD die for the application and offer assistance with die maintenance and repair.
By considering these factors, you can select the right PCD die for your wire drawing application and achieve optimal performance and product quality.
Polycrystalline diamond (PCD) dies require regular maintenance to ensure their longevity and optimal performance. Some of the maintenance tasks that are typically required for PCD dies include:
- Cleaning: The dies should be cleaned regularly to remove any dirt, debris, or residue that may accumulate on the surface. This can be done using a soft-bristled brush and a cleaning solution that is specifically designed for diamond materials.
- Inspection: Regular inspection of the dies is necessary to identify any signs of wear or damage that may affect their performance. The dies should be inspected for cracks, chips, or other signs of wear, and any issues should be addressed promptly.
- Reconditioning: PCD dies may need to be reconditioned periodically to restore their surface finish and ensure proper performance. This process involves removing a thin layer of material from the surface of the die to expose fresh diamond grains.
- Lubrication: Proper lubrication is important to reduce wear and friction on the dies during use. The type of lubricant used will depend on the specific application and should be chosen carefully to avoid any contamination or damage to the diamond surface.
- Storage: Proper storage is essential to protect the PCD dies from damage when they are not in use. The dies should be stored in a clean, dry environment and protected from exposure to extreme temperatures or humidity.
Overall, regular maintenance is critical to ensure the optimal performance and longevity of PCD dies.
