Relink PCD Drawing Dies – Feature

Relink PCD (Polycrystalline Diamond) Wire Drawing Dies stand out in high-speed wire and cable production thanks to their advanced synthetic diamond structure and precision engineering. These dies combine diamond’s extreme hardness with the isotropic properties of polycrystalline material, delivering consistent, reliable performance that outperforms traditional options in demanding applications.

Core Feature & Advantages

• Exceptional Wear Resistance PCD offers 50–200 times longer service life compared to tungsten carbide dies in non-ferrous applications (copper, aluminum, alloys). This dramatically reduces downtime for die changes and lowers overall production costs.

• Uniform & Predictable Wear Pattern Randomly oriented diamond particles in the PCD blank create isotropic hardness — wear occurs evenly in all directions, resulting in a perfectly round wear profile. This keeps the drawn wire perfectly round and consistent throughout the die’s entire lifespan.

• Superior Wire Quality & Surface Finish High polish and low-friction entry/exit zones produce mirror-like wire surfaces with tight diameter tolerances and minimal defects. Ideal for high-quality requirements in electronics, aerospace, automotive, and power cables.

• Outstanding Thermal Conductivity 2–3 times better heat dissipation than natural diamond, effectively managing heat buildup during high-speed drawing. This preserves wire metallurgical properties and supports faster production speeds without compromising quality.

• High Hardness with Enhanced Toughness Diamond-level hardness (far superior to carbide) combined with improved impact resistance and crack prevention, making PCD suitable for both wet and dry processes, as well as abrasive or high-tension wires.

• Wide Size & Shape Flexibility Hole diameters from ultra-fine 0.04 mm to large 35 mm (custom larger sizes available). Standard round holes; special shapes like square, hexagon, octagon, rectangle, and more on request.

• Grain Size Options for Customized Performance Available in various grain sizes (e.g., 3–5 µm for ultra-smooth finishes, 10–25 µm for balanced wear, up to coarser for maximum durability), allowing optimization for specific wire materials, speeds, and finish needs.

• Blank Configurations Self-supported or tungsten carbide-supported blanks for added strength in larger sizes or high-load applications. Cobalt-based or metal-filled options enhance machinability and thermal properties.

• Versatile Applications Excellent for ferrous (select low/medium carbon steel, stainless) and non-ferrous wires, including copper/aluminum conductors, welding wires, CO₂ shielding wires, medical wires, superconducting wires, and high-corrosion-resistant alloys.

• A high-resolution macro photo of a used PCD die cross-section showing the perfectly uniform, round wear pattern (contrast with irregular carbide wear).

• Side-by-side wire samples: one drawn with Relink PCD (mirror-smooth surface) vs. standard die (visible imperfections).

• Infographic icons or grid illustrating the key features (e.g., icons for wear resistance, thermal conductivity, roundness, with arrows and short descriptions).

• Grain size comparison chart with magnified views of different PCD structures and corresponding wire finishes.

These features make Relink PCD dies the go-to choice for manufacturers seeking maximum uptime, superior quality, and long-term cost efficiency in high-volume wire drawing operations. Relink ensures every die undergoes rigorous quality control from blank to final polish.

Thanks to the extreme durability of diamond and carbide components, Relink tools offer significantly longer service life compared to standard steel tooling. This reduces downtime for tool changes and reconditioning, lowering overall production costs.

Our tools are optimized for modern high-line-speed processes, maintaining stability and precision even at elevated temperatures and pressures common in LV/MV/HV cable manufacturing.
