Why Choose Relink Nano-Diamond Coating Technology?
Relink Nano Drawing Diesrepresent the pinnacle of wire processing technology. Utilizing advanced CVD (Chemical Vapor Deposition), we grow a dense layer of nanocrystalline polycrystalline diamond (PCD) onto a high-strength tungsten carbide substrate. This hybrid structure perfectly integrates the impact toughness of carbide with the extreme hardness of diamond.
1. Extreme Hardness & Ultra-Long Service Life
-
10,000 Vickers Hardness: The nano-coating hardness is nearly identical to natural diamond, far exceeding traditional tungsten carbide (approx. 1,800 HV).
-
10–20x Longer Lifespan: When processing low/medium carbon steel, stainless steel, and non-ferrous alloys, the wear resistance is vastly improved, drastically reducing die replacement frequency.
-
Superior Bore Stability: The ultra-slow wear rate ensures that wire diameters remain within micron-level tolerances across thousands of kilometers of drawing, preventing material waste caused by “over-tolerance” (oversized) wire.
2. Mirror-Like Surface Finish
-
Nanocrystalline Structure: Unlike standard diamond particles, the nano-scale grain structure provides an exceptionally smooth die bore surface.
-
Elimination of Galling & Metal Fines: High chemical inertness prevents metal adhesion (especially with Aluminum and Copper), completely solving the issues of surface scratches and burrs on the finished wire.
-
Enhanced Product Value: Ideal for high-precision applications like magnet wires and PV ribbon, delivering a flawless metallic luster.
3. Low Friction Coefficient & High-Speed Performance
-
Self-Lubricating Properties: The friction coefficient of the nano-diamond surface is extremely low (μ≈0.05), significantly reducing drawing resistance.
-
Support for High-Speed Drawing: Reduced friction leads to less heat accumulation. Even at high speeds exceeding 20m/s, the integrity of the lubricant is preserved, preventing wire annealing and extending the life of your drawing fluids.
-
Energy Efficiency: Lower drawing force requirements mean reduced motor load, potentially saving your facility 5%–10% in energy consumption.
4. 80% Reduction in Production Downtime
-
Continuous Productivity: Traditional TC dies require frequent inspections and changes. With Relink Nano Dies, your equipment can achieve significantly longer continuous operation cycles.
-
Low Maintenance Requirements: The die bore is resistant to buildup and scaling, extending maintenance intervals and allowing your production line to achieve “high output, low maintenance.”
