The Nano-Crystalline Advantage
Ultra-Hard Nano-Diamond Layer (CVD Technology)
-
Technical Detail: Each die features a 30μm – 50μm thick layer of nano-crystalline diamond (CVD) chemically bonded to a robust Tungsten Carbide substrate.
-
Benefit: Achieves a hardness of 10,000 Hv (matching natural diamond) while maintaining the fracture toughness of cemented carbide.

Economic Efficiency
1% – 3% Raw Material Savings
- Technical Detail: Traditional TC dies wear out quickly, leading to “oversizing” (wire diameter increases, consuming more metal). Our Nano Dies feature zero-wear precision for thousands of kilometers.Benefit: By maintaining a constant diameter at the lower tolerance limit, you save significant costs on copper and aluminum—the metal saved often pays for the die itself.
Superior Surface Quality
Mirror-Grade Polish & Low Friction
-
Technical Detail: The friction coefficient of Nano-diamond is only 0.05 – 0.1 (compared to 0.25 for TC).
-
Benefit: Minimizes heat generation during high-speed drawing, prevents surface scratches, and ensures a mirror-like finish for high-end electronic and automotive wires.
Optimized Geometry: Zero-Wear Precision for High-Volume Production
Relink Nano Dies feature a high-performance diamond profile designed to reduce material drag and stabilize compacting ratios. Because the CVD surface is essentially wear-resistant, the internal geometry remains unchanged throughout the die’s life.
This long-term precision prevents “oversized” wire waste and reduces the cost of quality rejections, ensuring every kilometer of wire meets your exact specifications.
Material Versatility & Specialized Options
Compatible with copper, aluminum, stainless steel, low/high-carbon steel, and various non-ferrous alloys. Available in shaped profiles (square, rectangular, sector, trapezoid) for stranding, bunching, and compacting; split dies for fast changeovers; and fully custom calibrations to match your exact process needs.
