Nano diamond coated dies with ultra-low friction

Weilly Diamond develops nano diamond coated dies that combine tungsten carbide strength with advanced nano-diamond coating technology. The nano-diamond layer, applied to the die bore, provides superior hardness, toughness, and thermal conductivity while drastically reducing friction—up to ten times lower than conventional diamond dies and a hundred times lower than standard tungsten carbide dies.

This advanced coating delivers exceptional wear resistance, extended die life, and enhanced surface quality for drawn wires. It also minimizes burr formation and electrical breakdown, improving conductivity and reducing energy loss during production.

Engineered for medium to large wire sizes and high-speed drawing operations, these dies are ideal for power cable, automotive, telecom, and electrical component manufacturing. With optimized die geometry and strict in-house quality control, Weilly Diamond ensures consistent precision, energy efficiency, and reliable performance across high-volume production lines.
