Our nano-coated wire drawing dies are manufactured with tungsten carbide substrate and advanced nano-coating treatment on the inner bore. The ultra-thin dense coating will not alter the original precise hole dimension. It greatly reduces friction between wire and die wall, effectively preventing metal adhesion and material buildup, delivering much smoother wire surface.Benefiting from superior wear resistance, the die service life is 2–6 times longer than conventional uncoated carbide dies. The bore size remains stable during long mass production, lowering wire breakage and defect rates. It also features good corrosion resistance against drawing lubricants. Less downtime for die replacement helps cut your overall production cost. It is the premium precision die choice for high-speed drawing and extrusion of copper, aluminum, alloy and plastic wires.
