VNT dies offer multiple advantages

❍ VNT dies from Ajex & Turner

Ajex & Turner Wire Dies has introduced a line of innovative VNT dies (Vitrified Nanocrystalline Technology) that can replace PCD and carbide dies for multiple applications in drawing and compacting. VNT dies offer more wear resistance, and have an extremely smooth surface with immensely low friction. The dies can draw stainless steel wire or carbon steel wire up to 0.6%C, aluminium or Al alloy wire, and nickel silver wire as well as copper/brass tubes and for compacting/stranding copper and aluminium. The dies, which are offered for a range of 0.8mm to 70mm for stainless or carbon steel wire, provide a two to three per cent improvement in raw material use for metal savings. The dies can provide a perfect surface finish, holding a zero tolerance for up to 500 metric tons (stainless steel and carbon steel wire up to 0.6%C) at a price that is 2-10 times lower than PCD dies (depending on bore diameter). These dies produce a smooth wire due to the unique diamond technology used. “The diamond coating is very thin, thus it will not peel off as in the case of a thick coating, thus increasing the life of the die and providing better performance, which is evident by the overwhelming responses by our overseas customers who have used these dies for copper, aluminium, stainless steel, aluminium alloy, etc,” said a statement. “For high and low carbon, in association with TKT, Italy, we have developed pressure dies for long life. These dies are used for dry and wet drawing respectively. With its revolutionary concept of disassembled die, it improves lubrication, gives 30 per cent more nib or pallet life and produces higher quality wire. Our pressure dies contribute significantly to increase drawing speeds and improve productivity to the wire plant.” By using the pressure die, the re-cutting or refurbishment is eliminated and the wire drawing speed also increases up to 50 metres per second. Ajex has developed different grades of Masterlube lubricants, which have high viscosity and low consumption. Ajex & Turner Wire Dies Inc – India Website : www.ajexturner.com
