Ajex & Turner has introduced VNT PCD dies for stranding, compacting and bunching for copper and aluminium and for low carbon welding wire drawing to save power con- sumption and metal, avoid heat generation on the die and conductor and to maintain the bright surface. The innovative VNT PCD dies have been successful for a number of years in controlling the CR value, compacting ratio, and ensuring a two to three per cent metal saving. There is also no dust creation. The company has developed a range of the dies from 0.7 to 100mm for electrodes, CO 2 welding and stainless steel wires, etc, which it claims can improve production, reduce the manufacturing cost and save power. The dies are made with multi-layer coatings of nanocrystalline diamond through vapour deposition on the hardest base metal, which provides a smooth surface with low friction. Nanocrystalline diamond has been used extensively to improve the properties of surfaces for manu- facturing processes, due to favourable material properties such as hardness, improved wear resistance, excellent thermal conductivity, chemical inert- ness and low coefficient of friction. Some of the benefits include: • The size and polish remains the same throughout the life of the die • No need for re-polishing and resizing • Cost effective • The surface finish of the wire is very bright (almost like a mirror polish) which improves conductor quality • More metal saving up to two to three per cent • No dust accumulation in the die and resist-free from breakage and scratches on the conductor and wire. No heat generation on the die and conductor Lower power consum- ption on continuous use of VNT PCD dies
