Technology does dust free and saves metal

due to favourable material properties such as hardness, improved wear resistance, excellent thermal conductivity, chemical inertness and low coefficient of friction. The manufacturer states that by using VNT dies, the user will get good performance of wire surface and better production than TC and PCD. It is found to be cost effective, leaving a bright surface on the wire, and with low energy consumption, metal saving, etc. Ajex & Turner Wire Technologies – India Website : www.ajexturner.com

AJEX & Turner manufactures a variety of wire drawing and compacting dies and tools for the wire and cable industries. The company offers a range of VNT dies from 0.7 to 100mm for electrodes, CO 2 , welding and stainless steel wire, etc. These dies are made with multi-layer coatings of nanocrystalline diamond through vapour deposition on carbide base metal, which provides very smooth surface with low friction. Nanocrystalline diamond coatings have been used extensively to improve the properties of surfaces for manufacturing processes,

Wire green cleaning for plating quality

▲ ▲ Wire cleaning by PWC system

The wire cleaning and polishing in-line with the wire-drawing machine. Cleanliness permits direct wire brass coating, copper coating, galvanising, wire cleaning prior to heat treatment, etc. new technology that enables normal cold plant water to be converted into a cleaning medium, generating high- pressure wetting/contaminants extreme pressure extrusion/hydrodynamic cavit- ations displacement and contaminants flush out, used to clean drawn wire at high speed in a completely green application, providing a glossy wire finish in plating quality. The PWC system effectively removes lubricant residue from the base material and is particularly recommended by Decalub for cleaning applications with wires drawn in severe conditions. For decorative mirror reflective wire applications, the system can be used with a light emulsion diluted at 3-5 per cent concentration. The PWC unit is compact and can be easily installed on the finishing/last block of a drawing machine. Decalub – France Website : www.decalub.com PWC system performs The system incorporates
