Nano crystalline diamond dies Ajex & Turner is a technology-driven company, and has been engaged in the manufacturing of a variety of wire drawing and compacting dies and tools for the wire and cable industries since 1962. smooth surface with low friction. VNT Nano dies can be made for sizes from 0.4 to 250mm for drawing, compacting, TW, sectors and Z-shapes. The dies can be used for drawing copper or aluminium for stranding, compacting, bunching, rod break down (RBD) sizes, sectors, TW, Z-shape wire, etc. They can draw aluminium alloy wire, nickel silver wire, brass, copper tubes, and stainless steel or high- and low-carbon steel wire up to 0.6%C, welding wire or any hard/soft wire of any size and hardness. Lower friction results in better copper and aluminium utilisation. The manufacturer claims an improvement of 3-4 per cent in raw material utilisation and better life than PCD and tungsten carbide dies. No die polishing or re-cutting is required for any metal. For aluminium/copper RBD processes, Nano dies allow continuous processing with no metal loss. The casings are made from stainless steel grade 304 to avoid rust. A range of dies from Ajex & Turner The company’s VNT Nano dies are made by Ajex in India with multi-layer coatings of nano crystalline diamond through vapour deposition, which provides a

Using tungsten carbide dies for soft or hard material, there is a chance of dust accumulation in the die, and wire breakage and scratches on the conductor. With polycrystalline diamond dies, diameters can be controlled but variation may eventually occur. Nano is claimed to maintain zero per cent tolerance throughout its working life, with no need for re-polishing or re-grinding. Ajex & Turner dies are fully guaranteed for 24/7 use for compacting up to 20,000 km of conductor. Superglow lubricant can be used to cool the die for maximum use. Ajex & Turner Wire Technologies Pvt Ltd www.ajexturner.com Customised engineering for payoff and take-up systems Kurre Systems has more than 40 years of experience in the cable and wire industry, as well as in the development of specialised and customised machinery. The company has provided a review of the new products it launched in 2023. The company’s newly delivered double payoff automatically and seamlessly winds, so that upstream or downstream processes can continue at a constant speed. Set-up times due to pintle exchange are eliminated, and the system allows independent setting of the clamping forces of the pintle and friction disc, to handle pressure-sensitive spools. In the area of modern control for extrusion lines, with the completely revised Kurre Control & Database System, the company steps towards Industry 4.0. In addition to the outsourcing of computing power with more options for data tracking, the usability and OPC-UA interface take a major role. Increasing demand and the need for a sustainable design for the future have led Kurre Systems to expand its range of flange-driven winders. The new AB-W-1250 XL and AUF-W-1250 XL models were also designed in response to customers’ requests for higher bobbin loads. In a further development of the drum spooler, Kurre now offers a system that outputs a perfectly wound, foil-wrapped and labelled spool onto a pallet, fully automatically, every 90 seconds or 500m.
