thicknesses and prevents wire breakage to a great extent. The smooth surface of the drawing tools also subjects the surface of coated wires to less stress than comparable tools with partially ground surfaces: the wire is manufactured to a higher quality. For applications with especially abrasive materials such as tinned and galvanised wires or precious metals (gold, silver, platinum), the surface of the tools is – in addition to the fine polish – hardened by a special process developed by CeramTec. Drawing tools are pre-ground before assembly and then finely ground, polished and balanced in their assembled form. In this way, they maintain the best possible concentricity even at high rotational speeds. With the capstans and cones manufactured by CeramTec, users can work vibration free. Cersa-MCI designs and produces measurement solutions for fine wires, cables and optical fibre. It is committed to provide high accuracy and a reliable range of measurement products. Advanced technologies such as interferometers, diffraction and cameras ensure high speed and high accuracy. Its sensors are useful on-line and off-line for non-contact measurement applications. On the Cersa stand will be: Fine wire surface quality measurement : SQM. After thorough development, Cersa’s SQM instrument is almost ready for sale. Measuring 256 dots around the wire at 200,000 images per second, it works on any wire below 2mm diameter, including drawn, plated and enamelled. Fine wire diameter measurement : LDS, for fine wires down to 5µm diameter, provides highly accurate measurement for in-line or lab measurement. Cersa will launch its LDS-H at 40kHz on three axes for very fine cables down to 50µm diameter. Fine cable high-speed diameter measure- ment : LPS-H for measurement at 40,000 samples per second on each of three axes for diameter, lump and neck down detection, all-in-one instrument up to 20mm diameter. Optical fibres : A complete line of measurement instruments for full in-line quality certification. With more than 400 drawing towers fully equipped, and technology at the top level for high-speed draw-towers, LIS-G, NCTM, CM5 and AIR cover the full need for fibre drawing control, from the bare fibre (diameter, airline, spinning, defects, accurate tension) CeramTec GmbH – Germany Website : www.ceramtec.com Cersa – MCI Stand: W1D01

The robust ceramic materials ensure higher wire quality, minimal wire breakage, and reduced maintenance costs. Ranging from wires made of precious metals like gold in hi-fi speaker cables to the extensive cabling in the advancing e-mobility sector to high-voltage lines – wires are everywhere, performing their duty unseen. However, by the time a wire makes it onto the market in the desired thickness and quality, it has already undergone a genesis under the harshest conditions. CeramTec’s ceramic materials are standard in the production of copper and non-ferrous metal wires worldwide. Nothing but the highest tensile forces are sufficient when it comes to turning raw wire into fine wire. One of the reasons machine manufacturers in the industry sector look to the yellow ceramic is because it is explicitly requested by end customers. The surfaces of the ceramic materials are highly resistant to thermal and chemical influences. Machine components such as drawing rings, capstans, eyelets, form elements, guide rolls or ring segments are more able to withstand the constant high stress that they are subject to in the process. Users benefit from the high level of dimensional accuracy with which wires can be manufactured. This results from the particle size of the materials. It can be defined so exactly that it enables every surface to be manufactured precisely with those special properties that will be best suited to the requirements of the application in question. Processes in which CeramTec tools are used suffer from very little wear thanks to the robust properties of the ceramics. This means longer maintenance intervals, which in turn results in lower maintenance costs. Silicon nitride, zirconium oxide and aluminium oxide are the most common ceramic materials used in the wire manufacturing industry. After the shaping and firing process, the material possesses a diamond-like hardness. The fine polish after grinding is fundamental for the high quality of the manufactured wires. Tools treated in this way are distinguished by a very large contact area. This makes it possible to apply a constant torque on the wire and at the same time precisely adjust the slip factor. This enables consistent wire ❍ CeramTec advanced ceramics in use

All the products are the result of customer demand and close cooperation between industry experts and Cersa engineers to improve continuous in-line production checks for material saving and quality certification. Cersa-MCI – France Website : www.cersa-mci.com ❍ Measurement solutions from Cersa Condat will share its long-term expertise in wire drawing lubrication. Among a wide range that includes non-reactive and reactive coatings, dry powder lubricants, oils, pastes, greases, protection and degreasing products, the company will display its new lubricants for the Asian market. To reduce residues, limit costly degreasing operations and improve the quality of the wire, Condat’s laboratories have developed a new range of water- soluble lubricants. Vicafil SL soluble oils have been formulated to meet the latest wet drawing requirements. Enhanced with biocide and anti-foaming properties, this range can be used for drawing low- or high-carbon steels with various surface preparations, from bare or pre-drawn wire, acid-pickled and phosphate-coated wire, to galvanised wire. The Vicafil SL range is easy to put in solution and leaves a clean surface finish. It also ensures a long bath life. Steel cord production requires a high level of quality and finish on the wire together with high-speed production. New Condat developments are oriented to answer those constraints, including for extra high tensile steel cord wire production. ❍ New lubricants for the Asian market will be on display on Condat’s stand Condat Lubricants Stand: W1D41
