wire 2014

has become the preferred feedstock especially for: • fine and multi-wire drawing where ductility requirements are most demanding • enamel wire production where surface finish is of utmost importance • continuous rotary extrusion where tool wear rate is a crucial factor Absence of harmful emissions and need for waste treatment reduces the environmental footprint of Upcast casting lines. In addition to the small environmental footprint other Upcast GREENerCAST characteristics are clear: low lifecycle costs, easy variation of output, use of scrap in the process and unique upgradability. Upcast OY – Finland Website : www.upcast.com WTM will show all visitors the results of its most recent research. Inspired by the direct experience and the production needs of customers, new solutions have been developed by its engineers for enhancing the production performance and possibilities of its taping equipment. In particular, on display will be: • A working horizontal line with twotaping modules wrapping polyimide +PTFE, typical application for aerospace cables. They will be equipped with new 150mm and 200mm taping heads for cross wound spools, that can run up to 3,000rpm, fitted with a high sensitivity tape tension control. These heads are also suitable for any other kind of tape. For the quality control on the taping process, the Visio System will be installed and working. • A working vertical taping line suitable for a revolutionary mica tape, an innovative tape for the production of fire resistant and fire retardant cables. The advantages of this new technology are no tape-flicking effect, reduced quantity of tape needed, increased production efficiency in the following extrusion process and smaller thickness of the required external insulating material; all this resulting in a greater efficiency in the cable installation. The line is completed with translating take-up and pay-off, allowing reduced footprint. In addition to these machines, WTM will illustrate a new line developed for the application of metallic tapes on coaxial cables suitable for high frequencies, and all its production range, together with taping WTM Srl Stand: 11E77

lines for other applications. These include single twist bunching machines, sintering ovens, and machines for testing cables etc. WTM Srl – Italy Website : www.wtmachinery.com

The original Upcast continuous casting technology allows casting of top quality copper and copper alloy rod in the most cost efficient way. It is a simple process with easy operation through an advanced control system, with reliability built on 40 years of consistent development work, operational experience and excellent customer service. There is a wide range of alloyed coppers and copper alloys that can be cast with Upcast. These include, as an example, silver bearing and phosphor-deoxidised coppers, brasses and bronzes; copper magnesium may soon become part of the range. As new applications for copper alloys are being developed and new types of copper alloys emerge, the utilisation of Upcast technology within the copper alloys field is rapidly increasing.

Novel, intelligent and cost-efficient solutions for in-line measurement and control of wires and cables are going to be the focus of Zumbach’s stand at wire 2014. New linear sensor technology allows cost-effective, synchronous multi-axis measurement of diameter and ovality in any cable, tube and hose extrusion process. Unique measurement technology for products up to 200mm outside diameter: • A new product line with two-coloured LED light sources allowing simultaneous scanning in each axis (XY) and thus trouble-free measurement even with product vibration. This new concept allows even a four-axis measurement of products up to 54mm diameter • Integrated extraneous light filters prevent occurrence of measurement errors that to date seemed unavoidable • Perfect performance even with reflective surfaces thanks to the use of different colour lighting for each measurement axis The high-tech ultrasonic system Wallmaster offers application-specific solutions for measuring and monitoring wall thickness. The measuring data processor with touch-screen display gathers data and fully automatic quality control. In combination with ultrasonic UMAC ® scanners and various ODAC ® diameter measuring gauges as well as error detectors, the measuring and monitoring scale can be expanded to outside and inside diameter, statistics, SPC and processor communication. Using Zumbach’s Wallmaster measurement and control systems, manufacturers can economise their expenditure of raw materials. The novel construction (patent pending) of new ultrasonic scanners is going to be a highlight: the transducers can be either individually or simultaneously adjusted to the best possible measuring position within seconds. The scanners cover an outside diameter up to 180mm and represent a smart and simple solution for full non-contact, in-line eccentricity and wall thickness measurement of cable jackets, tubes and hoses.

Upcast rod production lines are of modular design. Both single and double-furnace configurations are possible. With a double-furnace configuration – having separate melting and casting furnaces – it is possible to reach 40,000tpa output, while 12,000tpa is possible for a single-furnace configuration. Different rod sizes can be cast simultaneously and the output and product mix can be adjusted. Upcast lines are extremely flexible and tailor-made to match the needs of each specific customer. If scrap – clean and dry – forms a significant part of the input material then a double-furnace configuration should be the preferred choice. The majority of delivered Upcast lines are for Cu-OF rod. The most common cast rod diameter is 8mm which is the standard size within the cable and wire industry. Rods with bigger diameters are used for manufacturing a variety of products eg bus-bars, trolley wires, electroplating anodes etc. Upcast Cu-OF rod is well-suited for all electrical applications and ❍ Cost efficient solution from Upcast
