Meeting tough demands

Silver Fox, a manufacturer of innovative, durable and time-saving labelling solutions, has launched its new range of Optical Fibre Flag labels suitable for data and telecoms, electrical and energy industries. A new range of optical fibre flag labels are now available with a choice of four label sizes. These durable, long-lasting labels are supplied as pre-cut A4 sheets designed for printing on any standard office laser printer with label templates available to download from the company's Labacus Innovator labelling software. Silver Fox – UK Saving time with new fibre flags Advanced RX5-Crosshead design keeps away process-deviations and increases quality and efficiency in extrusion-lines for micro-coaxial-, LAN- and standard power cables for automotive and non-automotive applications. Rosendahl Maschinen GmbH – Austria Fax : +43 3113 5100 51 Email : office@rosendahlaustria.com Website : www.rosendahlaustria.com Within the RX Crosshead Series – available in sizes from RX2 to RX110 – the latest product launch of RX5 made by Rosendahl meets the very wide-ranged demands in the field of cable applications between 0.1 and 5mm conductor diameter. Perfectly balanced polymer distribution, temperature- and pressure-profiles guarantee a smooth and stable melt-flow across the outlet zone. RX-Type Crossheads generally provide high-precision centricity, therefore preventing over-sizing cable wall-thickness. geometry ensures short residence time of polymer melt and enables a quick and easy change of colour or material. Easy handling is guaranteed by a compact and modular design, by high precision ball-centring over an adjustable and self-sealing tip-holder – or by the well-proven fine-tuning-centring which is not only requested especially in extrusion-lines for fibre-optic cables.

The BHW system incorporates new technology which enables normal plant water to be converted into the most unique 'micro-abrading liquid' agent used for cleaning of drawn wire, in-line, at high speed, at virtually zero energy consumption, providing extra-clean wire. Basically, it is a sensitive multi-layer displace/fine scrub/flush cleaning system, benefiting from water immersed high density ultra-fine brush bristles performing as porous long-life abrading pads that smoothly impact wire surface separating lubricant residue from base material, washing away dispersed contaminants by moving wire, exiting the unit clean of white-metal appearance. The BHW system provides the ultimate combination of simplicity and effectiveness: acid-free, caustic-free, without ultrasonic, without chemicals. Economical and environmentally friendly, the system provides significant process savings in production of clean H/C and L/C wires. The BHW wire cleaning system is used in the most demanding applications, allowing the highest cleaning speed, with all carbon steel wires (including 0.90%), mechanically descaled or acid cleaned, bare or pre-coated, drawn with calcium or sodium lubricants. The BHW system is particularly recommended for cleaning applications in which a conventional process is inappropriate, especially with

wires drawn upon severe conditions resulting in increased heat and burned lubricant tightly bound to the wire surface and embedded in microscopic cracks.

The BHW system cleans drawn wire from lubricant residue in applications prior to heat treatment or coating, including galvanizing, annealing, patenting, plating, welding (chain, mesh), painting, plastic coating, Al or Cu cladding, etc. In a typical application, the 2.6mm (0.102 in) drawn wire is cleaned in-line at 12m/s (2,400ft/ min) with 5 x BHW units, obtaining a very clean wire with remaining residue of 0.100-0.210g/m 2 , enabling direct galvanizing or other metallic or plastic coatings.
