Cleaning copper conductors before extrusion For the effective removal of contamina tion from the visible surface of wires, ca bles and pipes, GEO-Reinigungstechnik offers various aqueous and mechanical cleaning processes. After wetting, the surface is continuously wiped off in two process zones. To extract the vapours, the system is equipped with a flow sensor and an ex-protected extraction fan.

Its compact dimensions allow the system to be easily integrated into existing manufacturing processes.

The mechanical working LS-WST system is suitable for treating soft metals such as copper or aluminium. In the process zone of this wiping system, a woven textile tape wraps around the material surface. The continuously adjustable transport of the strip ensures that there is always a clean wiping tape in contact with the material to be cleaned. The short process zone and the short contact timebetween textileandmaterial, as well as the low friction force required for cleaning, avoids the accumulation of metal particles in the cleaning tape. GEO designed its twin LS-WST-LM device for the in-line cleaning of copper conductors before extrusion. For use with a volatile solvent to boost the cleaning, the system is completely enclosed. The solvent is evenly applied to the material using a gravimetric dosing unit that can be adjusted using a digital potentiometer. High precision spools Qunye spools achieve 100 per cent automatic laser blanking with high speed, high precision, no damage, smooth cutting surface and a tolerance guarantee, providing later robot welding and assembly with the necessary size matching. With high growth in its business, Qunye’s spools have been exported to 85 countries. Jiangsu Qunye Electrical Co, Ltd www.qunye.com.cn
