Solving the cleaning system dilemma

When looking for a cleaning system for wires, cables, etc, one is often faced with a dilemma. Which method, in general mechanical or wet-chemical, is suitable for the desired surface quality? In addition, your budget or your available space might be limited. of manufacturers of inline cleaning systems as well as the current market solutions are manageable. The appropriate method is still difficult to determine at first glance. And as a result of this difficulty, there is often an attempt to construct and implement your own solution only to find that the outcome is, despite intense input of time and material, inadequate. Where to begin the search? Basically, the definition of the cleaning target and the analysis of the surface texture should be at the beginning of the search. Only when these points are defined, the choice of the suitable method, and if necessary a suitable cleaning agent, can be carried out. Usually a subdivision in “mechanical cleaning” and “chemical cleaning” is made, whereby nearly all mechanical cleaning methods can be combined with the chemical cleaning. the contamination is removed by the mechanical frictional force of normally solid cleaning materials such as brushes, textiles and microfibres. To remove gross contamination from the wire surface, cleaning with brushes or textile materials is very effective. surface characteristics of the wire are far from ideal due to, for example, fine cracks and defects, these methods quickly reach their limits. Chemical cleaning means in most cases that a fluid exposure performs the cleaning. The performance of these methods is considerably improved by increasing the velocity of the liquid by means of high pressure, ultrasonic or steam relaxation. However, today the range With mechanical cleaning, However, since the

or steam, can substantially meet the challenging task of removing dirt even from the smallest surface defects. Finally, the effectiveness of the cleaning process depends on how targeted the cleaning power (force or impulse) can be applied to the contamination for a certain time. all parameters is necessary. Since the choice of the appropriate cleaning method is determined by many other factors, a comprehensive analysis of all parameters should be undertaken. This is precisely the approach that GEO- Reinigungstechnik GmbH (GEO) has selected. For the last two decades GEO has explicitly dealt with the cleaning of continuous profiles such as wires, ribbons, strands and cables. GEO offers a complete range of ultrasonic, high-pressure jet nozzle, steam and mechanical wire cleaning systems both for single wire and multi-wire applications. GEO has completed the cleaning of welding wires after the drawing process by systems for coating with welding wire finish and subsequent quality control. The procedures can be tested under near-production conditions at GEO’s test laboratory and from the knowledge gained suitable solutions can be selected and implemented.
