activated, part surfaces. It is with these requirements in mind that an expert in this sector has developed a set of new cleaning solutions. One of them combines wet chemical and low-pressure plasma cleaning in a single machine. Another innovation consists in integrating diverse applications for partial or full-surface cleaning or activation – e.g. atmospheric pressure plasma treatment, laser, CO2

and/or surface inspection operations – into one processing system. Tis toolkit enables operators to cover virtually all pre- treatment needs. In automotive manufacturing and its supplier industries, mechanical engineering, aerospace applications, precision and micro- mechanics, medical and optical systems, electronics and other fields of industry, component parts are subjected to cleaning to prevent quality problems in downstream processes and to ensure flawless product performance. In recent years, the focus in many industries lay on removing particulate contaminants. However, given new or modified production, joining and coating technologies as well as improved materials and combinations thereof, the elimination of film-type residue – e.g. of machining and preserving media, release agents, silicones, other auxiliary production compounds, or even fingerprints – is gaining increasingly in importance. Tis is because such residue can impair the quality of subsequent processes, such as coating, welding, adhesive bonding, sealing, painting or heat treatment. Ecoclean (formerly Dürr Ecoclean) addresses these evolving requirements with a number of new solutions.
ULTRA-FINE DEGREASING BY A COMBINATION CLEANING PROCESS For workpieces made of steel, aluminium, glass, ceramics and some other materials that are cleaned in batch processes – whether in bulk or arranged in part carriers – the company has developed a combination cleaning technique merging wet chemical cleaning with a subsequent plasma cleaning step. To this end, a low-pressure plasma cleaning operation is integrated into the wet chemical cleaning line. Since virtually all components needed for this cleaning

New cleaning solutions for altered requirements: innovative developments for ultra-fine cleaning and activation
technology – e.g. vacuum, measuring and control equipment – are already in place in the manufacturer’s wet chemical cleaning machines, the additional cost and engineering effort remains modest. Te advantages of the integrated plasma cleaning process in ultra-fine degreasing are substantial, including a high operating
flexibility, reduced process times, low investment and operating costs, plus very compact equipment build. Cleaning is initially performed as usual
by a solvent-based wet process, followed by vacuum drying of all workpieces. Te work chamber is then rinsed and its internal pressure is reduced to less than 1 millibar,
