Factory Equipment Surface Technology

No wastewater is produced during washing and degreasing thanks to the company’s own vacuum water treatment plant. Treated water is temporarily stored in tanks and fed back into the process as required. There are also no environmentally harmful color residues in the powder chamber. Powder dust that does not adhere to the workpiece is extracted, cleaned and fed back into the coating process. In this way, the high-quality RAUCH surface finishing contributes to the protection of people and the environment at the same time.

In powder coating, electrically conductive materials are coated with powder coating. The coating plant consists of a surface pretreatment, an electronic coating zone, and an intermediate and a main dryer. The parts to be coated are transported by a conveyor system during the treatment process. Typical substrates for powder coating are steel, galvanized steel and aluminum. The powder coating particles are first fluidized. In the process, the powder must be cleaned of fibers, coarse particles and dirt.

• By using a special pleat spacing technique with polyester-based filter media, the filter elements achieve improved cleaning behavior. The favorable flow conditions lead to an increase in efficiency of up to 44 % and utilization of the entire filter surface of the filter cartridge.
• The cleaning process is favored by the embossed spacers in the filter material in the form of a cam. There is no blocking of the pleats, the air passage is constantly ensured to the highest degree and the filtered medium can be perfectly back-cleaned from the pleat to ensure an extremely low differential pressure.
• The filter material achieves good separation performance in the fine dust range and represents a cost-optimized solution for applications where electrical charges of the dust filter cake have to be dissipated.
