Case Studies

While relocating its production line, a manufacturer of high-end sealing systems for powertrains in China considered a new wastewater concept. For the company, which specializes in precision seals and modules made of elastomer, metal, and plastic materials for the automotive industry, environmentally compatible processes and the efficient use of water as a resource are important aspects.

At Rabas Protec in Saint Nazaire, France, aluminium parts are produced, mainly for the aerospace industry. After mechanical processing, the parts are anodised and painted to protect them from corrosion. To do this, the surfaces of the parts are first prepared in degreasing baths, followed by sodium and acid pickling. Before the surface treatment, an NDT test can be carried out using dye penetrant testing. The final step is painting.

The demands placed on components in the automotive industry are becoming more and more stringent - as a result, the requirements placed on manufacturers and suppliers in terms of cleanliness are also increasing.

In the course of the expansion of production at IWIS in Landsberg and the acquisition of new parts washing systems, project manager Henning Fritz and the person responsible for the parts washing systems also considered a new wastewater treatment system. Due to the good experiences with the company H2O GmbH at the location in Munich and a very successful, quality-improving test run in their own production, the decision to use a sustainable VACUDEST vacuum distillation system for this site as well was made.

In November 2013, AUDI AG opened its new production facilities in Münchsmünster. In the Industrial Park in Münchsmünster, located approximately 30 kilometres to the east of the main plant, an Audi competence centre was created for the production of bodywork structural parts made of die-cast aluminium, hot and cold formed pressed parts, as well as chassis components.

Sustainable and economical production - this was also the wish of the company ZINKPOWER Coating Schopsdorf in Saxony-Anhalt. The company specialises in the powder coating of steel, hot-dip galvanised steel and aluminium components. The company opted for a VACUDEST vacuum distillation system for the water treatment process.
