Umicore Galvanotechnik GmbH in Schwäbisch Gmünd looks back on a 135-year tradition. Sustainability as a basic principle runs through all areas, from energy supply to personnel management.

Effect coatings look great, but usually place higher demands on the coater when it comes to coating. In the case of decorative panels in facade construction, there were strong visually perceptible color differences between the individual panels. Because two experts had already come to different conclusions, DFO was commissioned to determine the color shade.

When anodizing aluminum, maintaining the electrolyte temperature on the workpieces is a decisive factor for the quality of the surface treatment. Therefore, effective bath agitation is important. A hdraulic bath agitation system stabilizes the anodizing process while improving quality and efficiency.

Nearly 80 participants came to the Corrosion Protection Summit in Frankfurt. Here there was news about coating systems, testing standards and exciting guest lectures directly from the industry, from the screw manufacturer Nedschroef to Porsche.

In large and highly automated painting plants, many different process steps and tasks have to be brought into as ideal a sequence as possible. An MES system specially optimised for such plants offers the best prerequisites for this.

At a Swiss manufacturer of household appliances for the upper price segment, everything from the sheet metal to the finished product is produced in-house. In order to further develop the standard, the company invested in a new powder enamelling plant.

At the site of the Bochumer Verein Verkehrstechnik (BVV), wheels for rail vehicles are forged and sometimes combined into complete wheelset systems. To meet the increasing demand, a highly efficient coating plant was installed in 2022.

ElringKlinger AG manufactures 350,000 transmission components and 130,000 service covers per year at its headquarters in Dettigen an der Erms. The demands on the quality of the parts are high - especially when it comes to cleanliness. This is where the AG company relies on a regional professional in contract degreasing.

The requirements for component cleanliness have steadily increased. This development confronts parts manufacturers and processors in all industrial sectors with new and more demanding tasks. The FiT guideline "Controlling Filmic Contamination" provides recommendations for optimizing the process chain in component cleaning.

When discussing the performance of anti-corrosion coatings, the word edge coverage is often mentioned. The term refers to the ability of the coating material to achieve a sufficiently high film thickness in relatively sharp-edged areas of the object to be painted.
