About mbw
mbw Rheinmünster GmbH has been part of the MWG Group and the mbw corporate group since January 2026, whose origins go back to the founding of mbw GmbH metallveredelung at the Lichtenau site in 1987. The company specializes in the surface finishing of metal and cast parts for industrial applications. At the Rheinmünster site, processes such as zinc plating (rack zinc-iron, alkaline rack zinc, alkaline barrel zinc), technical anodizing/anodization and bright passivation are carried out on manual and automatic electroplating lines. The annual capacity is around 2 million square meters of treated surface; parts up to 2,700 mm in length can be processed. The main customer industries are the automotive industry and mechanical engineering; according to the company, the group is the European market leader in chromium III coating. The group operates seven sites in Germany, six of which are in the field of surface coating, and serves customers domestically and abroad.
