The two plants in Rheinau and Kehl developed in slightly different directions in regards to their products, markets, and customers. This led to both plants being legally separated and turned into separate companies. From this point in time there was RMA Rheinauer Maschinen und Armaturen KG and RMA Maschinen und Armaturen Kehl KG. With a total of 390 employees and a production and storage area of 43,000 square metres, a total turnover of 95 million DM was achieved.
