The Otto Müller Schnellradiale factory was purchased in 1974 and rebranded as JW FROEHLICH Maschinenfabrik GmbH Plochingen. The range of radial drilling machines that came with the factory was initially expanded to include a thread rolling machine. In 1977, JW FROEHLICH started to develop, design and produce MOD3 automation for hot test systems, which were commissioned by Daimler and Opel. In 1979, the existing administrative building was replaced by a larger office building.
Development, design and production of vacuum drying units and search gas leak test facilities for hermetic compressors and heat exchangers began in 1987. In 1989, the factory was substantially extended, a design office was integrated and the company started to design and manufacture leak test rigs and assembly machines for the automotive industry. Neighbouring premises Drommel were purchased in 2002, with the building located there torn down and the plot rounded off.
