About MÜLLER Gefrees
Müller Maschinen und Anlagen GmbH & Co. KG in Gefrees (Upper Franconia) has been developing and manufacturing machines and systems for punching and forming technology since 1913. The portfolio includes eccentric presses, straight-side double-column presses, punching automats, knuckle-joint presses, servo presses, CNC notch presses, CNC punching technology, feeding technology such as reels, strip levelers, roller feed and clamp feed systems as well as 2D/3D transfer systems. In special machine construction, customer-specific systems are built, including punching-bending centers for technical springs, notch pressing systems for small motors, assembly lines, deburring systems for forged parts and complete systems for the production of cutting-off and rough-grinding wheels. More than 50% of revenue comes from customer-specific punching and forming systems; around 25% of employees work in development. In addition, the company offers its own machining, service, maintenance and testing according to BGR 500 (UVV), spare parts manufacturing also for third-party products, and general overhauls of used machines. Materials processed include sheet metal, steel, aluminum profiles, electrical steel sheet and plastics.
