About Magnetbau Schramme
Magnetbau Schramme GmbH & Co. KG is a family-owned company headquartered in Deggenhausertal (Baden-Württemberg) that has been developing and producing custom electromagnets since 1975. The portfolio includes solenoids, latching solenoids, double-stroke solenoids, switching solenoids, proportional solenoids, holding magnets, solenoid valves (pinch, seat and slide valves) as well as electromagnetic components such as clutches, brakes, magnetic coils, actuation systems and magnetic bearings. The value chain ranges from requirements analysis and concept development with CAD and simulation, via prototyping and validation, through to industrialization and series production with volumes of 10 to 500,000 parts per year. The in-house manufacturing depth includes CNC turning and milling, welding and soldering, in-house plastic injection molding, coil winding and final assembly in ESD and cleanroom environments. Customers come from safety technology, commercial vehicles, medical technology, food technology, hydrogen technology, mechanical and plant engineering, hydraulics, and energy and environmental technology. The company employs around 130 staff and produces more than one million parts annually.
