Springs that move the world
Monninger Federn GmbH is a medium-sized family-owned company from Lauterstein in Baden-Württemberg with 70 employees, specialized in the design and manufacture of technical springs and wire bending parts. The manufacturing program comprises compression springs with wire diameters from 0.2 to 8 mm, extension, torsion and leg springs as well as wire bending parts and flat form springs, which can mostly be produced without special tooling. On a modern CNC machine fleet, all competencies of spring production are bundled under one roof: comprehensive material warehouse, further processing and assembly in-house, external finishing by specialists, and TÜV-Süd-certified quality assurance with 100 percent series inspection. The focus is on processing corrosion-resistant materials such as stainless steel (including 1.4310 and 1.4571) as well as special materials such as Hastelloy, Nimonic and Inconel; in addition, carbon spring steel, brass, copper, aluminium, titanium and other materials are processed. The products are used in the automotive and aerospace industries, elevator technology, medical technology, wind energy, plant and apparatus engineering, mechanical engineering, and in consumer products such as coffee machines.
