About Lange GmbH
Lange GmbH is a family business founded in 1984, headquartered in Mehrstetten (Baden-Württemberg) with around 60 employees. Its core business is build-to-print manufacturing of turned and milled parts made from castings, steel and aluminium – from prototypes and one-offs/spare parts to small and medium production runs in lot sizes of 1 to 5,000 pieces. The product range includes complete machining including heat treatment of housings, connector plates and control blocks for mobile and stationary hydraulics as well as mechanical engineering components of all kinds. Production takes place on modern, partly fully automated CNC lathes and turn-mill centres (Mazak) as well as vertical and horizontal machining centres, complemented by honing, single-disc lapping, high-pressure water-jet deburring, cleaning, laser marking and pre-assembly. Projects are designed in 3D (CAD/CAM) and transferred directly to the CNC machines. On a production area of 2,850 m² on a 7,000 m² site, ready-to-assemble components are produced under DIN EN ISO 9001 certified quality management. Since 2021, the company has been investing more heavily in automation and robotics.
