About LOEST Präzisionsmechanik
LOEST Präzisionsmechanik GmbH is a contract manufacturer of precision components, run as a family business in its fifth generation in Duderstadt since 1908. Production encompasses high-precision 5-axis CNC milling, CNC turning up to Ø 300 mm and complete machining of complex components on modern turn-mill centres in a single setup – from prototypes through small and medium series to large-scale production. Materials machined include aluminium, steel, stainless steel, titanium, plastics and special materials. In addition, the company offers surface treatments such as vibratory finishing, shot peening and electroplating, ultrasonic cleaning, laser marking, assembly of complete assemblies, custom packaging and Kanban solutions for warehousing and supply. The components go into medical technology, metrology and control engineering, mechanical engineering, analytics and the high-tech industry; customers include Blaupunkt, Bosch and Otto Bock. The site at Breiter Anger 17 offers around 1500 m² of production space with a modern machine fleet and a 3D coordinate measuring machine.
