Precision Mechanics Since 1970
Louis Wiedmann SA is a Swiss family-owned business specializing in precision mechanics, based in Neuenburg (Neuchâtel). The company manufactures prototypes, small and medium series, jigs, special tools, and complete mechanical assemblies as contract manufacturing. The value chain includes material procurement (including exotic alloys such as Inconel, Hastelloy, and Tungsten), 3- and 4-axis CNC milling, CNC turning, facing, assembly of turnkey solutions, and surface and heat treatments through a certified partner network. We process aluminum, steel, stainless steel, titanium, copper, bronze, brass, and technical plastics with tolerances up to ±0.005 mm. Customers come from microelectronics, automation, specialized machinery, pharma and medicine, watchmaking, scientific research, as well as aerospace – including the ESA for satellite structures and Ariane components. Delivery is made throughout Switzerland, to France and Germany.
