About FerTech
FerTech AG is a company specialized in CNC manufacturing, based in Lengnau in the Swiss canton of Aargau. Since 2001, the company has produced complex turned and milled parts, prototypes, individual parts as well as small and medium series to customer specifications – also as rush orders. The machine park comprises 3-, 4-, 5- and 6-axis CNC milling machines, turn-mill centers for complete machining, and CNC lathes with driven tools; tolerances down to ±0.01 mm are possible. Materials machined include aluminium, copper, brass, structural steel, high-alloy and heat-resistant steels, difficult-to-machine materials such as Hastelloy X and Nimonic, titanium, and engineering plastics. In addition to machining, FerTech offers design, planning and material procurement, surface treatment, and the assembly of ready-to-install assemblies including functional testing. Customers come from the energy, environmental technology, mechanical engineering, transport and consumer goods industries. The company is ISO 9001 certified.
