About Aartech
Aartech GmbH is a Swiss contract manufacturer for sheet metal fabrication, machining and system assembly based in Kleindöttingen, right on the German border. The company produces highly stressed components and complete assemblies, including turbine and turbocharger parts, valve and pump housings, control cabinets, machine enclosures and system assemblies for radiation therapy and laboratory technology. The process portfolio includes laser cutting, punching, press braking, forming, welding (including robotic welding), 3- to 5-axis CNC milling, CNC turning, surface and cylindrical grinding as well as heat treatment, surface treatment and climate-controlled or dust-free assembly. Materials processed include steel, stainless steel, aluminium, copper, titanium and nickel-based alloys such as Inconel and Hastelloy. Customers come from energy technology, medical technology, semiconductor technology, transport technology, mechanical engineering, process engineering and research. The company emerged from predecessor operations of BBC/ABB and is certified to ISO 9001, ISO 13485 and ISO 3834-2.
