The medium-sized precision mechanics company from the Würm valley
radotec is a medium-sized precision mechanics company based in Krailling near Munich, specializing in high-quality precision turned and milled parts. Based on drawings or CAD data, ready-to-install components, assemblies and prototypes are produced from semi-finished stock or customer-supplied blanks. The range of services includes CNC milling (3-, 4- and 5-axis, parts up to 5000 mm), CNC turning with main and sub-spindle, grinding to IT3, honing and lapping, welding (TIG, MAG/MIG) and brazing, surface treatment as well as additive manufacturing of plastic parts. In addition, the company offers design and development in CAD, sample and device construction, and the assembly of structural and sub-assemblies. Customers include companies from medical technology, aerospace, the automotive industry, and the electronics and chemical sectors. All manufactured parts undergo quality control; the company is certified to DIN EN ISO 9001, ISO 13485 and ISO 14001.
