About ATESTEO
ATESTEO is a service provider specializing in drivetrain testing with headquarters in Alsdorf near Aachen. The company tests transmissions and complete drivetrains – from combustion and hybrid to electric drives – on more than 200 of its own test benches in Germany, the USA, China and Japan. The service portfolio includes NVH testing, environmental simulation, brake testing, vehicle testing and road trials, as well as engineering services for prototype optimization. In its own DIN EN ISO 9001 certified machining facility in Alsdorf, prototypes, metrology equipment and test bench components are manufactured: CNC milling on 3- to 5-axis machining centers, CNC turning, cylindrical and surface grinding, keyway slotting, welding and assembly, from single parts to small series. Materials processed include steels, non-ferrous metals, plastics and titanium, in particular for torque measuring shafts and flanges. The portfolio is complemented by a DAkkS-accredited calibration laboratory, telemetry and high-voltage temperature measurement systems, as well as maintenance, repair and commissioning of metrology equipment. Customers come primarily from the automotive industry, automotive supply sector and mechanical engineering.
