Credit: Fraunhofer IWU You can find them in many household appliances, building technology, and countless pipe and hydraulic lines: small, cylindrical parts manufactured through deep drawing processes. The material is under strain during shaping. Potential consequences are unwanted thinning, surface damage, or cracks. The solution is ultrasonic vibrations—these reduce friction significantly within the material and in contact with the tools. In the VibroDraw process, Fraunhofer IWU, in collaboration with MARK Metallwarenfabrik GmbH and DEVAD GmbH, has successfully integrated ultrasonic vibrations into industrially relevant deep drawing processes with cycle rates of up to 500 strokes per min ...
