Ultrasonic deep drawing technology, developed by Fraunhofer IWU, reduces friction by 20% and extends tool lifespan. By incorporating ultrasonic vibrations into deep drawing processes, the team has successfully controlled sudden stresses, allowing for more efficient and effective forming. This technology has the potential to revolutionize the manufacturing industry, particularly in the production of pipes and fittings. The focus is currently on applying this technology to cell housings for high-voltage batteries in electric vehicles. The patent application for VibroDraw has been filed, showcasing the potential for significant advancements in industrial forming processes.
