Herrmann Ultraschall has been a specialist in ultrasonic welding for decades and is presenting its new HiS VARIO welding system for metal welding such as copper and aluminum at Productronica. The system can be used as a manual workstation or automatically integrated into production lines.
Herrmann Ultraschall has been a specialist in ultrasonic welding for decades and has set high goals with the new weld system HiS VARIO for battery and terminal applications: in addition to process stability, these are shorter setup times and longer service life for the weld tools, above all.
The ultrasonic welding of nonferrous metals is an established process and is currently booming in connection with the growing market for lithium-ion batteries (LIB) – now the main storage source for electromobility. Herrmann Ultraschall has been a specialist in ultrasonic welding for decades and has now developed a new weld system for metals, the HiS VARIO.
Battery management systems (BMS) for cylindrical cells require precisely adjustable low weld forces. Herrmann has developed a new module which suits especially the welding of BMS to small cylindrical cells and finest materials, that can easily be integrated in existing production processes.
Booming electromobility and the growing demand for fast charging technologies result in increasing system voltages for electric vehicles. This requires powerful cable harnesses and power rails, which in turn requires larger cable cross sections and/or metal sheet thicknesses. The higher the cross section, the more difficult the welding. For this purpose, Herrmann developed the Ultrasonic Power Stack 12000+ as an extension for their HiS VARIO W ultrasonic welding machines.
With the common goal of safe and sustainable battery production, Herrmann is optimizing the ultrasonic welding process of battery cells together with CUSTOMCELLS. Initial results of the partnership show an opportunity for significant savings in terms of energy and rejects.
