Highest weld quality: process visualization and process stability provide for product safety and repeatability. Small footprint for easy integration into production lines. Ultrasonic metal welding is the ideal solution for maximum quality in production. For our customers, we assume the role of both consultants and application problem solvers with regard to the ultrasonic joining of nonferrous metals.
In addition to leading-technology products, we provide excellent, in-depth application services for solving welding tasks, particularly taking into account the qualitative and economic aspects.
A typical lithium-ion battery (LIB) uses copper foil as the anode and aluminum as the cathode. The welding of typically 20 to 60 foils to each other requires a high level of joining technology with long time process reliability. Burrs or cracks have to be avoided completely.
As more and more products contain rechargeable lithium-ion batteries (LIB), the battery manufacturers are aiming for ultrasonic welding as reliable battery assembly method. The specifications of the process demand a strong electric contact and no particles on the sealing film of the tab.
