Ultrasonic Metal Welding Machine (4200 W)

This ultrasonic metal welding machine, delivering 4200W of power, is developed for high-precision joining applications across advanced battery production lines, including prismatic aluminum case cells, solid-state batteries, metal lithium systems, and zinc-ion configurations. It is also compatible with dry electrode preparation and glovebox stacking processes. The system employs controlled ultrasonic vibrations to create solid-state metallurgical bonds without introducing external heat or filler materials, ensuring low electrical resistance and consistent joint strength. Its construction supports robust, repeatable welding of copper, aluminum, nickel, and other conductive foils or tabs commonly used in battery assembly. The equipment is suited for both R&D-scale prototyping and small-to-medium production runs, offering stable performance in dry or inert gas environments. While specific technical parameters are not detailed here, the unit’s power class and design focus on reliable, high-quality metal joining for evolving energy storage and electrochemical device manufacturing.
