 Products Description 

Battery Ultrasonic welding machine commonly used The laboratory battery research will use an ultrasonic welder to complete the welding of tab-tab, tab-electrode, and electrode-electrode. The ultrasonic mold welding head can be changed to complete the welding of pouch cell battery (tab-electrode welding) and cylindrical battery welding (cap-tab welding)

Ultrasonic welding machine is easy to operate, has a solid welding structure, and is stable and safe to use.

Ultrasonic welding principle: Ultrasonic metal welding machines(Battery Welding Machine) are used in the battery industry at 24.5-25.5KHz. The principle is to use the energy generated by ultrasonic high-frequency mechanical vibration to weld the same or different non-ferrous metal materials. During the welding process, no current is transmitted to the work. It does not input high-temperature energy into the work, but only performs cyclic vibrations on the surface of the workpiece at a high frequency of 24.5-25.5KHz, and applies corresponding pressure to the workpiece to form a solid combination between the workpieces to achieve the welding effect.
