The hydraulic rod is used to fold both sides of the lithium battery at the same time. Combined with the sensor control of the hydraulic rod to perform hot pressing, the folding and pressing are carried out synchronously.

Benefits of technology

This technology enables simultaneous folding of both sides of the lithium battery, improving production efficiency, enhancing the folding and pressing effects, and ensuring the sealing and robustness of the battery packaging.
