(Pre-Sealing) Vacuum Pouch Sealing Machine is used for vacuuming and hot-pressing pre-sealing of pouch cell batteries after they are filled with liquid and left to stand.

The electrolyte in the battery needs to be sealed under vacuum conditions to ensure the safety and stability of the battery. The lithium battery vacuum pouch sealing machine can effectively reduce the gas content during the packaging process and improve the quality and performance of the battery.
It can also improve production efficiency, reduce manual operations, and reduce costs.
