This equipment is mainly used for pre pumping, hot pressing and sealing of small and medium-sized) flexible packaging battery cells after liquid injection and standing.

technological process:

The equipment has upper and lower cavities to form a closed working space. After the battery is put in, the air in the cavity is extracted to form a negative pressure state to eliminate the air in the cell; Then, the double-sided heating head uses the heat conduction effect to act on the packaging material (aluminum plastic film) of lithium battery to heat and fuse them together to seal the cell.
