Our solution for impulse sealing will convince you
The optimal production process in sealing battery cell film
Vacuum sealing
The pouch cell is sealed watertight using ROPEX impulse sealing technology and is filled with electrolytes under vacuum. This produces gas, which is forced into a gas bag under external pressure. The area between the cell and the gas bag is then finally sealed with ROPEX impulse welding technology.
Piercing the gas pocket
The gas pocket can be tapped and the gas extracted after it has been securely sealed
Separated gas bubble
The gas bubble is then separated. Due to the tight sealing seam, the pouch cell remains optimally protected even after separation.
Intermediates
ROPEX impulse sealing technology ensures that all sealed seams are tight even after the separation process, even under difficult conditions, and thus protect against moisture and oxygen
Folding process step 1
The edges of the seal are then folded and glued if necessary.
Folding process step 2
Further folding of the protrusions further reduces the size of the pouch cell.
Output
The end product is a securely sealed pouch cell that is ideally prepared for the subsequent aging process thanks to impulse sealing technology.
