What is Second Sealing?
In pouch cell manufacturing, second sealing (also called final sealing) is the critical process performed after cell formation. During formation, gases are generated inside the cell. These gases must be released before the final hermetic seal is applied. The second sealing process typically involves:
- Puncturing the pouch to release internal gases
- Vacuum application to remove remaining air
- Final heat sealing under vacuum conditions
Our GN-HS200F vacuum sealing machine integrates all these functions into one compact, easy-to-use system.

How This Vacuum Sealing Machine Works (Second Sealing Process)
Step 1: Cell Preparation
After formation, you place the formed pouch cell into the vacuum sealing machine. The cell contains internal gases that must be released before final sealing.
Step 2: Parameter Adjustment
You adjust the sealing pressure using the pressure regulating valve to meet your specific process requirements. The copper head reaches operating temperature quickly and efficiently.
Step 3: Puncture
The automatic puncture function activates to release gases from the pouch cell. This critical step allows accumulated gases from the formation process to escape. Any waste electrolyte released during puncture is captured by the liquid recovery device, maintaining a clean work environment.
Step 4: Vacuum Sealing
The machine performs vacuum pumping to remove remaining air and gases, followed by hot-pressing packaging with the copper sealing head. The linear guide sleeves ensure precise, parallel sealing for a hermetic final seal.
Step 5: Completion
After sealing, the heads retract. You remove the finished cell, which now has a vacuum-tight second seal ready for testing or further processing.
