Customer requirement:
- Sealing tabs
- Dense seam
- Compensation of layer jumps
- Seam directly at the cavity of the pouch cell
Our solution:
- One control circuit per seam
- Double-sided heat
- Soft silicone profile under the heat-sealing band to compensate the height difference in between the pouch film and the tab
Sealing in two steps:
- Sealing of three sides of the cell including tabs
- Sealing the final fourth side after degassing
Customer advantages:
✓ No warm-up phase of the system required, seam tight from the first cycle
✓ Repeatable sealing results from cycle to cycle
✓ Fast, precise control as no external sensor is required
✓ Minimal heat impact on the product
✓ Independent temperature control of each heatsealing band
✓ Fast heating and cooling of the system, due to the low mass of the heat-sealing band
