Sealing Prismatic Cell

Customer requirement:

  • Sealing insulator film to terminal cover, sides and bottom with spot sealings

Our solution:

  • One heat-sealing tool per seam
  • Multiple heat-sealing tools with one circuit system possible
  • Compact design of the heat-sealing tool tailored to the specific application

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 without need for an external sensor
✓ Minimal heat impact on the product
✓ Fast heating and cooling of the system, due to the low mass of the heat-sealing band
