Overview
A vacuum pre-sealer for pouch cells. The filled cell is placed in the vacuum box, air is evacuated to the set level, and the top and side edges are heat sealed while vacuum is held. Sealing under vacuum removes gas from the pouch before formation and gives a uniform seal bead.
Key features
- Vacuum box combined with a pneumatic heat-sealing assembly
- Sealing heads rated to 250 °C with independent upper and lower settings
- Vacuum adjustable to -90 kPa with a digital pressure switch
- Sealing time, pressure and temperature set from the control panel
- Separate control box for bench-top installation
- Low air consumption per sealing cycle
