Customization scope
The equipment configuration is defined around your project requirements.
Overview
Performs the second sealing step of pouch cell production: after electrolyte filling and wetting, the cell is placed in an aluminium vacuum chamber, residual gas is evacuated through a piercing mechanism and the pouch is closed by heated brass sealing heads. Chamber closure and head travel are both cylinder driven on linear guide bushes, which maintains seal parallelism.
Key features
- Copper sealing heads for efficient heat transfer and reduced energy consumption
- Sealing pressure regulated by an air pressure valve to suit different processes
- Upper and lower heads driven by cylinders on two linear guide bushes for parallelism
- Automatic piercing mechanism integrated in the chamber
- Cylinder-driven chamber lid with linear guide bushes for vacuum integrity
- Adjustable for different cell formats with simple changeover
- Compact, low-weight construction
