SFZ-200 Top-Side Battery Heat Sealing Machine

The SFZ-200 Top-Side Battery Heat Sealing Machine is a compact benchtop pouch-cell sealer designed for aluminium-laminated films used in polymer lithium-ion pouch cell preparation. It is intended for laboratory and pilot-scale battery research where repeatable thermal sealing is required during pouch case preparation, tabbed pouch assembly, or pre-electrolyte processing. The machine supports both top sealing and side sealing, making it useful across a wide range of battery testing and electrochemistry workflows.

Working Principle

The system forms a seal by combining controlled heat, dwell time and pneumatic pressure across laminated pouch film. SFZ-200 describes a soft sealing blade structure in which the lower blade is copper for efficient heat transfer, while the upper contact assembly includes aluminium and silicone rubber to improve conformity across the pouch surface and around tab regions. Users can adjust sealing temperature from room temperature to 250 °C, sealing time from 0 to 99 seconds, and sealing pressure from 0.5 to 0.7 MPa to suit pouch design and laminate thickness.
