SFZ-200 Top-side Heat Sealing Machine

The SFZ-200 Top-side Heat Sealing Machine is a compact laboratory heat sealer designed for sealing aluminium-laminated pouch films used in lithium-ion pouch cells, polymer cells and supercapacitor case preparation. It applies controlled heat, pressure and dwell time to form a consistent seal across the pouch edge, helping researchers prepare cells before electrolyte filling, final enclosure or intermediate assembly steps. The machine configuration is suitable for both top sealing and side sealing when working with pouch films and tabbed cell structures.

Working Principle

The system uses a heated sealing head with a soft sealing blade arrangement. In this design, copper provides efficient heat transfer, while the upper contact structure incorporates aluminium and silicone rubber components to improve sealing compliance across laminated pouch materials. During operation, the user sets sealing temperature, time and pressure, then places the pouch edge between the sealing bars. The combination of thermal energy and pneumatic pressure softens the laminate interface and creates a reliable bonded seal.
