1.XN-SFZ200 Battery heat sealing machine is a compact heating sealer for sealing aluminum-laminated films during pouch cell (polymer Li-Ion cell) case preparation.
2.The battery heat sealing machine adopts soft sealing bar, The sealing is copper in bottom and aluminum and Silicone rubber piece on top. So it can be used for both top and side sealing for
pouch cell.
3.It can prepare the pouch cell for the injection of electrolyte by sealing the side and top of the pouch cell with tab.
Working principle
It is transmitted to the head (copper) through the resistance heating tube, and acts on the sealing material (aluminum laminated film) of lithium battery by using the heat conduction effect. Under a certain pressure, it is heated to become soft and close to the melting state to complete the compression fusion joint. The top seal and side seal can be realized without changing the mold.
Features
* Upper and lower sealing blade temperature can be controlled separately, temperature is
adjustable and digital display by thermostat.
* Sealing head is made from copper with good heat conduction.
* Pressure gauge is embedded and easy to observe the sealing pressure.
* Firmly sealing.
* Safety protection cover is included to avoid scalding.
* Sealing time can be adjusted by timer.
* The sealing blade length is 200mm, battery case < 200mm can be used without replacing
sealing blade.

🔧 Recommended Sealing Workflow
For a complete pouch cell sealing process, the following combination is suggested:
- A. Compact Heating Sealer – for top & side sealing with tab
- B. Vacuum Sealing Machine – for pre-sealing in glove box after electrolyte injection
- C. Final Vacuum Sealing Machine – for vacuuming and second sealing with automatic puncture and degassing
💡 Cost-Effective Option: If budget is limited, using machine A + B can also meet basic sealing requirements.
