EF-350 Turntable Vacuum Sealing Machine

EF-350 Turntable Vacuum Sealing Machine

Overview

The EF-350 Turntable Vacuum Sealing Machine is designed for final vacuum sealing of medium-size pouch cells after formation, and is also suitable for selected supercapacitor sealing workflows. It combines vacuum extraction, heat sealing, and rotary indexing in a turntable-based format to improve sealing consistency, throughput, and operator efficiency in battery research and pilot-scale production environments.

Principle of operation

The system uses a loading/unloading station and a sealing station arranged around a rotary turntable. After the pouch cell is positioned, the chamber closes to create a sealed cavity. The machine then applies vacuum, followed by hot-press sealing under controlled temperature and time conditions. Independent upper and lower heating head control helps maintain seal quality across aluminium-laminated pouch materials, while the turntable workflow supports repeatable positioning between cycles.
