Pouch Cell Formation and Capacity Grading Equipment with Hot‑Press Clamps – High‑Precision Pouch Cell Hot Press Pressure Formation Machine for R&D & Production
What Is a Pouch Cell Formation and Capacity Grading Equipment with Hot‑Press Clamps?
This equipment performs the critical formation process for polymer pouch cells under simultaneously applied heat and pressure. The formation step activates the cell and builds the SEI (solid electrolyte interphase) layer, while hot pressing improves electrolyte wetting, reduces cell thickness, and ensures flatness. Our compact machine integrates hot‑press JIG fixtures and precision charge/discharge electronics into a reliable, bench‑top or standalone system.
The incoming cell dimensions are as follows:
single-ended dual tabs (customizable based on customer-provided battery dimensions).
