Frequently Asked Questions
Q1: What cell formats does this cylindrical winding machine support?
The machine supports 18650, 21700, 32650, and 4680 cylindrical cell formats. Quick-change tooling allows fast switching between formats with minimal downtime.
Q2: What is the production speed and yield of this machine?
The machine achieves 15-25 PPM (depending on cell model and winding layers) with ≥99.5% yield (with qualified incoming materials).
Q3: How does the digital tension control system improve winding quality?
The fully digital tension system (2-20N range, ±0.5N accuracy) maintains consistent force on anode and cathode strips throughout the winding process, preventing wrinkles and ensuring uniform electrode density – directly translating to higher battery capacity and longer cycle life.
Q4: Can this machine be integrated with MES systems?
Yes. The machine supports standard Ethernet and RS-485 communication with full MES integration for real-time production monitoring, yield statistics, and fault alarm logging.
Q5: What is the difference between this fully automatic machine and semi-automatic winders?
This fully automatic machine operates unmanned 24/7 – from electrode feeding to finished core handling. Semi-automatic winders require manual intervention for loading/unloading and typically achieve lower throughput (5-10 PPM vs 15-25 PPM for this fully automatic model).
Q6: What materials are compatible with this winding machine?
The machine supports graphite and silicon-based anodes, and NCM, NCA, and LFP cathodes. Electrode width ranges from 40-150mm with thickness 0.1-0.5mm.
