Top 10 Pouch Cell Manufacturing Machine Suppliers in China (2025)

Why this guide

If you’re building or upgrading a pouch cell line, the hardest part is matching your product spec and ramp plan to the right equipment scope and vendor mix. This guide gives you a shortlist of reputable Chinese suppliers, a quick-compare table, selection criteria, benchmark budgets/lead times, and a copy-paste RFQ checklist so you can move fast with confidence.

What a modern pouch cell line includes

• Electrode prep interface: slitting, notching, dust control
• Stacking / Z-folding: precision layer alignment, tension control
• Tab welding & collection: ultrasonic/laser, CCD inspection
• Pouch forming & loading: film forming, cell loading, electrolyte filling
• Sealing & degassing: side/top sealing, hot pressing, vacuum degassing
• Formation & aging: OCV/IR test, capacity grading
• EOL testing & packing: leak test, X-ray, impedance, full traceability (MES)

How to choose (in 5 checks)

1. Product fit: target dimensions, capacity window, foil/film stack-up, electrolyte type
2. Yield levers: vision alignment, welding stability, sealing temperature window, leak rate
3. Throughput & OEE: changeover time, auto-recipe control, SMED tooling
4. Digital backbone: MES/SCADA hooks, barcode/laser marking, full genealogy
5. Service & spares: onsite response, spare-parts lead time, language & documentation

FAQs

Should I buy a full line from one vendor or mix specialists?

If you’re pre-GWh, a single integrator simplifies ramp. At GWh scale, many teams mix: a turnkey integrator plus specialist modules (e.g., laser welding, formation/aging).

Where do most yields break?

Alignment during stacking, tab welding quality, and sealing leak rate. Prioritize vision systems, stable welding optics, and a tight sealing temperature window.

How can I de-risk my choice?

Run sample trials on your electrodes/film at the vendor’s site, demand video evidence and data, and include the FAT/SAT checklists above in the contract.

Takeaway

Use the quick-compare table to shortlist 2–3 suppliers that match your scale and bottlenecks. For sealing-driven yield issues, consider a focused sealing specialist like XHS Machine; for full GWh ramps, look at whole-line integrators such as Lyric Robot or Wuxi LEAD. Lock requirements with the RFQ block, then validate yield with sample trials before you sign.
