HJ Equipment is a professional lithium ion battery manufacturing equipment supplier based in Shenzhen, China. Our cylindrical cell equipment covers every critical stage of a lithium battery making machine line — cell grading, vacuum baking, can sealing, automated assembly, and full PACK assembly — supporting all mainstream cylindrical formats including 18650, 21700, 26650, 32140, 32700 and 4680 tabless cells.
Every machine we ship is engineered for one goal: stable, repeatable battery quality at industrial scale. With more than 500 machines running in 30+ countries, our production systems help cell makers, PACK factories and research institutes reduce labor cost, raise yield and pass the strictest customer audits.
| Equipment | Function in the Production Line | Key Capability |
|---|---|---|
| Cylindrical Cell Grading System | Automatic sorting of cells by capacity, voltage and internal resistance (OCV/IR testing) | High-speed channel testing with automatic binning, MES data upload |
| Cylindrical Cell Baking System | Vacuum baking to remove moisture from electrodes and cells before electrolyte filling | Precision temperature control, uniform vacuum, low dew point integration |
| Cylindrical Cell Sealing Machine | Hermetic can sealing after electrolyte injection to guarantee long cycle life | Servo-controlled sealing force, leak-rate monitoring, zero-defect output |
| Cylindrical Cell Assembly Line | Automated inline transfer linking welding, grooving, inspection and testing stations | Modular design, PLC + HMI control, quick format changeover |
| Cylindrical Cell PACK Assembly | Module and PACK assembly: sorting, laser welding, BMS integration and EOL testing | Flexible for NCM / LFP chemistries, semi-auto to full-auto options |
Each machine can be purchased individually or integrated into a turnkey lithium ion battery manufacturing equipment line. Browse the complete product list above for detailed specifications, or contact our engineers for a tailored configuration.
A cylindrical lithium battery production line typically flows from electrode manufacturing to finished PACK. HJ Equipment machines take responsibility for the stages that decide final battery performance:
From classic 18650 cells for power tools to large-format 32140 LFP cells for energy storage and 4680 tabless cells for next-generation EV platforms, our lithium battery making machines adapt through quick-change tooling and recipe management. One line can serve multiple SKUs, protecting your investment as your product roadmap evolves.
Planning a soft-pack line as well? Explore our pouch cell equipment for lamination, stacking, degassing and formation systems.
Our standard tooling covers 18650, 21700, 26650, 32140, 32700 and 4680 cells. Changing between formats is done through quick-change fixtures and recipe switching, typically within 30 minutes. Custom sizes can be engineered on request.
Yes. We deliver both single machines and complete turnkey lithium ion battery manufacturing equipment solutions, including layout design, machine integration, PLC/MES connectivity, on-site commissioning and operator training.
Standard machines are usually shipped 30–45 days after order confirmation. Complete production lines require 60–90 days depending on configuration. Urgent orders can be scheduled with priority production slots.
Every order includes remote commissioning guidance; on-site installation and training by our engineers is available worldwide. All machines carry a 12-month warranty with lifetime spare-parts support and 24-hour technical response.
Yes. Our equipment supports standard industrial protocols (Modbus, OPC-UA, TCP/IP) and integrates with Siemens or Mitsubishi PLC systems, MES/ERP platforms and existing upstream or downstream equipment.
