Frequently Asked Questions (FAQ)
Q: What cylindrical cell sizes are compatible with this production line?
Our production line is highly versatile and supports industry-standard cylindrical lithium-ion cells, including 18650, 21700, 26650, and 32700 sizes. Quick-changeover tooling can be integrated to handle multiple cell types on the same line.
Q: Can the line handle both manual and fully automated processes?
Yes, we offer tailored configurations ranging from semi-automated lines (ideal for lower volumes or flexible configurations) to fully automated turnkey systems designed for high-capacity, continuous industrial manufacturing.
Q: What welding technologies are utilized in the assembly process?
Depending on your technical requirements and budget, we integrate high-precision resistance spot welding or advanced fiber laser welding systems to ensure robust and low-resistance tab connections.
Q: How does the production line ensure quality control and safety?
Quality control is integrated at every stage, featuring automated cell sorting (voltage and internal resistance checking), CCD weld inspections, BMS functional testing, and comprehensive end-of-line (EOL) charge/discharge aging tests.
Q: What is the typical lead time for a customized PACK production line?
Lead times vary depending on the level of automation and customization required. Generally, custom turnkey lines take between 12 to 20 weeks from initial design approval and engineering to factory acceptance testing (FAT).
