Buyers should prioritize Production Capacity (PPM - Pieces Per Minute) to ensure it meets their output targets. Key technical components include Automatic COS (Cast-on-Strap) machines, High-precision Heat Sealing units, and Automatic Leak Testing modules. Ensure the machine supports PLC control systems (e.g., Siemens or Mitsubishi) for stable operation and easy troubleshooting. Additionally, verify the compatibility with different battery sizes (e.g., 12V7Ah to 12V200Ah) to ensure production flexibility.
