FAQ

Here are some common questions from our customers. If you have other inquiries, please feel free to contact us.
1. What is the purpose of the second sealing process in pouch lithium battery production?
The second sealing process ensures the final airtight seal of the pouch cell after electrolyte injection and formation. It is critical for maintaining battery integrity, preventing leakage, and ensuring long-term performance.
The first sealing typically pre-seals the pouch before electrolyte filling, while the second sealing finalizes the cell. Our second sealing machine is designed for ultra-stable temperature control, higher sealing force, and tighter process integration with upstream and downstream equipment.
Yes. Our second sealing machines support customizable tooling and adjustable parameters to accommodate a wide range of pouch cell formats, including prismatic and irregular designs.
Our equipment delivers sealing temperature control accuracy of ±1°C and uniform pressure distribution, ensuring consistent sealing quality across batches.
Absolutely. The machine is designed with automation interfaces, allowing seamless integration into semi- or fully automated lines with robotic loading, conveyors, and inline quality inspection systems.
Yes. We offer full customization services, including sealing head design, footprint adaptation, and interface modification to match your specific production layout and process flow.
Our machines are compatible with typical pouch materials used in lithium-ion battery production, such as aluminum-laminated film (Al-plastic film), with adjustable sealing parameters for multilayer structures.
Yes, we offer global onsite installation, commissioning, and technical training to ensure your team can operate the machine efficiently and safely.
Lead times vary depending on customization level and order volume. Standard machines typically ship within 8–12 weeks, with installation and commissioning completed in 1–2 weeks.
We provide remote technical support, spare parts supply, software updates, and optional onsite maintenance. Our local service teams and global partners ensure fast response when needed.
