Introduction
The sealing die is essential for assembling button batteries, ensuring components like the anode, cathode, and electrolyte are securely enclosed. It enhances battery safety and reliability by protecting internal materials from external factors.
Application
Functioning as a precise mold, the sealing die compresses and seals button battery components with high pressure and temperature resistance. Made from durable materials like hardened steel, it ensures consistent, high-quality assembly, crucial for maintaining battery performance and safety in electronic devices.
