AI Technical Summary
The existing manufacturing process for round, explosion-proof aluminum casings for new energy vehicles suffers from problems such as weak welds, high production costs, or coarse grains, resulting in insufficient battery safety and production efficiency.
The process employs cold extrusion molding, and by setting explosion-proof grooves on the punch and die, combined with shot blasting to increase lubrication adhesion, and using hard alloy materials and a flower disc feeding mechanism, it achieves seamless one-piece molding and explosion-proof function, thereby improving the density and thermal stability of the aluminum shell.
It improves battery safety and lifespan, reduces production costs, enhances material utilization and battery heat dissipation performance, prevents battery explosions, and increases production efficiency.
