EV Battery-Tray Reinforcement — Roll-Formed 980MPa-Class Steel
980MPa-class steel that cracks in stamping, mass-produced via roll forming + laser welding for a major EV maker's battery trays.
- 01
Challenge
Reinforcement beams inside an EV battery tray must deliver crash-grade strength and range-saving light weight at once. In conventional stamping, 980MPa-class steel suffers hard-to-control springback and cracking, making yield unstable.
- 02
Approach
Roll forming bends the steel gradually, keeping 980MPa-class material stable. Partner factory BRFM pairs in-house-designed roll tooling with an in-line laser-welding line to produce closed-section beams continuously, with 100% in-line dimensional monitoring.
- 03
Outcome
Now in mass production for a major EV maker's battery trays — holding material cost below aluminum extrusion while meeting crash targets. The same section know-how extends to energy-storage (ESS) enclosure frames.
