Frequently Asked Questions
Q: How do you prevent sidewall thinning and wrinkling during deep drawing of tall Prismatic Cell Aluminum Shell?
A: We use multi-station progressive dies paired with precise blank holder force control and specialized synthetic lubricants. Finite element analysis (FEA) during tool design allows us to optimize draw ratios and inter-stage annealing, maintaining wall thickness within ±0.02mm.
Q: What surface preparation is applied to ensure defect-free laser welding with the top cover?
A: Shells undergo multi-stage ultrasonic degreasing, acid etching, and deionized water rinsing to remove all drawing oils and oxide films. This process yields a clean surface state that eliminates porosity and cracking during high-speed laser welding.
Q: Can you develop custom tooling for non-standard cell dimensions or specific OEM designs?
A: Yes. Our in-house tool design and precision machining center (utilizing WAIDA optical profile grinding and slow-wire EDM) manufactures custom dies. We convert STEP files into functional prototypes and PPAP Level 3 production within short lead times.
