EV Battery Case (Tray)
Large-format structural aluminum die casting. Engineered for impact resistance, high payload capacity, and lightweight vehicle architecture.
- Alloys: AlSi10MnMg, A356 (High Yield Strength & Ductility)
- Core Process: Large-Tonnage HPDC (Up to 4,500T)
- Validation: X-Ray Flaw Detection & Large-Format CMM Verified
Manufacturing Challenges We Control
Producing large battery trays requires strict management of mechanical properties, thermal warpage, and chassis alignment.
Crash Resistance & Ductility
Structural trays must absorb impact without shattering. We utilize specialized ductile alloys and controlled heat treatments (T4/T6) to meet strict yield strength and elongation requirements.
Large-Format Warpage
Casting extensive surface areas inherently risks thermal distortion. We manage mold temperatures dynamically and use specialized CNC fixtures to maintain strict flatness tolerances.
Chassis Alignment
Mounting points must align flawlessly with the vehicle frame. Our large-scale Zeiss CMM equipment verifies critical coordinate dimensions, ensuring consistent drop-in assembly at your facility.
