EV Battery Pack Housing

Durable aluminum enclosures for battery modules. Engineered for strict gas-tight sealing, EMI shielding, and reliable integration with structural trays.

Manufacturing Challenges We Control

Protecting sensitive battery cells requires strict management of sealing faces, porosity, and environmental resistance.

Gas-Tight Sealing

Moisture ingress causes catastrophic battery failure. We maintain strict porosity control along mating edges and 5-axis CNC machine the interfaces to support your final IP67/IP68 assembly limits.

FSW & Assembly Compatibility

Modern battery packs are often sealed via Friction Stir Welding (FSW) or strict gasket bolting. Our castings provide the uniform material density and precise flatness required for defect-free joining.

Corrosion Resistance

Exposed to harsh underbody environments, housings must resist salt spray and chemical attack. We apply automotive-grade surface treatments like chromating and e-coating to extend component lifespan.
