Request a QuoteIn the rapidly evolving electric vehicle (EV) market, the efficiency and safety of battery systems depend heavily on the quality of their enclosures. At Alumcasting, we provide world-class EV battery housing die casting solutions, leveraging over 20 years of expertise in aluminum die casting services to meet the stringent requirements of modern e-mobility.

Our 5,000-ton high-pressure die casting (HPDC) equipment is capable of producing massive, single-piece EV battery trays and structural components.
Why Choose Aluminum Die Casting for EV Battery Trays?
Aluminum is the material of choice for EV battery enclosures due to its exceptional strength-to-weight ratio and thermal conductivity. Our casting process ensures:
- Lightweight Performance Reducing vehicle weight to maximize driving range without compromising structural integrity.
- Complex Geometries Advanced die designs allow for integrated cooling channels and mounting brackets in a single cast.
- EMI Shielding Inherent electromagnetic interference shielding properties protect sensitive battery electronics.
- Precision Tolerances Critical for maintaining the air-tightness and leak-proof standards required for battery safety.
Vertically Integrated Manufacturing Process
Unlike standard casting shops, we offer a vertically integrated process that ensures full traceability and quality control from raw ingot to finished assembly.

From 5000T die casting to 400+ CNC machining centers, we provide a complete one-stop solution for EV components.
