Q1: What are the main benefits of utilizing extruded aluminum profiles for EV battery shells?

A1: Extruded aluminum profiles offer an exceptional strength-to-weight ratio, which significantly reduces the overall weight of the vehicle to extend driving range. Aluminum also features outstanding thermal conductivity to help dissipate heat from cells quickly, is naturally corrosion-resistant, and allows for complex multi-cavity cross-sections that absorb crash energy effectively.

Q2: How do you guarantee the precise tolerances required for automated battery module insertion?

A2: Automated assembly lines require millimetric accuracy to prevent cell binding or alignment issues. We utilize high-calibrated extrusion technology combined with secondary high-precision CNC machining centers and strict Coordinate Measuring Machine (CMM) inspection protocols to maintain tight tolerances within ±0.1mm on critical internal dimensions.

Q3: Can your battery profiles achieve high electrical insulation standards to ensure pack safety?

A3: Yes, completely. To prevent short circuits and electrical tracking between the cells and the metal outer framing, we can apply specialized high-dielectric powder coatings or thick technical anodizing on the designated interior surfaces, providing excellent insulation and spark resistance.

Q4: What is your process for testing the leak-proof sealability of custom battery shell components?

A4: Securing an airtight and watertight seal (IP67/IP69K standard) is essential for battery protection. We ensure that our extruded profiles have perfectly smooth mating surfaces free from extrusion lines or burrs. Fabricators can seamlessly perform friction stir welding (FSW) or apply custom EPDM gaskets into our precision-machined sealing tracks to achieve a flawless, secure seal.
