Product Application
Extruded aluminum profiles are fundamental to the lightweighting, structural integrity, and performance of New Energy Electric Vehicles (NEVs). Their application spans several critical systems:
This is the most significant application. Battery Enclosure Trays and Cross Members are primarily constructed from complex, multi-void extruded profiles. They provide a rigid, protective structure for battery modules while minimizing weight. Internal Cooling Plate/Channel profiles are also extruded to form the foundational part of the thermal management system.
Aluminum extrusions are key in space frame designs and as reinforcement elements. They are used in Crash Management Systems (front and rear crash boxes, side sill reinforcements), A/B/C Pillar reinforcements, Roof Rails, and Subframe components. Their high strength-to-weight ratio and excellent energy absorption are crucial for safety and efficiency.
Beyond battery cooling, extruded profiles form the main heating/cooling plates for the Power Electronics (e.g., inverter, DC-DC converter) and are often integrated into Motor Housings to manage heat from the e-drive unit.
Applications include Side Impact Door Beams, Bumper Beams, Seat Frame components, and various Cross-car Beams. Their use enhances safety and reduces cabin weight.
Drive Shaft Tubes (for lightweighting) and structural supports for Charge Port housings also utilize specialized extrusions.
Precision is non-negotiable. We supply sheets with superior dimensional consistency, featuring tight thickness tolerances (as low as ±0.1mm) and exceptional flatness. This is crucial for reliable laser welding or FSW (Friction Stir Welding) processes, ensuring leak-proof seams for liquid-cooled systems and maintaining the critical seal that protects sensitive battery cells from moisture and contaminants.
