EV Battery Cooling Plate — Full-Cycle High-Conductivity Aluminum
Battery cooling plates made full-cycle — cast rod through extrusion, joining, and leak testing — earning a spot on a top-tier global maker's approved-supplier list.
- 01
Challenge
EV cells are temperature-sensitive; a cooling plate with internal coolant channels needs high thermal conductivity and leak-tight construction. The hard part: internal material quality (porosity and inclusions from casting) turns directly into leak failures.
- 02
Approach
The partner is a full-cycle aluminum plant — casting its own rod, then extruding, machining, joining, and finishing in-house. The material is high-conductivity 3003 series; controlling internal quality from the casting stage secures leak-test yield at the source.
- 03
Outcome
Approved on a top-tier global maker's supplier list, supplying cooling plates and module end plates for EV traction batteries. Recycled aluminum (an 80,000 t/yr operation) also cuts the environmental footprint.
