Pipe Insert Die-casting — Smarter Battery Cooling.
NEDEC's aluminum pipe insert die-casting eliminates the limitations of salt core and steel/copper pipe methods, delivering superior cooling efficiency, simpler production, and full recyclability.
Old Methods vs NEDEC Solution
Salt Core (residue) / Steel·Copper Pipe (ESG non-compliant)
Full Aluminum Pipe — no residue, fully recyclable
Salt Core: complex geometry difficult
Free routing — any geometry achievable
Steel/Copper: mismatch with base material
Aluminum: same material — minimal thermal resistance
Mixed metals — hard to separate — ESG risk
Single aluminum — easy scrap — full ESG compliance
Salt dissolving/removal steps required
Pipe insert + direct die-casting — simplified process
Pipe deformation risk under pressure
Optimized design for BEV high-pressure conditions

Improved Cooling Efficiency
Direct aluminum-to-aluminum thermal contact — no interface resistance. Cooling performance maximized.
Simplified Production
Eliminates salt dissolving and removal steps. Fewer process steps = lower cost and shorter lead time.
ESG Compliant & Recyclable
100% aluminum construction — easy to scrap, recycle, and report under ESG frameworks.
