Aluminium Die Casting
for Electric Vehicles
Electric drivetrains move the challenge from combustion heat to electrical heat and weight. Aluminium die castings carry that heat away while keeping housings light and rigid.
Why EV components suit aluminium die casting
Motor and inverter housings must conduct heat away from windings and power electronics. Die cast aluminium alloys combine good thermal conductivity with the ability to cast integral cooling channels and fins, so one casting acts as housing, mount and heat sink.
Every kilogram saved extends range, which is why EV makers replace steel and multi-part assemblies with thin-walled aluminium castings. Battery and electronics enclosures also need sealing faces that stay flat and leak-tight.
Applications
Typical electric vehicles components we die cast
Rotor end-rings
Cast for consistent electrical and mechanical properties.
Inverter and controller housings
Finned housings acting as heat sinks.
Battery enclosure sub-assemblies
Flat, sealable faces for IP-rated enclosures.
Charger housings
Thin-walled covers with mounting bosses.
Quality requirements
EV-specific requirements
- Leak tightness
- Cooling jackets and enclosures are leak tested to an agreed pressure and medium.
- Thermal performance
- Alloy selection and wall design for heat transfer.
- Thin walls
- High-velocity HPDC fill for thin, light sections.
- Flatness of sealing faces
- Machined and verified for gasket and O-ring sealing.

FAQ
Electric Vehicles castings — FAQ
Which alloy is best for EV motor housings?
AlSi10Mg is often chosen for better ductility and thermal conductivity; A380 and ADC12 are used where castability is the priority. We recommend a grade from your requirements.
Can you cast integrated cooling channels?
Simple cooling jackets can be cast using cores and slides in the die; complex internal channels may need a different design. Send the model for a feasibility review.
