EV traction motor housing
Review bearing-axis alignment, stator fit, cooling interfaces and the leak-test specification.
Aluminum Die Casting
EV & Electric Motor Housings Manufactured to Drawing.
Die-cast and machined aluminum housings for traction motors, industrial motors and integrated e-drive systems — reviewed around bearing alignment, cooling, sealing and production volume.
Drawing Review
EV & Electric Motor Housings — Component Examples
Representative component requirements, not delivered customer projects. Each example highlights details to define for a drawing-based feasibility review.
Machined motor end bell
Define bearing-seat tolerances, shaft clearance, mounting datums and sealing-face finish.
Inverter cooling housing
Specify thermal-pad flatness, coolant compatibility, port geometry and allowable leakage.
Integrated e-axle housing
Review gear and bearing datums, assembly access, joint sealing and machining allowances.
Typical Applications
- ✓EV traction motors
- ✓E-axle and gearbox housings
- ✓Industrial servo motors
- ✓Pump and compressor motors
Materials & Finishes
- ✓ADC12 / A380 for production castability
- ✓A360 where corrosion resistance matters
- ✓Project-specific low-porosity alloys
- ✓Managed powder coat, e-coat and conversion coating

Frequently Asked Questions
Can cooling channels be integrated?
Yes, subject to geometry and process review. The casting, machining and leak-test route is confirmed from the drawing before quotation.
What tolerances can be held on bearing bores?
Critical bores are CNC finished after casting. Achievable tolerance and positional control depend on size, datum structure and inspection access.
