EV power-electronics housings need more than a casting price. Buyers should define thermal surfaces, sealing grooves, grounding points, coolant paths, CNC datums, coating requirements, cleanliness, and inspection records before comparing suppliers.
RFQ checklist
- •2D drawing and STEP model
- •thermal interface flatness and finish
- •coolant path or sealed-cavity requirements
- •O-ring grooves and sealing faces
- •grounding and EMI-related features
- •machining datums and CMM scope
- •finish, coating, masking, and cleanliness
- •leak-test, material, and traceability records
- •annual volume, samples, and launch timing
