Automotive & EV Casting Cases
Automotive and EV projects are not judged by one sample photo. Buyers care about repeatable casting, controlled machining, burr control, clean mounting faces, and whether the same part can be supplied again without surprises.
Customer names, drawings, and commercial details are not shown. The case format below is written to show the engineering review points a buyer can compare with their own drawing.

Buyer Pain Points Behind This Type of Part
A sample can hide batch risk
A one-off sample may pass, but repeat orders reveal tooling, burr, machining, and inspection problems quickly.
Functional areas matter more than the outside shape
Bearing seats, sealing faces, and threaded holes decide whether the part can be assembled, not the casting photo alone.
What We Reviewed Before Quotation
- Whether die casting, gravity casting, or sand casting gives the best balance for the part size and quantity.
- Which areas cannot tolerate porosity because they are sealing, bearing, or assembly surfaces.
- How machining allowance should be planned around bearing seats and threaded holes.
- What inspection points should be reported for sample approval and repeat orders.
What to Send for a Similar RFQ
- 2D drawing and 3D model if available, including tolerances for machined areas.
- Material grade, working condition, expected quantity, and whether samples are required first.
- Machining notes for holes, threads, bearing seats, sealing faces, datums, or visible surfaces.
- Inspection documents required by the buyer, such as material report, CMM report, pressure/leakage test, or surface finish notes.
Related Case Notes
If your part has similar concerns, send the drawing first. We will review the casting route, machining areas, inspection needs, and RFQ information before quoting.
