China Aluminum Casting Supplier: 8 RFQ Red Flags

# Evaluate China Casting Suppliers: RFQ Readiness Checklist

Supplier evaluation should test whether a China aluminum casting supplier can turn a drawing package into a controlled production path. Fast replies are helpful, but the better signal is whether the supplier asks the right questions and makes quote assumptions visible.

Use this checklist before approving a supplier for an OEM aluminum casting program.

1. Process-fit review

Ask the supplier to explain why the selected casting route fits your part. The answer should reference wall thickness, alloy, pressure or load requirements, machining stock, surface finish, annual volume, and inspection scope.

2. Drawing and RFQ completeness

Give the supplier a realistic technical package:

• •2D drawing and STEP model
• •annual volume and launch quantity
• •alloy, temper, and mechanical requirements
• •machining and datum requirements
• •leak-test, CMM, X-ray, PPAP, or material certificate needs
• •packaging, destination, and delivery assumptions

Then evaluate whether the supplier identifies missing information instead of guessing.

3. Quality evidence

For engineered castings, ask for the records that match your risk level: material certificates, heat-treatment records, CMM reports, leak-test records, X-ray scope, traceability workflow, corrective-action format, and calibration or inspection-room expectations.

4. Commercial transparency

Ask the supplier to separate tooling, casting, machining, finishing, inspection, packaging, and freight assumptions. This makes quote comparison cleaner and reduces late-stage surprises.

5. Communication quality

Measure clarity, technical detail, next-step ownership, and whether the supplier names open questions. A professional RFQ response should help the buyer make a decision, not just repeat that the part can be made.

Bohua RFQ path

Bohua can review aluminum casting supplier-evaluation packages for process fit, documentation scope, sample approval, and quote assumptions. Send the drawing package through the formal RFQ form when the supplier review is ready.
