Buyers of machined parts usually evaluate suppliers from five key aspects:
- Quality Control System – Whether the supplier has ISO9001 / IATF16949 and can provide inspection reports (FAI, SPC, MSA).
- Communication & Responsiveness – Quick quotation, clear technical feedback, and transparent order tracking.
- Delivery Reliability – Stable lead time, packaging quality, and logistics management.
- Cost Competitiveness – Not just the lowest unit price, but the overall cost (yield rate, rework risk, logistics).
- Technical Capability – Ability to handle complex geometries, multi-axis machining, and material diversity.
