Start with the application
A useful supplier review begins with the part, equipment model, material and working condition rather than price alone.
Review manufacturing fit
Confirm that the factory can support the required casting process, heat treatment, machining range and inspection method.
Ask for verifiable evidence
- Material and hardness records
- Fit-critical dimensional inspection
- Traceable drawing revision
- Packing and shipment identification
Plan for repeat orders
The qualification process should define how samples, revisions, inspection records and future repeat orders will be controlled.
