When buyers evaluate an Aluminum Die Casting Factory, they should look beyond price and general promises. The factory should show production capacity, tooling support, CNC machining resources, inspection evidence and export packing control. These factors decide whether the supplier can support repeat OEM projects.
Machine tonnage, mold maintenance, operator experience and secondary processing all affect delivery stability. A simple cover plate and a complex machined housing require different levels of tooling review and process control.
| Audit area | What to confirm | Evidence |
|---|---|---|
| Die casting workshop | Machine capacity and production layout | Factory photos or visit |
| Tooling support | DFM, mold maintenance and sample correction | Tooling review records |
| CNC machining | Precision features and fixture control | Machining equipment and sample reports |
| Inspection | Dimensional and functional evidence | FAI, gauges, CMM or fixture reports |
| Packing | Protection for finished parts | Packing photos and export labels |
A useful factory audit asks for marked reports, thread gauge checks, flatness records, coating samples and packing evidence. These documents show whether the factory can repeat good parts, not just make one acceptable sample.
Custom Aluminum Die Casting often needs DFM discussion before mold release. Wall thickness, draft, gate position, ejector marks and machining allowance should be reviewed early. A factory with tooling support can usually reduce sample correction time.
| Checklist item | Reason | Suggested action |
|---|---|---|
| Part examples | Shows similar experience | Review housings, brackets and covers |
| Inspection reports | Shows quality discipline | Request marked FAI samples |
| Machining capability | Controls precision features | Check CNC and fixture planning |
| Surface finish control | Controls visible and functional areas | Review coating and masking samples |
| Communication process | Reduces RFQ mistakes | Confirm drawing review method |
