Quality Control Based on Inspection and Traceability
For industrial washer buyers, quality must be supported by material checks, process inspection, calibrated equipment and batch records.
Quality Control Flow
From incoming material to batch traceability — with anomaly stop-and-recheck at every inspection gate.
1. IQCMaterial cert + heat no.
2. First ArticleCheck before batch run
3. IPQCPatrol: size + HV
4. FQCSize, HV, appearance
5. TraceabilityBack to heat lot + record
Anomaly StopRe-check on deviation at any inspection gate
Documents on order: mill cert · inspection report · calibration · CoC
Inspection Workflow
Each stage gives buyers a clear inspection point from material receiving to shipment release.
| Stage | What We Check |
|---|---|
| IQC - Incoming Inspection | Verify material certificates, heat numbers and incoming specifications. |
| First Article Inspection | Check first pieces before batch production starts. |
| IPQC - In-Process Patrol | Sample key dimensions and hardness during production. |
| Anomaly Response | Stop and re-check when die wear, clearance deviation or dimensional issues are found. |
| FQC - Final Inspection | Final sampling for dimensions, hardness and appearance. |
| Batch Traceability | Trace finished parts back to material, press batch, heat treatment lot and inspection record. |
Inspection Equipment
Equipment and calibration records support dimensional and hardness checks.
