Batch traceability links raw material, production conditions, diameter, test results and shipment. It enables recall, complaint analysis and repeatable improvement. A label alone is not traceability.
What to record
- Raw-material lot.
- Date and machine.
- Process parameters.
- Inspection results.
- Shipment and customer.
Control the chain
Use unique batch numbers, controlled labels and retained samples. Link changes in resin, additive or line setup to the affected output.
Use the data
- Complaint investigation.
- Trend analysis.
- Corrective action.
- Supplier feedback.
| Stage | Record | Purpose |
|---|---|---|
| Input | Lot and certificate | Source control |
| Process | Machine and settings | Repeatability |
| Test | Measured values | Acceptance |
| Shipment | Batch and customer | Recall |
Common engineering mistakes
- No batch code.
- Reusing labels.
- Mixing output.
- Losing samples.
- No corrective action.
Buyer checklist
- Can the batch be identified?
- Are materials linked?
- Are tests recorded?
- Can shipment be traced?
- Is action documented?
