Direct answer
Define the defect population and required detection rate first, then select technology and design reject handling and traceability around it.
What this domain covers
- Defects reach customers or trigger recalls
- End-of-line manual inspection is the quality control
- Regulatory or customer audits demand documented inspection
- Rework volume is significant and discovered late
- No data exists on defect type frequency
Solution approaches
Vision inspection
Presence, dimension, print and surface verification.
Weight and fill control
Checkweighing with feedback to filling control.
Contamination detection
Metal detection, X-ray for foreign body and fill integrity.
Functional test stations
Leak, electrical, pressure or performance testing inline.
Engineering and project considerations
- False-reject rate carries real cost — specify both detection and false-reject limits
- Reject handling, containment and reconciliation logic must be designed, not improvised
- Validation protocol and periodic verification routine
- Lighting, fixturing and product presentation dominate vision reliability
- Data retention aligned with traceability obligations
What to prepare before engaging engineering companies
- Defect Pareto with frequency and escape consequence
- Required detection rate and acceptable false-reject rate
- Line speed and presentation conditions
- Regulatory or customer specification references
What to measure
Frequently asked questions
100% inspection or sampling?
100% inline inspection where escape consequence is high or regulation requires it; statistical sampling where the process is capable and consequences are contained.
