Conclusions
An innovative CCIT method for blister type containers has been presented. The adoption of this method ensures:
the detection of containers that are defective from the integrity point of view
the non-destructive nature.
A further advantage, that this methods provides, is the determination of the location and nature of the defect. This aspect is fundamental for carrying out suitable troubleshooting actions, tailored to the exact reason of the problem (failure of the forming machine, faulty material, incorrect manual operation).
The case study, developed by an automatic machine employing the CCIT method described, provided a quantitative characterization of the performances and sensitivity of the measurement process. Such performances, have been determined by using a large set of containers made microscopically and macroscopically defective. The results obtained, highlighted a significant system sensitivity, a moderate time for detecting defects of various sizes and a high level of reliability and performance of the process.
