Direct answer
Inspect the characteristics that define a good pack, use measurable limits and ensure failed packs are identified, rejected and recorded. For cap feeding, confirm the result with representative product and packaging before altering several variables at once.
Likely causes
- The defect is defined subjectively in the cap feeding process.
- Sampling misses short recurring faults in the cap feeding process.
- The inspection cannot identify the right product in the cap feeding process.
- Reject confirmation is absent in the cap feeding process.
What should be checked first?
- Define measurable pass limits
- Choose the inspection point before control is lost
- Test known good and known bad samples
- Confirm product tracking through rejection
- Record rejects by reason
- Challenge sensor and data failure
- Audit retained samples and records
What should you compare before buying?
Compare the operating principle against the actual product, pack range, sustained good output, measurable quality limits, cleaning, changeover and site conditions. Use representative samples and agree what will be demonstrated during testing before delivery and after installation.

Related cap feeding questions
Preparation and feedingWhy is cap feeding production giving inconsistent results?
Variation usually begins with changing product or packaging conditions, unstable presentation, unsuitable settings or wear in the process.

Preparation and feedingHow can I increase cap feeding production speed?
Increase sustained good output by identifying the actual constraint, separating machine cycle time from handling time and removing the first recurring cause of waiting.

Preparation and feedingWhy does cap feeding equipment keep jamming or stopping?
Find the first point where control is lost. A downstream alarm is often only the final symptom of poor feeding, transfer, detection or format control.
