Direct answer
Compatibility must be proven across product contact, storage, temperature, pressure, sealing, labelling, handling and the normal range of supplier variation. For cap feeding and sorting, confirm the result with representative product and packaging before altering several variables at once.
Likely causes
- Product attacks seals, hoses, liners or adhesives in the cap feeding and sorting process.
- Temperature or storage changes pack performance in the cap feeding and sorting process.
- The pack is dimensionally compatible but mechanically unstable in the cap feeding and sorting process.
- Trials do not represent production variation in the cap feeding and sorting process.
What should be checked first?
- Obtain current technical and safety data
- List every product-contact material
- Test minimum and maximum temperatures
- Check sealing, torque, label and transport behaviour
- Use more than one material batch
- Run the actual production process
- Document approved combinations and limits
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.

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

Capping and closuresHow can I increase cap feeding and sorting 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.

Capping and closuresWhy does cap feeding and sorting 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.
