- Issue: Cracking or fractures in the bottle body or cap can occur during handling, shipping, or filling. These cracks may appear along the body or neck, weakening the bottle and making it unusable.
- Possible Causes:
- Incorrect material selection.
- Insufficient thickness or inadequate molding.
- Exposure to temperature extremes.
- Improper handling during production or shipping.
- Troubleshooting Steps:
- Inspect the material used for brittleness and perform impact tests.
- Check the molding process for uniform cooling and stress.
- Examine cooling rates to ensure even temperature distribution.
- Solutions:
- Use more impact-resistant materials such as PET or HDPE.
- Review and optimize molding conditions, including temperature and pressure.
- Ensure a proper cooling rate to avoid uneven stress buildup.
- Preventive Measures:
- Regularly monitor material properties and mold conditions.
- Implement cooling process optimization and impact resistance testing for materials.
