- Issue: Stress cracks appear as fine cracks that can develop in the bottle due to internal stresses. This often occurs in brittle materials or from uneven cooling during molding.
- Possible Causes:
- Brittle materials.
- Uneven cooling or temperature fluctuations.
- Improper handling or storage.
- Troubleshooting Steps:
- Review material choice and conduct stress resistance tests.
- Inspect the cooling process to ensure even temperatures.
- Investigate any mishandling or improper storage conditions.
- Solutions:
- Switch to more flexible or impact-resistant materials like PETG or polycarbonate.
- Improve cooling procedures to avoid uneven stress.
- Provide better training on handling and storage to reduce stress during transportation.
- Preventive Measures:
- Select materials based on impact and stress resistance tests.
- Regularly optimize mold cooling parameters to ensure consistent material properties.
