Finished Product Evaluation
Preforms
- Conduct tests on preforms to determine weight and length conform to specification
- Test for ovality, IV and AA
- Inspect preforms for defects such as cracks, holes or perforations, damaged thread finish, broken/cracked neck flange, presence of foreign materials, haziness and other defects
- Inspect preforms for defects such as nicks, warping, or dimensional inaccuracies that could affectblow-moulding and sealing.
- Perform Sensory Analysis for foreign odours and ensure colour conforms to standard
Closures
- Measure preforms to determine height, weight, external diameter
- Perform secure seal testing
- Perform Sensory Analysis for foreign odours and ensure colour conforms to standard
- Inspect preforms to check for ovality, integrity of the ID safety band, pilfer band and inner seal plug
- Where closures are branded, ensure that the branding is legible, clear and centred
- Inspect for scratched or blurred graphics
- Inspect closures to ensure there are no cracked or deformed shells and other defects
- Test closures for ovality, liner integrity, seal strength, and application torque to prevent leaks or tampering.
Carbon Dioxide
- Perform hourly analysis of purity and ensure compliance to SANS 532 and ISBT standards
- Perform analysis for impurities
- Monitor CO2 process efficiency
- Perform sensory analysis and escalate any off odours and any foreign bodies to Operations
- In process checks on operational efficiencies of the boiler and burner
Document Control and Record Keeping
- Ensure the accurate and complete compilation of all records and control of documentation
Verification
- Verify that preforms, closures, and related materials conform to specifications, recording batch numbers for traceability and reporting any non-conformances to supervisors.
Process Control
- Ensure that the manufacturing process remains within specification
- Any deviations from the manufacturing process is investigated for the root cause and the appropria
