Quality controlled at every stage
Every Redex bottle moves through a multi-stage quality system. It begins at the forming machine and ends with a final QC inspection; in between, an automatic camera photographs each bottle and checks its external and neck-thread dimensions, air bubbles and visual defects, while light and packaging inspections catch any remaining flaws. Non-conforming bottles are separated, and every defect type has its own AQL (Acceptable Quality Level) limit.
Quality tests we perform
Beyond in-line inspection, we carry out laboratory product tests to industry, national and relevant international standards:
- Internal surface hydrolytic resistance test
- Thermal shock test
- Glass grain (particle) hydrolytic resistance test
- Stress (annealing) test
- Heavy metal release test
