Light inspection is a crucial quality control step at the final stage of plastic bottle production. By using specialized light sources and human visual inspection, we ensure both the appearance and functionality of the bottles meet standards.
Key Areas of Light Inspection
- Appearance Defect Check
We examine the bottle for scratches, black spots, bubbles, deformation, or any other imperfections.
- Neck Integrity Check
We check the bottle neck threads for completeness, ensuring no burrs or damage. We also verify that the sealing surface is smooth to prevent leakage after filling.
- Foreign Object/Impurity Detection
Under strong light, we inspect the bottle to ensure there are no leftover debris, oil stains, or other impurities inside.
This process helps guarantee the quality and safety of your plastic bottles.
