Before inspection, they are usually treated with a cold end surface coating that reduces the temperature of the glass container to about 100°C, otherwise the glass is easily scratched.
After leaving the cold end of the annealing furnace, we use Led beam technology (Led inspection), Camara inspection machines, and integrated inspection machines to detect faults that are not visible to the naked eye in order to ensure product quality. These include, but are not limited to: seal face inspection, dimensional analysis, wall thickness inspection, breakage detection, edge bottom scanning, and wall scanning. Any non-compliant bottles will be automatically rejected and these rejected bottles will be re-melted and re-used as raw material. Automated inspection will ensure consistent quality for our customers.
