Prior to inspection, they are usually subjected to a cold-end surface coating process that reduces the temperature of the glass container to around 100°C, otherwise the glass scratches easily.
After leaving the cold end of the annealing furnace, to ensure product quality, we use Led Beam Technology (Led Inspection), Camara Inspection Machines, and Integrated Inspection Machines to detect faults not visible to the naked eye. These include, but are not limited to: sealing surface inspection, dimensional analysis, wall thickness inspection, breakage detection, side bottom scanning, and wall scanning. Any bottles that do not meet the standards will be automatically rejected and these rejected bottles will be re-melted and reused as raw material. Automatic inspection will ensure consistent quality for our customers.
