-Annealing during the manufacturing process of glass bottles
Regardless of the process, after the blown glass container is formed, it is usually treated with a surface coating,
When they are still very hot, in order to make the bottles and cans more scratch resistant, this is called hot end surface treatment, and then the glass bottles are taken to the annealing furnace, where their temperature recovers to about 815 ° C, and then gradually decreases to below 480 ° C. This will take approximately 2 hours. This reheating and slow cooling eliminates the pressure in the container. It will enhance the robustness of naturally formed glass containers. Otherwise, the glass is easily broken.
5- Glass bottle quality inspection
Before inspection, they usually undergo surface coating treatment on the cold end to reduce the temperature of the glass container to around 100 ° C, otherwise the glass is easily scratched.
After leaving the cold treatment end of the annealing furnace, in order to ensure product quality, we use Led beam technology (Led detection), Camara detection machine, and comprehensive detection machine to detect faults that cannot be seen by the naked eye. These include, but are not limited to: sealing surface inspection, dimensional analysis, wall thickness inspection, damage detection, edge and bottom scanning, and wall scanning. Any bottles that do not meet the standards will be automatically removed, and these removed bottles will be remelted and reused as raw materials. Automatic detection will ensure stable quality for our customers.
6- Glass bottle packaging
The packaging method of glass bottles will depend on customer requirements. Usually, we use the following two methods for packaging.
Standard Tray Pack and Case Pack
