Hot coating process is applied to glass packaging immediately after the forming machines. The purpose of this process is to seal the microfractures in the bottles and to form a primer for the Cold Coating process to be applied after the annealing furnace.
During forming, glass packages are loaded with unwanted stresses that reduce their strength by sudden and uncontrolled cooling. The annealing furnaces are used so that the resulting stresses (pressure) can be removed by controlled cooling (annealing).
Glass packages can be drawn by touching a glass as they travel along the lines. These scratches can affect strength in a negative way. In order to prevent these scratches, a cold coating liquid suitable for water-based food is applied which gives a sliding property to the contact areas on the outer surface of the glass packages.
1- Glass packaging with cold coating liquid is subjected to various controls and tests (visual inspection, gauge control, pressure and impact control) by a sampling method.
2- All of the unshaped products pass through the latest technology for splitting, checking the head, bottom, side surface, crack, mouth seal and narrow neck.
3- By taking samples from products passing through fault splitting machines, the latest visual checks are carried out by both operators and online machines, and after the approval of the quality department, they are sent to the packaging.
Correction of the error is ensured by instantly reporting the detected faults to the forming area. At the same time, defective glass packaging is recycled by thrown back into the furnace in order to feed the furnace again
