Glass Bottle Production Process And Product Acceptance

Most of the raw materials used to make glass bottles are sand, soda ash, and limestone. Glass shards are added to such mixed substances.
The raw materials and glass fragments continue to melt at high temperatures, at 165 ℃. The furnace operates 24 hours a day, and the mixture of raw materials takes about 24 hours to form molten glass. Molten glass is processed according to the material channel, and then at the end of the channel, the glass flow is cut into blocks based on weight, with precise temperature settings.
There are generally two molding processes available: pressure blowing or blow blowing, which are carried out in IS machines. The material droplets processed by pressure blowing glass bottles are dropped and pressed into a blank mold containing a metal material plunger, where it expects the shape of the mold and is called a billet. So next, move the billet into the final mold, blow it into the mold, and perform the final precise measurement. This process is generally used for wide mouthed glass bottles, but can be used for the production and manufacturing of narrow necked glass bottles.
After cutting well, the material droplets are compressed into the blank mold during blow molding. Compressed air is used to push the droplets into place, which is called a billet. They are then moved to the final mold for blow molding again, forming the inner side of the frame glass bottle. Glass bottles (narrow containers) with different neck thicknesses can be produced using blowing arrangements. After blowing the glass containers into shape, surface spraying treatment is usually carried out. When it is still very hot, in order to make the bottles and cans more scratch resistant, this is called hot end surface treatment. Afterwards, the glass bottles are taken to an annealing furnace where their temperature returns to about 815 ℃ before gradually decreasing to below 480 ℃. This will take about 2 hours. This type of reheating and slow cooling avoids pressure in the container. It will enhance the durability of naturally formed glass containers. Before inspection, they are usually treated with cold end surface spraying to reduce the temperature of the glass container to 100 ℃, 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 equipment, and comprehensive detection equipment to detect faults that are not visible to the naked eye. This includes, but is not limited to: sealing surface inspection, size 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 those removed bottles will be melted and reused as raw materials. Automatic recognition will ensure the quality of the products ordered by our customers.
