We are glass bottles manufacturer in China,this article introduce Glass Bottle Manufacturing Process,glass bottle production line.You will how to make glass bottle ,such as beer bottle ,beverage bottle,etc.How to package glass bottle .You can get a customized glass bottle.
The majority of raw materials used to manufacture glass bottles are sand, soda ash, and limestone.Cullet is added to this mixture. Cullet is broken glass, either scrap from the manufacturing process,or from recycling centers, each ton of glass that is recycled 1300 pounds of sand, 410 pounds of soda ash, and 380 pounds of limestone are saved.This will save cost for manufacturing ,save cost and energy,so customer can get economical price on our products.
The cut gob falls, in blow-and-blow formation, the gob is constrained into the blank mould using compressed air to push the gob into place，named a parison, moved into the final mould where it is blown once more,to frame the inside side of the glass bottles. Glass bottles of varying neck thickness(narrow containers) can be made utilizing blow-and-blow arrangement.
No matter the process, after the blown glass containers are shaped, they are usually treated with a surface coating ，
when they are still hot, to make the bottles and jars more resistant to scratches, this is named hot-end surface treament,then glass bottle are carried into Annealing Lehr, where their temperature is brought back up to roughly 815 °C , then lessened step by step to beneath 480°C. This will take about 2 hours.This reheating and slow cooling eliminates the stress in the containers.Will enhance the solidity of the naturally formed glass containers.Otherswise, the glass would easily break.
Before inspection,they are usually treated with a cold end surface coating ,the temperature of glass containers is reduced to about 100°C.Otherswise, the glass would easily scrach.
After leaving the cold treating end of the Annealing Lehr,in order to ensure product quality.We use Led beam techonogy（Led inspection）,Camara inspection machine,and Comprehensive inspection machine to detect faults which are not seen through the naked eye.These include, but are not limited to: sealing surface inspection, dimensional analysis, wall thickness inspection, damage detection,side base scanning and wall scanning.Any bottles doesn’t meet standard ,then will be automatically rejected ,these rejected bottles will remelted as raw material to reuse.Automatic inspection will ensure our customers stable quality.
Glass bottle Packaging methods will be depends on customers requirements.Usually we use below two methods to pack.
After all the glass bottles manufacturing process, glass bottles can be stored as per the required shape & size and then sent it to the filling factory.
