1.Raw material preparation: Select appropriate glass raw materials, such as quartz sand, soda ash, limestone, etc., and carry out precise proportioning and mixing.
2.Melting: Put the mixed raw materials into a high-temperature furnace and heat them to a molten state to form molten glass.
3.Shaping: The glass liquid can be formed into the preliminary shape of the water bottle through blowing, pressing and other methods. During blowing, workers dip a blowpipe into molten glass and shape it through blowing air and molds; during pressing, the molten glass is poured into molds and pressed into shape.
4.Annealing: The formed glass water bottle enters the annealing furnace and slowly cools down to eliminate internal stress and enhance its strength and stability.
5.Cooling: After annealing, cool to room temperature in a suitable environment.
Inspection: Conduct quality inspection on the finished glass water bottles, including inspection of appearance defects, dimensional accuracy, sealing, etc.
6.Packaging: Qualified products are packaged for transportation and sale.
