Glass Bottle Manufacturing

Glass bottle manufacturing involves transforming raw materials like sand, soda ash, and limestone into a molten glass, which is then shaped into bottles through a process called forming or molding. The molten glass is heated to about 1,700°C, then rapidly cooled and shaped using molds, either by blowing air into it (blow molding) or pouring it into molds (press and blow). After shaping, the bottles are gradually cooled in an annealing oven to prevent stress. Finally, they are inspected and cleaned before packaging. This process ensures durable, uniform bottles suitable for storing beverages, chemicals, or other liquids.
