   Glass bottle production process
       First, design and determine the mold. The glass raw material uses quartz sand as the main raw material, plus other auxiliary materials that dissolve into a liquid at high temperature. Then it is injected into the mold, cooled, cut and tempered to form a glass bottle.
      Glass bottles usually have a rigid logo, and the logo is also made of the shape of a mold.
      Glass bottle molding can be divided into three types: manual blowing, mechanical blowing and extrusion molding.
      Glass bottles can be divided into the following types according to their composition:
      One is soda glass, the other is lead glass, and the other is borosilicate glass.
      The main raw materials of glass bottles:
      The main raw materials of glass bottles are natural ore, quartz stone, caustic soda, limestone and so on.
      Glass bottles are highly transparent and resistant to corrosion, and will not change material properties in contact with most chemicals. The manufacturing process is simple, the shape is free and changeable, the hardness is large, heat-resistant, clean, easy to clean, and it can be used repeatedly.
      Glass bottle application:
      As a packaging material, glass bottles are mainly used in food, oil, alcohol, beverages, condiments, cosmetics, and liquid chemical products. However, glass bottles also have their disadvantages, such as heavy weight, high transportation and storage costs, and resistance to impact.
