Manufacturing Process of Glass Bottles

The glass bottle packaging is mainly used for food, oil, wine, beverages, condiments, cosmetics, and liquid chemical products, etc., with a wide range of uses. The following is the detailed content about the glass bottle manufacturing process.

The main raw materials of glass bottles are natural ore, quartz stone, caustic soda, limestone, and so on. The glass bottle container has a high degree of transparency and corrosion resistance, and the material properties will not change 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 can be used repeatedly.

First of all, the mold must be designed, determined, and manufactured. The empty glass bottle material is made of quartz sand as the main raw material, and other auxiliary materials are melted into a liquid state at high temperature, and then injected into the mold, cooled, cut, and tempered to form a glass bottle. Glass bottles generally have a rigid logo, and the logo is also made of a mold shape. According to the manufacturing method, the molding of glass bottles 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 third is borosilicate glass.

Crush the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) to dry the wet raw materials, and remove the iron from the iron-containing raw materials to ensure the quality of the glass.

The glass batch is heated at a high temperature (1550 ~ 1600 degrees) in a pool furnace or a pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.

Put the liquid glass into the mold to make a glass product of the required shape.

Through annealing, quenching, and other processes, the internal stress, phase separation, or crystallization of the glass is cleaned or generated, and the structural state of the glass is changed.
