Glass bottle production process

- Nov 13, 2018-

Glass is not only clear and clean, but also has high strength and hardness. It is an indispensable material in daily production and daily life. In addition to the common float glass, tempered glass, there are hot melt glass, glassware glass, grinding glass and other varieties with special properties. To understand the glass bottle production process and the characteristics of the jar, read this article.

First, the mould should be designed and manufactured. The glass raw material is made of quartz sand as the main raw material, and other auxiliary materials dissolve into liquid state at high temperature. Then the glass bottle is formed by injection mold, cooling, cutting, tempering and tempering. Glass bottles generally have rigid marks, which are also made of mold shapes. The molding of glass bottle can be divided into three kinds according to making method: manual blowing, mechanical blowing and extrusion forming. Glass bottles can be divided into the following categories according to their composition: first, sodium glass; lead glass; borosilicate glass;

The main raw materials of glass bottles are natural ores, quartzite, caustic soda, limestone and so on. Glass bottles have a high degree of transparency and corrosion resistance, contact with most chemicals will not change the material properties. Its manufacturing process is simple, modelling is free and changeable, hardness is large, heat resistant, clean, easy to clean, and can be used repeatedly. As packaging materials, glass bottles are widely used in food, oil, wine, beverages, condiments, cosmetics and liquid chemical products. But the glass bottle also has its shortcomings, such as heavy weight, transport storage costs, not shock resistance and so on.
