Date:Jun 20, 2019

First of all, it is necessary to design and manufacture the mold. The glass raw material is made of quartz sand as the main raw material, and other auxiliary materials are dissolved into a liquid state at a high temperature, and then injected into a 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. The forming of glass bottles can be divided into three types: manual blowing, mechanical blowing and extrusion. Glass bottles can be divided into the following categories according to their composition: one is soda glass, the other is lead glass, and the third is borosilicate glass.


The main raw materials for glass bottles are natural ore, quartz, caustic soda, limestone and the like. Glass bottles are highly transparent and resistant to corrosion and do not change in material properties when 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 has the characteristics of being reusable. Glass bottles are widely used as packaging materials for food, oil, alcohol, beverages, condiments, cosmetics, and liquid chemical products. However, glass bottles also have their shortcomings, such as heavy weight, high transportation and storage costs, and low impact resistance.
