Main raw materials and characteristics of glass bottles

    First, the mold should be designed, determined and manufactured. The glass raw material takes quartz sand as the main raw material, plus other auxiliary materials to melt into liquid at high temperature, and then injected into the mold, cooled, cut and tempered to form a glass bottle. Glazed bottles generally have rigid marks, which are also made of mold shape. According to the manufacturing methods, the molding of glass bottles can be divided into manual blowing, mechanical blowing and extrusion molding. Glass bottles can be divided into the following types according to their composition: one is sodium glass, the other is lead glass, and the third is borosilicate glass.
