What is the manufacturing process for glass bottles?Just read this article and you will understand!

Glass bottle manufacturing process is simple, free and changeable shape, hardness, heat resistance, clean, easy to clean, and can be repeatedly used and other characteristics.First of all, we must design, determine and manufacture the mold (title: the mother of industry). The raw material of the glass bottle is quartz sand as the main raw material, and other auxiliary materials are dissolved into liquid at high temperature. Then the fine oil bottle is injected into the mold, cooling, cutting and tempering, and the glass bottle is formed.Coloured glass bottles generally have rigid marks, which are also made of mold shapes.The molding of glass bottles can be divided into manual blowing, mechanical blowing and extrusion molding according to the production methods.

(1) raw material pre-processing.Glass bottle China’s traditional beverage packaging container, glass is also a very historical packaging material.In the case of many kinds of packaging materials flooding into the market, glass container still occupies an important position in beverage packaging, which is inseparable with its packaging characteristics that can not be replaced by other packaging materials.The massive raw materials (quartz sand (nature: silicate mineral), soda, limestone, feldspar, etc.) are crushed to make the wet raw materials dry, and the iron-containing raw materials are removed to ensure the quality of glass.

② preparation of complex materials.


(3) melted.The glass mix material is heated at high temperature (1550~1600 degrees) in the tank kiln or furnace to form the liquid glass with uniform, no bubble and in line with the molding requirements.

(4) shape.Put liquid glass into mold (title: mother of industry) to make the required shape of glass products, such as plate, various utensils (ware), etc.

⑤ Heat treatment.To remove or produce stress, phase separation or crystallization within glass and to change the structural state of glass by processes such as annealing and quenching.
