Glass bottle production process - Expertise in manufacturing

Source:This site The timing of the press release:2023 - 3 Visitors:156


Glass bottle production process mainly includes: raw material preprocessing, compound preparation, melting, forming, heat treatment of these steps. Raw material preprocessing is to crush massive raw materials (quartz sand, soda ash, limestone, feldspar, etc.), dry wet raw materials, iron containing raw materials for iron removal treatment, in order to ensure the quality of glass. The preparation and melting of the complex is that the glass complex is heated at a high temperature of 1550~1600 degrees in the pool kiln or the pool furnace to form a uniform, no bubbles, and meet the molding requirements of the liquid glass forming. Molding is the liquid glass into the mold to make the required shape of glass products, such as plate, a variety of utensils and other heat treatment. Heat treatment is to eliminate or produce the stress, phase separation or crystallization inside the glass, and change the structural state of the glass through annealing, quenching and other processes.


In addition, in order to increase the strength of some glass products, can be rigid treatment. Including: physical hardening (quenching), used for thicker glasses, tabletop glass, car windshield, etc. And chemical rigid (ion exchange), used for watch glass, aviation glass, etc. The principle of hardening is to create compressive stress on the surface layer of glass to increase its strength.


Sometimes, according to the different needs of customers, glass bottle manufacturers also need to draw a variety of exquisite patterns on the surface of glass bottles, which is what we often see on glass bottles. Therefore, not only the production process needs to have superb technology, but also have creative design ability.
