Main Process Flow Of Glass Bottle

The glass bottle production process mainly includes: ① raw material preprocessing. Crushing the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.), drying the wet raw materials, and removing iron from the iron-containing raw materials to ensure the quality of the glass. ②Preparation of ingredients. ③ Melting. The glass batch is heated at a high temperature (1550~1600 degrees) in a pool kiln or pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements. ④Molding. Put the liquid glass into the mold to make glass products of the required shape, such as flat plates, various utensils, etc. ⑤ heat treatment. Through annealing, quenching and other processes, the stress, phase separation or crystallization inside the glass is eliminated or generated, and the structural state of the glass is changed.
