Process Flow Of Glass Bottles

The production process of glass bottles mainly includes: ① pre processing of raw materials. Crush bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.), dry wet raw materials, and remove iron from iron containing raw materials to ensure glass quality Batch preparation. ③ Melting. The glass batch is heated at high temperature (1550-1600 degrees) in a tank furnace or furnace to form a uniform, bubble-free liquid glass that meets the molding requirements. ④ forming. Put liquid glass into a mold to make glass products of the required shape, such as flat plates, various utensils, etc Heat treatment. Through annealing, quenching, and other processes, stress, phase separation, or crystallization within the glass can be eliminated or generated, as well as the structural state of the glass can be changed.
