Glass wine bottle production process

As the most common container for alcohol, glass wine bottles can be seen everywhere in life. Do you know that an ordinary glass wine bottle needs to go through many processes from raw materials to finished products, and many people's hard work can take shape. Today I will give you a simple popularization Take a look at how glass wine bottles are created from scratch.
Glass bottle production process mainly includes:
① Raw material preprocessing. 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.
② Batch material preparation.
③ Melting. The glass batch material is heated at a high temperature (1550~1600 degrees) in a pool kiln or a pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.
④ Forming. 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, eliminate or generate stress, phase separation or crystallization inside the glass, and change the structural state of the glass.
