China Glass Bottle Factory Manufacturing Process

There are many glass container factories in China, distributed in Jiangsu, Shandong, Anhui, Guangdong and other provinces.The glass bottle manufacturing process is simple, the shape is free and changeable, the hardness is large, heat-resistant, clean, easy to clean, and can be used repeatedly.
First of all, we must design, determine and manufacture the mold
, The glass bottle raw material uses quartz sand as the main raw material, and other auxiliary materials are melted into liquid at high temperature, and then the liquid is poured into the mold, cooled, cut, and tempered to form a glass bottle. glass bottles generally have a rigid characteristic, which is characteristic of the shape of the mold is made.
According to the manufacturing method, glass bottles can be divided into three types: manual blowing, mechanical blowing and extrusion molding.

①Pre-processing of raw materials. Glass bottle my country's traditional beverage packaging container, glass is also a kind of packaging material with a long history. With many packaging materials pouring into the market, glass containers still occupy an important position in beverage packaging, which is inseparable from its packaging characteristics that other packaging materials cannot replace. The bulk material (quartz sand (Nature: silicate mineral), soda ash, limestone, feldspar, etc.) crushing the moist material is dried, the raw material in addition to iron, so as to ensure the glass quality.

② With materials prepared.

③Melting. The glass batch material is heated at a high temperature (1550~1600 degrees) in a pool furnace or a pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.

④Forming. The liquid glass into a mold to make the desired shape of the glass article, various containers (Ware) and the like.

⑤ Heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of the glass is eliminated or generated, and the structural state of the glass is changed.
