Glass Bottle Production Process

The glass bottle production process mainly includes: ① Raw material preprocessing. Block raw materials (quartz sand, soda ash, limestone, feldspar, etc.)
Crush, dry wet raw materials, and remove iron from iron-containing raw materials to ensure glass quality. ② Batch material preparation. ③ melting
system. The glass batch materials are heated at high temperature (1550~1600 degrees) in the pool kiln or pool furnace to make them uniform and free of bubbles.
And cut into the liquid glass required by the molding. ④ Forming. Put the liquid glass into the mold to make a glass product of the desired shape,
Plates, various utensils, etc. ⑤ heat treatment. After annealing, quenching and other processes, the stress and phase separation inside the glass are removed or generated
Or crystallize, and change the structural state of the glass.
Glass bottles generally have rigid marks, and the marks are also made of mold shapes. The molding of glass bottles can be divided into artificial blowing according to the production method
System, mechanical blowing and extrusion molding three.
