The production process of glass bottles mainly includes the following steps:
Raw material pre-processing: Crush block shaped raw materials (such as quartz sand, soda ash, limestone, feldspar, etc.) to dry moist raw materials, and remove iron from iron containing raw materials to ensure glass quality.
Batch preparation: Mix the crushed raw materials in proportion to form a glass batch.
Melting: At high temperatures (1550-1600 degrees), heat the batch in a tank or furnace to form a uniform, bubble free liquid glass.
Forming: Put liquid glass into a mold and use methods such as manual blowing, mechanical blowing, or extrusion to produce the desired shape of glass products.
Heat treatment: By annealing, quenching and other processes, the stress, phase separation or crystallization inside the glass are cleaned or generated, as well as the structural state of the glass is changed.
Annealing: In order to eliminate thermal stress in glass, it is necessary to perform annealing treatment on glass products.
In addition, some factories also use recycled waste glass bottles as raw materials, which are crushed, mixed, melted, and then molded into new glass bottles. Throughout the entire production process, the fully automated assembly line can produce hundreds of glass bottles per minute.
When improving the weight, production and molding rate, as well as personalization and flexibility of glass bottle and can products, the product quality of glass bottle and can products is a very important factor of concern. When improving the production and molding process control of glass bottle and can products, the product quality of glass bottle and can products must also be a very important factor of concern. No matter what changes are made to the molding process, the product quality and performance of glass bottle and can products need to remain unchanged, which is very important.
From the perspective of controlling the molding process and product quality of glass bottle and can products, it is crucial for glass to be evenly distributed throughout the entire bottle and can product. In this way, glass bottle products can have sufficient wall thickness to withstand stress contact from glass forming equipment. Of course, the wall thickness of glass bottle and can products does not need to be too thick, otherwise it will cause excessive consumption of raw materials, energy consumption and use, excessive waste discharge, and other consequences, thereby increasing the cost of glass bottle and can products.
