The production process of glass bottles is a delicate and multi-step process, which mainly includes the following key steps:

1. Raw material pre-processing


Iron removal: remove iron from iron-containing raw materials to reduce the impact of iron on the color of glass and ensure the quality of glass.
2. Preparation of batch materials

3. Melting
High temperature heating: send the glass batch material into a pool kiln or pool furnace for high temperature (usually 1550~1600 degrees) heating.
Melting and stirring: the raw materials are gradually melted and mixed into molten glass at high temperature. This process takes several hours, and multiple stirring is required during the period to ensure that the raw materials are fully integrated to form a uniform, bubble-free liquid glass.
4. Molding


5. Heat treatment


6. Post-processing


7. Quality inspection and packaging

In summary, the production process of glass bottles includes raw material pre-processing, batch material preparation, melting, molding, heat treatment, post-processing, quality inspection and packaging. Each link requires delicate operation and strict quality control to ensure that the produced glass bottles have excellent quality and performance.
