How are glass bottles formed by processing

Glass bottle is one of our common daily necessities. Almost everyone of us now cannot live without it. So do you know how glass bottles are formed through refining? Next, our Xuzhou glass bottle manufacturer will share with you the processing process of glass bottle forming.

1. Prepare raw materials for processing glass bottles. According to the mixing ratio, the various raw materials are weighed and mixed uniformly in a mixer. The main raw materials of glass bottles are: quartz sand, limestone, feldspar, soda ash, boric acid and so on.

2. Heat and melt the prepared raw materials. Heat the prepared raw materials to melt them into molten glass. The melting temperature of molten glass is mostly 1300-1600°C. Most of them are heated by flames, and some are heated by electric current, which are called electric melting furnaces.

3. Pour the molten glass into the glass mold, and the glass bottle can be basically shaped. The glass bottle must be formed within a certain temperature range. This is a cooling process. The glass bottle first changes from a viscous liquid state to a plastic state, and then into a brittle solid state.

4. After the glass bottle is formed, it is cooled. Although the forming process of a glass bottle is a heat dissipation process, after it is formed, there will be residual heat, which will reduce the strength of the glass bottle. If it is directly cooled, it is likely to be in the cooling process or later during storage, transportation and use. It breaks by itself, so the cooling of the glass bottle is a gradual process.

Through the above steps, the glass bottle is basically formed. If you have any questions about the glass bottle, please contact us through the official website.
