Because the content of the answer is limited, here is only a brief description of the production process of flat glasses. You can also go to official website to learn more about our related articles. For example, the manufacturing process of flat glass is described in more detail, and other articles such as the introduction of acetate fiber materials can also be referred to. In fact, to complete a perfect pair of flat glasses, the process is much more than here. According to statistics, there are at least 100 to 200 processes. I hope it helps you.
