You should be familiar with the double-layer glass. It is a more common and frequently used cup product in our lives. Do you know the forming principle of double-layer glass? Next, let’s understand the principle of double-layer glass blow molding:
1. Manually blown double-layer glass
Manual blowing is a more complicated process. First, you need to dip one end of a copper or iron blow tube to take the glass melt. You need to blow on the other end of the blow tube to blow into the shape we need, and then use scissors to reduce it. Up. In the process of manually blowing the double-layer glass, the hand of the operator is to continuously rotate the blowing tube to ensure that the glass solution will not be lost. On the other hand, it is the process of using the viscosity of the glass to shape it into the shape we need. In this way, the double-layer glass that is blown out can be complete in order to coordinate and cooperate with each other. It should be understood that the size and thickness of the double-layer glass are all determined by the amount of air blown.
2. Molded blow molding
First use copper or iron to make a hollow model, then use a blow tube to dip the glass melt, put the glass solution into the mold and start blowing until the glass solution is completely filled with the inner wall of the model and then remove the mold. In this way, double-layer glass cups of various shapes can be produced, which adds artistry to the shape of the cup body.
Now when people choose a double-layer glass, they not only have requirements for its function but also for its appearance, so we can meet the needs of the public by choosing a reasonable blowing method.
