How to make double wall glass craft glass cup?

In people's impression, glass is a fragile and transparent material, and it is easy to hurt people because of the sharp fragments, and the safety is not strong. However, with the development of science and technology, people can not only make full use of the natural advantages of glass, but also adjust their performance to make up for its shortcomings. This article will introduce how the glass is manufactured, and specially introduces the production process of double wall glass cup.

1. Double wall glass cup process

The Double wall glass cup is mainly a temperature -preserving and insulation function. At the same time, we can also save the ice cubes. We produce Double wall glass cup ice buckets. The layer of vacuum dual -layer cup is generally manual. The middle layer is not a vacuum at all. There is an air hole at the bottom of the outer layer, so that the gas is excreted during the blowing process to prevent the cup from deforming and bursting. After the production is completed, the pores are sealed. There is a loud noise, and it will fry the glass fragments, which is easy to hurt people. When you buy the Double wall glass products, there will be a sealed hole. The sealing holes of the Double wall glass pot are generally under the pot.

The production is relatively complicated. Generally, 5 to 9 people can produce normally.
