Double Wall Glass Cup from China is a widely used cup in our daily life. It is not only safe and healthy, but also can be used to drink a variety of different drinks. So how much do you know about its production process? Its production is mainly divided into two types: manual blowing and machine pressing according to the production method.

1. Manual blowing
The original method should be to manually blow the glass, use a stainless steel hollow tube to pick an appropriate amount of high-temperature molten glass water, blow it into a spherical shape like blowing a balloon, and then put it into the prepared mold and continue to blow it into the same shape. The mold fits the shape of the mold, then open the mold, use a clip to clamp the cup into the annealing kiln to remove the stress of the glass, and then cut, edge, install (foot or handle), and polish to get the finished double layer. glass.
The principle of machine blowing glass is the same as that of manual work, except that it is blown by a human blower into a bubble blower.
2. Machine pressing
The machine for pressing the Double Wall Glass Cup from China is like a revolver. The molds are fixed on the turntable one by one. There are usually 8 or 10 molds in a turn of the turntable. There is a punch hanging above to be fixed. The glass water drops into the mold, and then turns to the bottom of the punch when the punch falls to press the glass into shape, and then takes it out manually and puts it into the annealing kiln, and the finished double-layer glass comes out.
Of course, with the continuous development of science and technology, the production method of Double Wall Glass Cup from China also keeps pace with the times, and the production process is more advanced. Of course, if you have some special requirements for the glass, you can also customize one to make the glass meet your own preferences.
