The production of glass cups is mainly divided into manual blowing and machine pressing according to the production method.

Artificial blown glass

The original should be a hand-blown glass, use a stainless steel hollow tube to pick a proper amount of high-temperature molten glass water, blow it into a spherical shape like a balloon, and then put it into a previously prepared mold to continue to blow into the mold. Fit the shape, then open the mold, clip the cup into the annealing furnace to remove the stress of the glass, and then cut, edging, mounting (foot or handle), polishing, is the finished glass.

The principle that the machine blows the glass is the same as the manual, but it is blown by a person into a bubbler.

Pressed glass

Pressing the glass machine molds are fixed on the turntable one by one. The turntable usually has 8 or 10 molds. One punch is suspended above the top. The glass is dripped into the mold through a barrel, and then transferred. When the punch is under the punch, the glass is pressed and formed, and then the glass is manually taken out and placed in the annealing furnace. The finished glass is the finished glass.
