The production process and production process of the glass

The production process and production process of the glass include raw material pre-processing, preparation of the compound, melting, molding, heat treatment and other steps.
Glass production according to the production method classification is mainly divided into two kinds of production process methods such as manual blowing and machine pressing. Hand-blown glass should be the most original hand-blown glass, with a stainless steel hollow tube to pick an appropriate amount of high temperature melting glass water, like blowing a balloon first blown into a ball, and then put into the prepared mold continue to blow into the mold fit shape, and then open the mold, with a clamp to the cup in the fire kiln to recede the stress of the glass, After it comes out, it is cut, edged, installed (foot or handle), and polished to make the finished glass. Machine blowing glass and artificial principle is the same, but by the human blowing into the bubble blowing machine to blow. The glass pressing machine is like a revolver, the mold is fixed on the turntable one by one, the turntable is generally 8 or 10 molds, hanging above the punch is fixed, through a cylinder to drop glass into the mold, and then turn to the punch under the punch to press the glass into shape, and then manually remove the glass into the annealing kiln. What comes out is the finished glass
