In addition to cold work in the deep processing of glass bottles, glass bottle factories are more commonly used is hot work, that is, in the melting point (1450 degrees) and Xu cold point (450 degrees) between the production method.
The molding method will be injected into the molten hot glass paste has been engraved into the pattern mold into a block at the same time the pattern is also pressed. In sand mold casting, the model is pressed into the sand with moderate depth and sprayed with wet acetylene to avoid the sand mold collapsing. The glass paste is put into the sand mold until the glass is slightly cold, then taken out and cooled, and then ground for processing. One of the earliest techniques used to make glass Windows is to first mix soil and horse dung to make the pericardium, then dip hot glass paste into the metal rod to become the main body of the container. Then wrap the glass wire around the outer image to outline the pattern. After the creep and cooling, the germ center is dug out.
Torch thermoplastic with a small spray gun or torch heating, also known as the torch thermoplastic, only colored boron glass or sodium glass color rod, to elongate, twist, wire winding and other skills, continuous combination of modeling, suitable for small delicate performance, such as glass beads, animals and plants. And because of the different use of glass rod is divided into: solid, hollow and brushed thermoplastic, in addition to the color can also be matched to increase the interest of the work.
In the dewaxing casting method, after the wax mold is covered with refractory gypsum, the glass raw material and the empty mold are put into the furnace at the same time for heating, and the glass slowly flow into the mold for forming at high temperature. The glass is placed in the furnace for dewaxing, and the plaster mold is removed by Xu Leng and then finished by grinding and polishing. In powder casting method, glass blocks and glass powder are filled into the pre-designed model and put into the furnace to heat up and melt into the whole glass work.
Finally, there is a common glass bottle factory manufacturing process that everyone is familiar with - blowing. Blowing originated in the Roman Empire in AD, and is still the most important, widely used and varied method of making glass. Blowing mainly to the window, the process refers to the blowing pipe with molten glass paste, blowing to form a bubble, and then the use of tools to be hot molded, and then another blowing pipe with a small amount of glass for bridging the bottom action, knock down the work Xu cold.
