How are plastic bottles made?

Answer:

First of all, to design, determine and manufacture molds, glass raw materials to quartz sand as the main raw material, and other accessories at high temperature dissolved into liquid, and then injected into the mold, cooling, incision and tempering, forming glass bottles. Glass bottles generally have rigid signs, signs are also made of mold shapes.
This stage is to put the preheated preform into the ready mold and charge it with high pressure to blow the bottle into the desired bottle.Bottle blowing machine in the market is generally divided into two kinds of automatic and semi-automatic. The automatic bottle blowing machine completes the two operations of the bottle blowing by the operation of the manipulator, and eliminates the process that the pre heated bottle embryo is put into the mold by the artificial hand. Greatly accelerated the rate of production, of course, the price is also higher than semi automatic.
The bottle embryo is irradiated by a high temperature lamp tube to heat and soften the part of the bottle embryo. In order to keep the bottle mouth shape, the bottle embryo mouth needs no heating, so a cooling device is needed to carry out the cooling operation.
