First, preheating
The preform (embryo) is irradiated by infrared high-temperature lamp, and the preform (embryo) body part of the preform (embryo) is heated and softened, in order to maintain the shape of the bottle mouth, the preform (embryo) mouth does not need to be heated, so a certain cooling device is required to cool it.
Second, blow bottle molding
This stage is to place the preheated preform (embryo) into the already prepared blowing mold, inflate it at high pressure, and blow and pull the preform (embryo) into the required bottle.
The blow molding machines on the market are generally divided into two types: fully automatic and semi-automatic.
The automatic blowing machine completes the two operations of the blowing bottle together through the operation of the manipulator, eliminating the process of manually putting the preheated preform (embryo) into the blowing mold in the middle. The rate of production is greatly accelerated, and of course the price is higher than that of semi-automatic.
