The process of blowing bottles

Firstly preheating

The preform (embryo) body part is heated and softened through a high-temperature infrared lamp. In order to maintain the shape of the bottle mouth, the preform (embryo) neck does not need to be heated, so a certain cooling device is needed to cool it.

Secondly, blowing bottle forming

In this stage, the preheated bottle preform (embryo) is placed into the blow mold that has been completed, and the high-pressure inflation is carried out inside to blow and pull the bottle preform (embryo) into the required bottles.

The bottle blowing machine on the market is generally divided into automatic and semi-automatic two kinds.

The automatic bottle blowing machine completes the two operations of bottle blowing together through the operation of the manipulator, eliminating the process of manually putting preheated bottle preform (embryo) into the blowing mold in the middle.Greatly accelerated the rate of production, of course, the price is higher than semi-automatic.
