YUANYOU Committed to stable performance automatic PET bottle blowing machine production line since 1990s.

The process of blowing machine bottle

The process of the bottle blowing mechanism: 1. Preheating: the preform is irradiated by an infrared high-temperature lamp, and the body part of the preform is heated and softened. In order to maintain the shape of the bottle mouth, the preform mouth does not need to be heated, so it needs certain cooling device to cool it. 2. Blow molding: During this period, the preheated preform is placed in the blow mold that has already been prepared, and high-pressure inflation is carried out in it, and the preform is blown and drawn into the desired bottle. Blow molding machines on the market are generally divided into two types: automatic and semi-automatic. The automatic bottle blowing machine completes the two blowing operations together through the operation of the manipulator, eliminating the process of manually placing the preheated preform into the blow mold in the middle. Greatly accelerated the rate of production, of course, the price is higher than the semi-automatic.
