Production process of bottle blowing machine

1. Preheating

The preform (embryo) is irradiated by an infrared high-temperature lamp tube to heat and soften the body part of the preform (embryo). In order to maintain the shape of the bottle mouth, the mouth of the preform (embryo) does not need to be heated, so a certain The cooling device performs cooling operation on it.

2. Blow molding

In this stage, the preheated preform (embryo) is placed into the blow mold that has been prepared, and the inside is inflated with high pressure, and the preform (embryo) is blown into the required bottle.

Blow molding machines on the market are generally divided into two types: fully automatic and semi-automatic.

The automatic bottle blowing machine combines the two operations of bottle blowing through the operation of the manipulator, eliminating the need to manually put the preheated preform (embryo) into the blow mold. The production rate is greatly accelerated, and of course the price is higher than that of semi-automatic ones.
