Blow Molding Machine

First Level

Second Level

There is not much difference in quality, but the bottle blown out by the fully automatic machine is slightly better than the semi-automatic, mainly due to factors such as temperature control, timely program analysis, and fast action transmission.

Fully automatic bottle blowing machine

High price, high output, labor-saving, and requires good technical personnel to maintain. The automatic efficiency is high, and the quality is usually relatively stable because there is no influence of the operator.

Semi-automatic bottle-blowing machine

Small investment, easy operation, simple maintenance, low output, and high labor intensity.

The quality of the blown bottles is the same, the difference lies in the operation process, the operation of the semi-automatic bottle-blowing machine is more, it needs to be watched by people, and can be adjusted at any time, the efficiency of the automatic bottle blowing machine is high, it is just copying.

Working principle of bottle-blowing machine

  • Preheating:
    The preform is irradiated by an infrared high-temperature lamp to heat and soften the bad part of the preform. In order to maintain the shape of the bottle mouth, the preform mouth does not need to be heated, so a certain cooling device is required to cool it operate.
  • Blow molding:
    In this stage, the preheated preform is placed in the blow mold that has been prepared, and high-pressure inflation is carried out inside it. Blow and stretch the preform into the desired bottle. 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 into the blow mold. Greatly accelerated the rate of production.
