AUTOMATIC PET BOTTLES BLOWING MACHINES

The model range of machines for blowing bottles made of polyethylene terephthalate over the past few years has been replenished with new high-tech equipment, surpassing the products of famous foreign companies in a number of parameters. The speed of operation of the most productive PET bottles blowing machines has reached 12 000 bph, or 1500 – 1800 finished products from one cavity.

Such performance is achieved by improving the control electronic modules and ensuring high accuracy and speed of operation of pneumatic systems. In addition to performance, an important characteristic of machines for the production of PET containers is the size range, and according to this indicator, the equipment fully covers the needs of the market. Customers can pick up and purchase blow molding machines that work with containers with a volume of 0.25 to 30 liters or more.

Features of construction of automatic machines for blowing PET containers

The main difference between this equipment and semi-automatic systems is the complete mechanization and automation of all stages of production. These operations include:

  • Loading of preforms from the hopper with subsequent orientation, quality control and moving of preforms to the heating zone.
  • Primary preform heating when passing through a temperature-controlled furnace.
  • The process of balancing, which consists in equalizing the temperature indicators over the entire thickness of the preforms.
  • Final heating and feeding of moving groups of preforms into the cavity of the mold that has just opened and released from the finished container.
  • Stretching of heated preforms placed in the mold cells with special metal rods, and blowing under the action of air injected at a pressure of 25, and at the final stage — up to 40 bar.
  • Rapid cooling due to contact with cold metal and fixation in a new size of blanks inflated to the size of mold cells.
  • Unloading of finished products from the opened mold.

Automatic machines for blowing PET bottles are flexibly configured from a convenient touch panel or control terminal and operate autonomously, requiring only periodic monitoring by the operator.
