The Process:

  1. The PET Granules, previously dehumidified for about 4 hours in a drying hopper dropped at about 170 deg C into a special screw called the extruder. The extruder rotates continuously and is kept at a settled temperature by means of heat resistance, plasticizes the PET, and transfers it into a central distributor. The distributor will lead the melted material through hot channels into the shooting pads
  2. The shooting pads (injectors) will inject at a pressure and speed which can be adjusted, the melted material at about 280 deg C into the hot runner and the preformed cavities of the injection molds. Once the cycle time is expired; the molds open up and the preforms can be extracted from them by means of the transfer device. The cycle time is the time needed for the melted PET to cool down inside the injection mold and form the performance. The preform neck is cooled down to low temperatures and the body temperature to about 105 deg C. Cycle time is related to the preform thickness which depends on the weight and specifications of the final container.
  3. The preforms are handled by means of neck carriers and lead to heaters to heat up the under-neck part permitting to maintain or complete the ideal thermal profile of the preforms for the following stretch-blowing treatment. The heaters can be either heating resistances or hot air exhausted by special devices called air knives.
  4. The heated preforms are introduced into the blowing cavities of the blow mold. In the first stage, a mechanical and pneumatical device stretches the performance by means of stretch rods and low-pressure air, at the second stage the same device blows high-pressure air to give the performance the final bottle shape.
  5. An eject system discharges in bulk the blown containers through a slide. The PET drying hopper, as well as all the functions of the machine, the production parameters, and the cycle time, are controlled by a PLC, complete with a monitor and an alphanumeric keyboard. The Temperatures, pressures, and speed of rotation of the extruder are controlled and regulated by a special feedback system that guarantees the consistency of the process. The machine is equipped with a self-diagnostic program complete with synoptic tables and precise indications of any faulty components or incorrect process parameters.
