  • temperature control is carried out in the conditioning section, but not for each individual preform but for groups of preforms.
  • the conditioning section can be, for example, an oven with infrared radiators or a microwave oven. If necessary, cooling can be carried out by air, sterile air, inert gas or also solids, such as dry ice, for example. Passive cooling by creating an equalizing section is also conceivable.

  • the preforms are preferably transported in such a way that they always have a defined division to the next preform. This can advantageously be achieved by transporting them by means of holding clips, for example in the area of their mouth.
