Gestión de Compras designs, develops and manufactures Pet Preforms for various sectors.


The PET preform, better known as “preform”, is accomplished through a molding process. The fused PET injected into a mold become a preform, which, by an additional processing step (blowing), takes the form of bottles for beverages for elementary, oil or detergents use.

Methods

The One-Stage Method

This method goes from PET granule to finished bottle on one integrated machine. This means the injection-moulded preform is withdrawn from the injection cavity while still hot enough to be stretch blown to form the bottle. One-Stage method is suited to small and medium scale production lines.

The Two-Stage Method

This method uses two separate machines, an injection moulding machine for making the preforms and a reheat blow moulding machine to reheat the preforms from a cold state and blow the bottles. This method is most suited to medium to large-scale production.

Process

  1. Drying of PET
  2. Plasticizing the PET
  3. Injection Molding the PET Preform
  4. Heating the PET Preform
  5. Stretch Blow Molding the PET Container
  6. PET Container/Bottle Ejector
