Extrusion blow moulding (EBM)

In extrusion blow moulding, the material is extruded into a parison. The parison is then clamped into a mould and blown into its final shape. A typical feature of packaging made using this technology is the welding seam at the base of the bottle.

  • Benefits: variety of designs (round, angular, oval, with handle), flexible production output.
  • Products: bottles and packaging for cosmetics, household products, drinks, and food as well as oils and lubricants.
  • Plastics used: HDPE, LDPE, PP, and extrudable PET.
injection stretch blow moulding two-step process

Injection Stretch Blow Moulding (ISBM) 2-step

Preforms are first produced in the injection-moulding process. In an independent, second step, known as stretch blow moulding, the preforms are reheated and stretch-blown to the final shape in the blow cavity. These bottles have a clearly distinguishable injection point at their base.

  • Benefits: rapid cycle times, high output quantities, in-house and in-line solutions possible.
  • Products: bottles for beverages, home care, and personal care products.
  • Plastics used: PET, PS, PP, PE.

Injection Stretch Blow Moulding (ISBM) 1-step

Preforms are first produced in the injection-moulding process. Directly afterward, the tempered and still soft preform is stretched and blown to the final shape in the blow cavity. In 1-step moulding, these two steps are carried out in one machine. These bottles have a clearly distinguishable injection point at their base.

  • Benefits: premium surface quality, no transfer ring necessary.
  • Products: high-end cosmetics, wide-mouth jars, pharmaceutical packaging.
  • Plastics used: PET, PE, PP, PS, etc.

Injection Moulding (IM)

Injection moulding is the high-pressure injection of the raw material into a mould, which shapes the polymer into the desired form.

  • Benefits: a virtually open choice of shapes and surfaces.
  • Products: individual, technical components and closures.
  • Plastics used: PP, PE, PS, etc.
