Injection Stretch Blow Molding

The Large Volume Parenteral (LVP) market is one of the most competitive pharmaceutical markets. In the production of LVP, quality and cost are two of the main factors one needs to consider. From polypropylene granules melted and injected into pre-forms, all the way down to IV bottle/bag sealing, we have the most cost effective and high quality turn-key solutions.

Some of the main advantages of ISBM systems are the low tool costs, flexibility over a wide range of filling volumes (100 mL – 1000 mL) and shapes, high production rate, high efficiency, zero material waste, lower energy consumption, simple operation, quick change over, and easy maintenance.

Our experience in ISBM includes:

  • ISBM Bottles
  • Bottles ISBM
  • ISBM
  • Injection mold machines for pre-forms
  • Stretch, Blow, Molding machines
  • Hanger welding


ISBM Series: Injection-Stretch-Blow-Molding Machines for Polypropylene (PP) Containers

The ISBM technology is the modern manufacturing trend for Large Volume Parenterals (LVP), both for irrigation and infusion, either in round or shaped Polypropylene (PP) containers (IV plastic bottles and bags).

The polymer granules are first molded into a so-called “pre-form” using an injection molding process; the pre-form includes the neck of the future container, complete with the desired finish and ready for the closure application (welded caps, screw caps, stoppers, and aluminum seals).

The pre-forms are then stretched and blown to the final shape of the container, ready to be transferred to the air blowing, filling, and capping mono-bloc machines, which can be designed also to process oxygen sensitive liquids.

Production rate ranges from 30 – 250 containers/minute.
