Injection Blow Moulding (IBM)

The process of injection blow moulding (IBM) is a combination of blow moulding and injection moulding.

IBM is normally used for the production of hollow glass and plastic objects such as packaging in large quantities. In the IBM process, the polymer is injection moulded onto a core pin, then the core pin is rotated to a blow moulding station to be inflated and cooled. The process is divided into three steps: injection, blowing and ejection.

The advantages of IBM over either Blow or Injection Moulding as standalone processes include:
   •  IBM is ideal for the use of virgin, pure materials,
   •  IBM produces a better and consistent quality finish, particularly in the neck and base of bottles,
   •  IBM requires no trimming, no handling and a more assured hygienic production process,
   •  The IBM process can manufacture larger quantities than either blow or injection moulding.

Sogeplast is one of the very few packaging manufacturers in South Africa who make use of the more costly but more sophisticated and effective IBM technology to ensure better packaging solutions to our clients.

Our IBM machines combine injection process and blow process in continuously molding steps, which assures the fine bottle products with uniform wall thickness, precise molded neck tolerances, glossy finishes, furthermore, without any trimming of the neck or bottom. Automatic products ejection, automatic flame treatment and automatic counting devices make sure products not to be polluted, to reach up the health requirement of food and pharmaceutical industry.

Our IBM machines enjoy high reputation for their reliable structures, low consumption of energy, low cost of moulds and convenience to replace the molds. All components, such as hydraulic, pneumatic and even electrical components, used in our IBM machine are totally introduced from world famous qualified manufacturers. So the continuously high efficient operation can be guaranteed.

Our Injection Blowing Machines (IBM) are specially designed to make bottles/containers/jars & tubes for packing of medicine, food, cosmetics and chemical products ranged from 2ml to 500ml.

Using hot runner system and high-pressure injection, assure the accuracy of mouth, neck and thread. No half line and wasted material occur at the mouth or bottom of the bottle products, which saves raw material and ensures uniform structure and smooth surface.
