Injection Blow Molding - What’s it about?

From agriculture to automobile, you may notice plastic storage requirements in various sectors. But ever wondered how these containers are produced? A process known as blow moulding is utilized by industries to manufacture products of specific dimensions and for particular applications.

Blow moulding can create different products of varied shapes, having hollow applications.

There are 3 types of blow moulding processes –

Today, let’s talk about the Injection blow moulding process (IBM).

In IBM, the raw material or preform is injection-moulded to form a hollow core pin or mandrel, followed by passing into a second process station while the preform is still hot. Then, the injection mould opens, and the preform goes through rotation. The preform is given a particular shape corresponding to the blow mould form through blowing process in virtue of compressed air.

Injection blow moulding comprises three phases: Injection, Blowing and Ejection.

•    Injection

  The IBM machine consists of an injection barrel and screw assembly that melts the polymer, which is then fed into a manifold. Here it gets injected via nozzles into a heated and hollow preform mould. It becomes the external shape that gets clamped around a core rod governing the internal shape of the preform. The preform comprises a fully-formed bottle neck having a thick tube of polymer forming the body.

•    Blowing

  As the preform mould opens in this step, the core rod is rotated and attached to the hollow, chilled blow mould. The core rod allows the entry of compressed air into the preform, thereby inflating it to the shape of the finished article.

•    Ejection

  The ejection phase of IBM, as the name sounds, rotates the core rod to an ejection position. Once the product is finished, it is stripped off from the core and tested for leakage before packing.



An injection blow moulding machine consists of an integral injection unit and a multi-impression mould assembly where the mould cores are mounted. The neck form is completely moulded in the injection stage with the highest precision. Three sets of core rods allow concurrent preform injection, blow moulding and ejection.
