Many people are aware that there are different molding systems, but few clearly understand the unique properties of each type. The process of injection blow molding (IBM) is used for the production of hollow glass and plastic objects in large quantities. In the IBM process, the polymer is injection molded onto a core pin; then the core pin is rotated to a blow molding station to be inflated and cooled. This is the least-used of the three blow molding processes, and is typically used to make small medical and single serve bottles. The process is divided into three steps: injection, blowing and ejection.
As with any manufacturing system there are pros and cons, here are a few for injection blow molding.
