- Blow molding ( BrE moulding ) is a production method by which hollow plastic elements are fashioned. In standard, there are 3 key kinds of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding method begins with melting down the plastic and forming it into a parison or in the scenario of injection and injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in a person conclusion by means of which compressed air can go.
The parison is then clamped into a mold and air is blown into it. The air stress then pushes the plastic out to match the mold. When the plastic has cooled and hardened the mold opens up and the component is ejected.
