Highly efficient containers of low weight and low cost can be produced by extrusion. First, the round perforated tube (previous shape) is formed by the extruder. The mold cavity, consisting of two parts, closes around the barrier and bounces off one end. Then the compressed air forms a container is cooled and the excess plastic is cut to size.
The injection is carried out in three stages. First, liquid plastic is injected into the mold for consideration. The compressed air is then blown through the core pins to expand the shape. Finally, the containers were moved to the third disposal station.
Stretch molding is used to make containers that are rigid and lightweight. Often used for plastic carbonated drink containers. The separation system is stretched biaxially during blow molding to orient and align the molecules.
