The production process Blow-moulding is used to produce different kinds of bottles in plastic. The final stage in this process is the inflation of some kind of (extruded or injection moulded) cylinder outward against the wall of the mould. This creates the final shape of the product. The inflation is performed applying a gas pressure into the core of the cylinder, which press the molten plastic cylinder outward. During the inflation the plastic may burst. The occurrence of this burst, or break, puts a limit on the possibility to produce a specified product at some, or all, processing conditions. Here the purpose is to investigate and understand the burst.
