The single-stage equipment has an extruder that injects a parison right into a preformed mold that cools the preform quickly to generate the desired kind. After cooling, this stretch strike molding maker reheats the preform, adhered to by positioning it in the bottle mold and mildew. As the parison softens, it stretches to approximately twice its original length.

At that point, the machine pressures pressed air into the now stretch parison, expanding it to the mold and mildew shapes and size. Once more, the item cools down and also the cover of the mold and mildew opens, disclosing a plastic bottle with a hollow interior. For specialty items like wide-mouthed containers and also reduced manufacturing rates, stretch blow molding producers generally make use of the single-stage equipment.

Unlike single-stage stretch impact molding equipments, those in the two-stage group deal with an already made preform. Starting with a made and also cooled preform, pressed air stretches out the plastic to the size and shape of the mold, after which time the machine ejects it.

Of both options, this is the most pricey. Therefore, stretch strike molding producers utilize it for high manufacturing runs. Some examples of the sorts of items this maker makes are narrow-mouthed canteen, alcohol containers, as well as wide-mouthed peanut butter jars.
