Verfahren und Vorrichtung zum Verformen von Hohlkörpern aus thermoplastischem Material

摘要

According to the inventive method for shaping hollow bodies made of thermoplastic material which comprise at least one gas pocket (3) having a wall (6), said wall (6) of the gas pocket(s) (3) is externally subjected to the action of pressure in all-over manner, and the hollow body to be shaped is heated when the wall (6) of the gas pocket(s) (3) is being externally subjected to the action of pressure. A device is configured for carrying out the inventive method. The inventive method or device prevent an undesired deformation or a bursting open of the wall of the gas pocket(s) when heating the hollow body.
