Method for forming plastic preforms into plastic containers, wherein a plastic preform is introduced into a blow mould and is expanded into a plastic container by being applied by a flowable medium, wherein the plastic preform is applied by at least two different pressure levels and wherein furthermore preferably a rod-like body is introduced into the plastic preform, in order to expand the plastic preform in its longitudinal direction, wherein a pressure curve and/or a movement curve of the rod-like body being determined by a measuring device during the expansion process, wherein

Method and apparatus for forming plastic preforms for plastic containers with curve evaluation

A forming unit () for forming plastic preforms into plastic bottles, wherein the forming unit comprises a blow mould () having a first lateral portion (), a second lateral portion () and a bottom portion (), wherein said lateral portions as well as the bottom portion () form a cavity (), within which the plastic preforms () can be formed into the plastic bottles, wherein the bottom portion () can be moved relative to the lateral portions () in a closed condition of the blow mould, wherein the forming unit () comprises a drive unit in order to move the bottom portion () relative to the lateral portions (), wherein the drive unit preferably has a movable piston element () which ist movable along a predefined stroke path. According to the invention, the apparatus has a first stroke path limiting means () that limits the stroke path of the bottom portion () and/or of the piston element () in a first direction, wherein this stroke path limiting means () is adjustable in order to modify the stroke path.

Apparatus and a method for forming plastic preforms into plastic bottles with a movable bottom portion

Provided is an apparatus for heating plastic parisons, including a transport device or transporter, which transports the plastic parisons at least in sections along a predefined transport path, wherein the transport device or transporter has a plurality of holding devices or holders for holding the plastic parisons, with a heating device or heaters for heating the plastic parisons at least at times, while they are being transported by the transport device or transporters, wherein the apparatus has at least one heat shielding device or heat shield which is suitable and intended to counteract the heating of mouth regions of the plastic parisons.

Apparatus for heating plastic parisons with a shielding panel

A method for forming plastic preforms into plastic bottles includes introducing a plastic preform to be expanded into a blow mould, wherein this blow mould has at least two side parts and a bottom part which is movable in a longitudinal direction of the plastic preform in relation to these side parts; introducing a rod-shaped body through a mouth of the plastic preform into the interior of the plastic preform; applying a first pressure to the plastic preform; applying a second pressure to the plastic preform, wherein this second pressure differs from the first pressure and is higher than the first pressure; applying a third pressure to the plastic preform, wherein this third pressure differs from the second pressure and is higher than the second pressure. After applying the third pressure to the plastic preform, the bottom part is moved in the longitudinal direction of the plastic preform towards the latter.

Method and apparatus for blow moulding of containers with a movable base part

A method for transforming plastic preforms into plastic bottles, in which preforms are introduced into blowing stations, each blowing station having at least one blow mold and a stretching rod for stretching the preform along a longitudinal axis of the preform within the blow mold, and the preforms are expanded to form the plastic bottles by being acted upon by a gaseous medium in the blow mold, wherein a wall thickness of the plastic container is measured by at least one measuring device which outputs the measured values to a closed-loop and/or open-loop control device, wherein at least a stretching speed of the stretching rod is varied by the closed-loop and/or open-loop control device at least at times and/or at least in some locations during the blowing operation, individually for each blowing station, in order to adjust a wall thickness of the plastic bottles.

Method for transforming plastic preforms

A method of after-cooling of the bases of blown out containers, wherein after the transfer of the blown out containers from a blow molding machine to a run-out star wheel which directly follows the blow molding machine along a conveying direction of the containers a cooling of the bases of the containers is carried out by at least one apparatus for cooling the bases. The cooling of the bases of the containers starts immediately during a time interval of at least 0.1 seconds and at most 2 seconds after a pressure release of the containers by the blow molding machine after the blowing out.
