An apparatus for forming plastic preforms into plastic containers, includes at least one forming station which forms the plastic preforms into the plastic containers by applying a flowable medium to the plastic preforms, wherein the forming station includes a blow mold, and a rod-like body which is insertable into the plastic preforms via a mouth of the plastic preforms, and a moving device which is configured for moving the rod-like body in the longitudinal direction of the plastic performs. The rod-like body has a channel for guiding the flowable medium, and the forming station has a valve device controlling the supply of the flowable medium into the channel. The valve device is arranged on the moving device and/or a ratio between an inner diameter of the rod-like body and an outer diameter of said rod-like body is, at least in sections, smaller than or equal to 0.5.

Hollow part manufacturing machine includes at least one mold in which hollow parts can be manufactured by application of a pressurized medium, a valve unit, having at least two valves, wherein an inlet of a second valve is connected to a second pressure accumulator, which is pressurized under a second pressure, and an outlet of the second valve is connected to a blow nozzle via a channel. The inlet of a first valve is connected to a first pressure accumulator that is under a first pressure and the outlet of the first valve is also connected to the blow nozzle via a channel. During at least a part of the molding process, the blow nozzle seals the material to be molded, and/or the mold, relative to the environment.

An apparatus for forming plastic preforms into plastic containers, includes at least one forming station which forms the plastic preforms into the plastic containers by applying a flowable medium to the plastic preforms, wherein the forming station comprises a blow mold (26), and a rod-like body which is insertable into the plastic preforms via a mouth of the plastic preforms, and a moving device which is configured for moving the rod-like body in the longitudinal direction of the plastic performs. The rod-like body has a channel for guiding the flowable medium, and the forming station has a valve device controlling the supply of the flowable medium into the channel. The said valve device is arranged on the moving device and/or a ratio between an inner diameter of the rod-like body and an outer diameter of said rod-like body is, at least in sections, smaller than or equal to 0.5.

An apparatus for producing plastic containers filled with a liquid, having a forming device which forms plastic preforms into containers, and a filling device which fills the containers with the liquid, wherein the filling device has a transport device which transports the containers during their filling and a plurality of filling devices which fill the containers. The apparatus has a supply line in order to supply the liquid to be filled to the filling devices, wherein the apparatus has at least one heat exchanger device which is configured to also use the liquid to be supplied to the filling devices for cooling components of the forming device and/or a further treatment unit.

A method for operating a molding machine includes providing dependencies between, in particular unsorted and/or partially circularly interdependent, actions for performing at least one task. The at least one task is or comprises an operation, a startup or shutdown, a maintenance and/or an optimization of a molding process and/or a molding machine and/or a mold. The method further includes sorting the actions based on the dependencies between the actions.

A container treatment system includes a production machine for preforms, a blow molding machine and at least one heat exchange device. The production machine and the blow molding machine are interlocked with one another, and the at least one heat exchange device is configured for heat exchange between the production machine and at least one component of the container treatment system.

A container treatment system includes a manufacturing machine for preforms, a blow molding machine, and at least one heat recovery device. A first process medium can be supplied from the manufacturing machine and/or the blow molding machine to a first heat recovery device. Heat can be exchanged between the first process medium and a second process medium of the container treatment system using the first heat recovery device.
