A method for operating a heating device for thermal conditioning preforms made of a thermoplastic material in which each respective one of the preforms is prepared for a subsequent forming process during which the preforms are formed into containers with a forming fluid fed under pressure into the preforms. The heating device is operated in at least a first operating state and a second operating state. The second operating state is a startup phase of the heating device during which a temperature of the heating device approaches an equilibrium temperature of a thermodynamically stable equilibrium state of the heating device. The first operating state is a continuous operation state following the startup phase. The second operating state is operated with a heating output value that varies over time. Furthermore, the invention relates to a heating device and a machine having a heating device, which are configured to implement the method.

A blow mold high-pressure switching step in a blow molding process of an injection stretch blow molding machine is arranged at the first half portion of the blow molding process, to shorten the injection molding process and improve the moldability. The blow mold high-pressure switching step 61B3 of increasing a mold clamping force for blow molds which have been closed in a blow molding process 61B is configured to be performed at a timing within a time from the start of the upper/lower mold opening step 62A1 for opening upper and lower molds in the injection molding process 62A to release a preform 3P to the completion of the injection mold high-pressure switching step 62A3 for increasing the mold clamping force for the closed injection molding mold.

A plastic molding method comprises moving each part of a plurality of parts along a selected one of a plurality of possible paths through dispensing and molding stations of a molding system. A controller tracks an operating state of each station, selects process stations capable of receiving a part for processing; identifies parts capable of processing at the selected process stations, and assigns individual parts to individual process stations.

Even when the filling rate is high, the surface temperature of molded bottles is kept at a certain temperature or higher, and the bottles can be adequately sterilized with a sterilizer.

A preform is heated, the heated preform is sealed in a neck portion mold, a trunk portion mold and a bottom portion mold at a predetermined temperature range, and the preform sealed in the molds is blow-molded into a bottle. Any bottle is removed which has been molded in the neck portion mold, the trunk portion mold and the bottom portion mold the temperature of any of which is outside the predetermined temperature range, and a sterilizer is blasted to any bottle for sterilization which has been molded in the neck portion mold, the trunk portion mold and the bottom portion mold the temperature of all of which is in the predetermined temperature range.
