A method for manufacturing containers from thermoplastic materials by blow molding or extrusion blow molding a preform that has been pre-heated in a furnace then placed in a mold consisting of two half-molds that define a molding cavity, said preform being blown into the mold, optionally with a pre-blowing step. In example embodiments, the method includes at least the following steps of: i) selecting at least one production configuration from a GUI (graphical user interface), each production configuration being associated with one or more control parameters; ii) compiling the various control parameters corresponding to the selected production configurations; and iii) executing said selected and compiled control parameters. In other example embodiments, the invention relates to computer program product, a data processing device, and a computer-readable storage medium implementing the steps of the method.

The method and the device are used for blow-molding containers. A preform made of a thermoplastic material is first subject to a thermal conditioning operation along a transport path in the region of a heating section. Thereafter, the preform is formed into the container inside a blowing mold by applying blowing pressure. While the preform is shaped into the container, at least one parameter (49, 50) characterizing the shaping is measured and evaluated by a control unit. Depending on said evaluation, at least one controlled variable (48, 46) influencing the shaping operation inside a closed loop is varied in order to match the measured parameter to an associated target value. In this way, it becomes possible to subject the container parison developing during the blow-molding operation to a predetermined defined development.
