Abstract: 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.

Abstract: Method of manufacturing containers by blow-moulding preforms, including a phase of heating the preforms (3) followed by a phase of forming the containers (this phase including a pre-blowing step followed by a blowing step), this method including the operations consisting in: detecting a pressure spike during the pre-blowing and comparing it against a reference spike, if the pressure in the pressure spike is below the reference pressure, checking an event history to determine whether a heating instruction and/or a forming instruction has been modified; if the result of this check is positive, commanding at least one of the following actions: ∘ generating an alert alarm, ∘ stopping the supply of preforms to the oven, ∘ ejecting the containers derived from the affected preforms.

Abstract: The present invention relates to a method for manufacturing containers from thermoplastic materials by blow moulding or extrusion blow moulding a preform that has been pre-heated in a furnace then placed in a mould consisting of two half-moulds that define a moulding cavity, said preform being blown into the mould, optionally with a pre-blowing step. Said steps of heating the preforms, pre-blowing and blowing are controlled by a control unit on the basis of various control parameters such as the temperature in the furnace, the blowing pressure in the mould and/or the pre-blowing pressure and/or the pre-blowing flow rate and/or the speed of the stretching rod, for example. Said method is characterised in that it comprises at least the following steps: i) measuring the wall thickness of said containers at at least two different heights upon exiting the mould; ii) comparing the thickness measurements with setpoint values determined for each height of the containers; iii) if the difference between the thickness measurements and the determined setpoint values is greater than a determined threshold, modifying at least one of the control parameters, said modified control parameter(s) being selected at least by calculating the theoretical effects of the variation for each parameter on the thicknesses, then selecting the parameter or parameters that cause the smallest difference between the measured thickness values and the theoretical thickness values; iv) steps i) to iii) are repeated until the differences between the thickness measurements and the determined setpoint values are below said determined threshold.
