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. |
