Abstract
A forming station comprising a source of pressurized forming fluid, and an injection device comprising an inlet, in fluidic communication with the source of pressurized forming fluid, and an outlet in fluidic communication with the inlet and through which the forming fluid is intended to be injected in the preform and further comprising a stretch rod movable in translation according to the axis of the stretch rod relative to the outlet and arranged to assist the axial deformation of the preform during a stretching phase. The forming station further comprises a vibratory device connected to the stretch rod, arranged to vibrate the stretch rod when said vibratory device is actuated, and a control device arranged to actuate the vibratory device during at least a part of the stretching phase.
