Abstract: A device for blow molding containers. Preheated preforms made of a thermoplastic material are transferred within a blow molding machine to a blowing device. In the region of the blowing device, the preforms are shaped into containers by the blow molding by a blowing pressure.

Abstract: A method for controlling a blow-molding machine for producing a thermoplastic container, wherein a blowing gas for blow-molding the container is introduced into a thermally conditioned preform, while the preform is held in a blow mold of the blow-molding machine. The blowing gas is introduced during a preblowing phase into the preform so that the temperature-conditioned material of the preform approaches the walls of the blow mold. The blowing gas is introduced during a following finish-blowing phase into the preform so that the temperature-conditioned material of the preform is pressed into the contours of the blow mold walls. The volumetric flow rate of the blowing gas is determined at least during the preblowing phase by an adjustable flow-control valve that can be controlled by a control unit that generates a control signal for adjusting the flow-control valve. The flow-control valve is adjusted as a function of the control signal.
