ABSTRACT:
The procedure serves the purpose of molding a container from a thermoplastic material. After a temperature treatment a moldable object is fed to a blow station, which has a blow mold that is provided for the purpose of contouring the container. The temperature-treated moldable object is inserted into the blow mold. By feeding in high-pressure blow air, the moldable object is expanded. In addition at least one other pneumatic working step with low-pressure air is carried out, with this air being taken from a low-pressure air supply. The low-pressure air supply has a smaller pressure level than the high-pressure blow-air supply. After the moldable object has been expanded, high-pressure blow air streaming out of the molded container held in the blow mold is fed to the low-pressure air supply during a transition phase. In the region of the low-pressure air supply a pressure monitoring is carried out for the purpose of defining a maximum low-air pressure to be provided. After the transition phase a venting of the container that is held in the blow mold is performed vis-a-vis an ambient pressure.
