A method and device for forming plastic preforms into plastic containers has a plurality of forming stations each having application devices which apply a flowable medium at least a first pressure level, a second pressure level, a third pressure level and a fourth pressure level respectively, wherein the second pressure level is higher than the first pressure level, the third pressure level is higher than and the second pressure level and the fourth pressure level is higher than the third pressure level and wherein at least at times a bottom area of the plastic preform and/or plastic container is applied with the flowable medium.
A method for forming plastic preforms into plastic containers wherein a transport device transports the plastic preforms along a predetermined transport path, wherein the transport device has a rotatable transport carrier on which a plurality of forming stations for forming the plastic preforms into the plastic containers is arranged, wherein the forming stations each have a stretching rod with which the plastic preforms are stretched in their longitudinal direction and each have application devices which apply the plastic preforms with the flowable medium and wherein the apparatus has at least four pressure reservoirs which store the flowable medium and the plastic preforms are applied for their expansion with at least a first pressure level stored in the first pressure reservoir, a second pressure level stored in the second pressure reservoir, a third pressure level stored in the third pressure reservoir and a fourth pressure level stored in the fourth pressure reservoir, wherein the third pressure level is higher than the second pressure level and the fourth pressure level is higher than the third pressure level and wherein at least at times a bottom area of the plastic preform and/or plastic container is applied with the flowable medium through the stretching rod.
An apparatus for forming plastic preforms into plastic containers with a transport device which transports the plastic preforms along a predetermined transport path, wherein the transport device has a rotatable transport carrier on which a plurality of forming stations for forming the plastic preforms into the plastic containers is arranged, wherein the forming stations each have a stretching rod with which the plastic preforms are stretched in their longitudinal direction and have application devices which apply the plastic preforms with the flowable medium and wherein the apparatus has at least four pressure reservoirs which store the flowable medium and the plastic preforms can be applied with at least a first pressure level stored in the first pressure reservoir, a second pressure level stored in the second pressure reservoir, a third pressure level stored in the third pressure reservoir and a fourth pressure level stored in the fourth pressure reservoir, wherein the second pressure level is higher than the first pressure level and the third pressure level is higher than the second pressure level and the fourth pressure level is higher than the third pressure level and wherein the apparatus has a bottom application device which is suitable and intended for applying the bottoms of the plastic preforms and/or plastic containers with the flowable medium during the expansion process.
