    摘要: A method for forming plastic preforms into plastic containers using at least one device for forming preforms into containers, wherein preforms are acted upon by a flowable and, in particular, gas-forming medium and are formed into the containers, wherein the preforms are acted upon with different pressure levels and the flowable medium is stored in at least two reservoirs and is supplied from these reservoirs to the preforms and at least one of these reservoirs is supplied with the flowable medium by a pressure supply device, wherein the target pressure in at least one reservoir is controlled, and wherein this target pressure is compared with an actual pressure in this reservoir. A value characteristic of this comparison is determined. An offset value is controlled on the basis of this value and is controlled in such a way that a predetermined pressure and the target pressure is set in the reservoir.

    摘要: An apparatus for forming plastic preforms into plastic containers with at least one forming station which forms the plastic preforms into the plastic containers by the action of a flowable medium, wherein the forming station has a blow mould which forms a cavity, within which the plastic preforms are formed into the plastic containers. The blow mould has a base part which has an inner contour which forms a base of the containers, wherein the base part has at least one channel for conducting a temperature control medium for temperature control of the base part. A course of the channel is adapted to a course of the inner contour and/or the channel has, on its inner surface facing the temperature control medium, structures and/or cross-sectional changes which influence the flow of the temperature control medium through the channel.
