Abstract: A method of shaping plastics material pre-forms into plastics material containers with the steps: introducing a plastics material pre-form into a blow mold; conveying the blow mold with the plastics material pre-form along a pre-set conveying path; acting upon the plastics material pre-form with a gaseous medium during a pre-set period of time for the expansion thereof, wherein the supply of the gaseous medium is carried out in a controlled manner; and releasing the container from pressure at a pre-set point in time. According to the invention the pre-set point in time (t2) is variable.

Abstract: A method for the shaping of plastics material pre-forms into plastics material containers, wherein the plastics material pre-forms are introduced into a blow mould and are expanded to form the plastic bottles by being acted upon with a gaseous medium in the blow mould, includes the steps of: preliminary blow moulding by acting upon the plastics material pre-forms with a first pressure; intermediate blow moulding of the plastics material pre-forms at a second pressure which is higher than the first pressure; and final blow moulding of the plastics material pre-forms at a third pressure which is higher than the second pressure, wherein at least the second pressure is varied during a working operation.

Abstract: A method for the temperature control and/or regulation of a heating device (10) for preforms (46) made from a thermoplastic material, the method being intended for controlling the temperature of the preforms (46) prior to a subsequent blow molding or stretch blow molding process. The temperature control process includes at least two distinct, consecutive heating stages (12, 14). At least one temperature reading of the preforms after the first heating stage is taken, and deviations of the at least one temperature reading from a specified set point temperature is determined, a first temperature reading of the at least one temperature reading being taken after the first heating stage. Radiators in the second heating stage are regulated or adjusted as a function of the first temperature reading and temperature deviations of the preforms from the specified set point temperature are compensated for prior to exit of the preforms from the heating device.

Abstract: Blow mold for producing plastic containers, having a base body in the interior of which a body of the container to be produced can be accommodated and the inside wall of which completely surrounds the container that is to be produced, such that the blow mold has a ring for supporting a neck of the container with respect to the blow mold, along with a spacer device protruding inward with respect to the circumferential edge of the ring, for preventing the body of the container from coming in contact with the inside wall of the blow mold in the event of tilting of the container with respect to the blow mold.

Abstract: A device for molding a container from a thermoplastic material in which a heated parison is pre-blown by supplying low-pressure blowing air from a low-pressure air supply and then the blow molding is completed by subsequent supply of high-pressure blowing air and in which the high-pressure blowing air flowing out of the container that has been completely blow molded is supplied to the low-pressure air supply via a reversing mechanism during a transitional phase. A pressure monitoring is performed in the area of the low-pressure air supply and in which, after the transitional phase, the container is vented with respect to an ambient pressure whereby the pressure in the low-pressure air supply is controlled by varying the duration of the transitional phase.

Abstract: A device and a method used to temper preforms in the manufacture of bottles, in which a tempering device is provided to selectively and directly temper the preforms, and is inserted into preforms. The method provides that the preforms are directly tempered from the inside.
