A method of shaping plastics material pre-forms into plastics material containers with the steps: According to the invention the pre-set point in time (t) is variable.

Blow-moulding machine with automatic optimization of the process angle

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:

Blow moulding machine with variable intermediate pressure level

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.

Blow mold

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.

Air recirculation in a blow molding process

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.
