Method and device for the production control of an extruded plastic product and extrusion system for extruding such a plastic product

A method for the production control of an extruded plastic product with the following steps: recording at a first measuring point a first actual temperature of a measuring area provided on the plastic product, recording a second actual temperature of the measuring area at a second measuring point which is arranged at a distance from the first measuring point in a direction of extrusion of the plastic product, determining a setpoint temperature of the measuring area at the second measuring point, and outputting information on whether the second actual temperature is inside or outside a prescribed tolerance range of the setpoint temperature.

Method and apparatus for forming plastic preforms into plastic containers with pre-heating of blow moulds

Method for operating an apparatus for forming plastic preforms into plastic containers, wherein in a working mode a plurality of forming stations are moved along a predetermined transport path by a movable carrier, wherein these forming stations in each case having blow mould arrangements which in a closed state in each case form cavities, within which the plastic preforms are formed into the plastic containers and the plastic preforms are supplied to these forming stations in order to be formed by supplying a flowable medium to the plastic containers, wherein this forming takes place at least temporarily during the transport of the forming stations along the transport path, and wherein at least temporarily at least components of the blow moulding arrangement are tempered. At least parts of the blow mould are pre-heated in a standstill of the carrier or a movement of the carrier, which is slower with respect to a movement of the carrier in the working mode.
