To the Measurement and Influences of Process Parameters Variations on the Axial Melt Temperature Profile in the Screw Chamber of an Injection Molding Machine

    Activity: Talk or presentation › Contributed talk › science-to-science

    Description

    Previous attempts to accurately measure the real polymer melt temperature in the screw chamber have failed on account of the challenging metrological boundary conditions (high pressure, high temperature, rotational and axial screw movement). We developed a novel ultrasound system - based on reflection measurements - for the online determination of these important process parameter. The system is compared to an infra-red- (IR-) camera system, measuring the melt temperature during an air shot in front of the nozzle. The recorded data of the measurement systems are used to study the influence of process parameter variations on the melt temperature profile in the screw chamber of a reciprocating single screw plasticizing unit.
