INLINE MEASUREMENT OF THE MELT QUALITY HYPERBOLIC SLOT DIE Innovative and patented Intelligent process monitoring How often does the melt quality drop during a compounding process – without the operator immediately recognizing it? More often than you might think! There are many reasons for quality reduction: Perhaps the polymer or filler used in the extrusion process comes from another batch. Maybe the side feeder was clogged without anyone noticing. In order to be able to constantly assess the melt quality, the decisive key data must be determined during the process. Up to now, only...

TECHNICAL INFORMATION Visualization of measurement results The Leistritz elongation rheometer is available as process monitoring or as research version, with different evaluation and control software: The research version can automatically determine complete elongational and shear viscosity curves by processing a pre-defined volume throughput, and provides direct access to the recorded data. Using this process variant, you can determine the MFR and IV values. In addition, this version enables you to correct the viscosity data according to Weissenberg-Rabinowitsch and Cogswell. With the...
