Rheometers serve in determining the melt viscosity, thus they are an essential element of the permanent quality control during polymer processing.
The Mono Online Rheometer MOR is used for measuring a viscosity curve on polymers. The viscosity is measured by using a melt flow which flows through a round capillary. The melt is either directly taken out of the extruder or as a side flow.
The Wide Range Online Rheometer WROR determines the viscosity of a plastic melt at different shear speeds. The range of shear speeds is very broad due to the 3-capillary concept of COLLIN.
The viscosity curve can be determined online at many points. A triple spindle distribution pump provides an even melt distribution on three capillaries.
