This work deals with the melting of polymeric materials and the melt penetration into the solid bed utilizing a model experiment that simulates the melting process in single screw plasticating units. Polymer granules are pressed onto a heated rotating shaft. The thickness distribution of the resulting melt film is measured according to the principle of optical triangulation (light intersection). This new method and the measurement of the density of bulk using a piston position measurement were presented earlier by the authors. The combination of these different principles allows the determination of the melt penetration into the solid bulk as it takes place in single screw plasticating units.
