KoAx-S-Truder - a new extrusion concept with coaxial screws and melt separation
An alternative way to get high and constant plasticizing capacities without using larger screw diameters or longer processing units can be reached with a new plasticizing concept. With a separately driven coaxial feeding screw the decrease of throughput rate especially for materials with varying physical properties and higher screw speeds can be reduced in a wide range. The following separation of solid material and melt within the short transition zone leads to high plasticizing capacities and lower melt temperatures by reducing the induced shear energy caused by the rotating screw.

The Journal of Plastics Technology is a peer reviewed internet periodical published under the auspices of the Scientific Alliance of Polymer Technology (WAK)
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
The Journal of Plastics Technology is indexed in SCOPUS, the largest abstract and citation database of peer-reviewed literature.
