The melting process of the material is optimized, so as to increase the extrusion yield and realize the extrusion of the material melt at a lower temperature.
Good homogenization of the material is achieved by the specific shear action in the isolation gap.
The melt plasticization process is controlled, meaning that only particles smaller than the isolation gap can enter the melt channel.
