摘要: An extruder screw for the plasticizing of at least one plastic material or a plastic material mixture, with a melting zone, a wave zone and a mixing zone arranged between the melting zone and the wave zone, wherein a conveying web extending in a helix-like manner along a screw longitudinal axis is formed in the melting zone and in the wave zone, wherein a conveying web of the melting zone terminates at an end of the melting zone facing the mixing zone, and a conveying web of the wave zone begins at an end facing the mixing zone. The application also relates to an extrusion device with this extruder screw, and a method for plasticizing at least one plastic material or a plastic material mixture.

摘要: An extruder screw for plasticizing at least one plastic or plastic mixture, including a melting zone, a shaft zone and a mixing zone arranged between the melting zone and the shaft zone, wherein a conveying flight is formed in the melting zone and in the shaft zone, which extends helically along a longitudinal axis of the screw, wherein a conveying flight of the melting zone ends at an end of the melting zone towards the mixing zone and a conveying flight of the shaft zone begins at an end towards the mixing zone. A flight depth of the melting zone continuously decreases along the longitudinal axis of the screw to the mixing zone. Further, an extrusion device having the extruder screw and to a method for plasticizing at least one plastic or plastic mixture.
