摘要： A plasticating screw is proposed, with a screw channel, which runs spirally around a screw core, is laterally delimited by a flight (1), (2) and has flow elements (3), (4) that are distributed over its longitudinal direction, extend transversely over the screw channel and comprise a deep section (5) and a compression section (6), rising radially in the longitudinal direction. In order to design a plasticating screw of the type mentioned at the beginning in such a way that its length is reduced and good melting characteristics can be achieved even with little energy input, it is proposed that the compression section (6) forms at least one run-up surface (7), which is inclined towards the flight (1), (2) and is adjoined in the longitudinal direction by a plateau (8) for forming the flow.

摘要： A mixing element for an extruder screw having a width extending in an x-direction of an x-y-z coordinate system, a length extending in a y-direction, and a thickness extending in a z-direction. The mixing element includes a base defining a passage extending along an axis in the y-direction for receiving the extruder screw. Projections extend radially outward from the base and define channels therebetween. The width and the depth of each channel vary along the length of the channel.

摘要： A no solid bed extruder screw for processing a material to a molten state has a body with a helical thread having pushing and trailing surfaces, he body extending longitudinally between feed and discharge ends. A channel for receiving the material to be processed is formed between the body outer surface and an outer diameter of the thread bounded by the pushing surface and the trailing surface. A volume of the channel decreases in a plurality of revolutions of the thread in a direction from the feed end to the discharge end. A channel depth between the pushing surface and the trailing surface decreases for a first portion of the channel toward the feed end and increases for a second portion of the channel toward the discharge end. At least one of the channel portions has a constant width and includes varying width sub-channels.
