摘要： The invention relates to an extruder with which material is extruded through a tool (2). Fluoropolymer is used between the extrusion material and the tool (2) for reducing friction between the material and the tool. At least the surface of the tool (2) against fluoropolymer is of a material whose thermal conductivity is greater than the thermal conductivity of ordinary tool steel. Therefore the friction heat generated can be conducted efficiently away from the interface between the tool (2) and the extrusion material towards the tool (2), whereby the wear of fluoropolymer can be reduced and thus the durability of the tool (2) can be improved. In that case the extrusion product will slip evenly out from the tool (2), whereby the surface of the product is essentially smooth without transverse microscopic stripes repeated at a specific wave length.

摘要： The invention relates to a method and an apparatus for manufacturing an extruded plastic product, the apparatus comprising at least one rotor (1) and at least one stator (2, 3) with a feed gap (4) provided between them, a groove (7) being situated on the other side of the feed gap (4), the groove pressing the material to be extruded out of the apparatus when the rotor (1) is rotated. The cross section of the groove (7) remains substantially unchanged. At the opposite side of the feed gap (4) there is positioned a countergroove (8) in such a way that a processing cavity consisting of the grooves (7), the countergrooves (8) and the clearance between them decreases at least partially continuously along the axis of the extruder. The deformation energy of the material can thus be kept as small as possible due to the unchanging cross section of the groove (7), and the material stays in the groove (7) due to the placement of the flights (7a, 8a). The material is made to move rotatably, which enables the manufacture of a laminar plastic product (11). Further, materials that would otherwise be difficult to process can also be extruded effectively.
