摘要： A screw includes a screw main body, a conveyance portion conveying a raw material, and a passage provided in the screw main body. The passage includes a first passage element, a second passage element, and a third passage element. The screw main body has a plurality of cylindrical bodies arranged in an axial direction of the rotating shaft. At least a portion of the conveyance portion is formed on outer peripheral surfaces of the cylindrical bodies adjacent to each other, and the passage is formed in the cylindrical body so as to cross over between the adjacent cylindrical bodies.

摘要： A method and a device for admixing additives into a polymer melt made of non-extracted polyamide 6 are disclosed. The polymer melt is combined in a highly concentrated form with an additional melt flow without additives and mixed therewith. Additionally, a part of the melt is branched off from a main melt flow (3), wherein the sub-melt flow (4) is transported into a dispersing device (5) and is supplied and mixed with one or more additives (12). The side-melt flow (4) with additives is then returned into the main melt flow (3), mixed with the main melt flow, and subsequently supplied for further processing.

摘要： A screw machine includes an inductive heating device for the processing of material to be processed. The inductive heating device is used to heat the material in a heating zone. In the heating zone, at least one housing portion is made of an electromagnetically transparent material at least partly, the material being non-magnetic and electrically non-conductive, whereas at least one treatment element shaft is made of an electrically conductive material at least partly. During the processing of the material, the inductive heating device generates an alternating magnetic field that produces eddy current losses in the at least one treatment element shaft, the eddy current losses leading to a temperature increase of the at least one treatment element shaft. The material is heated on the at least one heated treatment element shaft, in particular until it melts. The screw machine allows a simple and efficient melting of the material, with the result that a mechanical energy input and a resulting wear of the screw machine can be reduced significantly.

摘要： A kneading apparatus includes a processor, and a extruder. The extruder includes a screw. The screw includes a screw main body. A conveyance portion, a barrier portion, and a path are provided at places of the screw main body. In at least one of the places, the path is provided inside the screw main body, and includes an entrance and an exit. The raw materials, pressure on which is increased by the barrier portion, flow in from the entrance. The raw materials flowing in from the entrance flow through the path toward the exit. The exit is positioned to be remote from the entrance in an axial direction.

摘要： Exemplary embodiments are disclosed of systems and methods for dispensing thermal management and/or EMI mitigation materials. The system and methods include online remixing prior to dispensing the thermal management and/or EMI mitigation materials. In an exemplary embodiment, a system includes an online remixer configured to be operable for receiving a supply of the thermal management and/or EMI mitigation material including one or more functional fillers within the matrix, and remixing the one or more functional fillers including filler settlement, if any, within the matrix prior to dispensement of the thermal management and/or EMI mitigation. The remixing may reduce the filler settlement, if any, within the matrix and thereby allow for improved viscosity and flow rate of the thermal management and/or EMI mitigation material.
