摘要： A notched region in which the outer periphery of a screw flight is cut out is provided in a molding material feed screw. A wedge-shaped portion is formed by both a front wall surface of the screw flight and a wall surface of the boundary where the outer periphery of the screw flight is cut out. As a result of rotation of the molding material feed screw, since the wedge-shaped portion advances while pushing aside resin pellets located in the front thereof in two lateral directions of the front wall surface of the screw flight and the wall surface of the boundary where the outer diameter of the screw flight is cut out, entrapment of the resin pellets between the edge of a material supply port of a molding material supply device and the outer periphery of the screw flight is avoided as much as possible.

摘要： An extruder screw that enables mixing of viscous materials, such as rubber mixtures and thermoplastic materials, is disclosed. The screw includes a core extending from a sealing end to a nose cone end. At least one flight extends radially from the core in a quasi-helical pattern, wherein flights adjacent one another form channels therebetween. A plurality of elongate lugs extend radially from the core and are disposed in the channels. The shape as well as the number of lugs can be varied to ensure the requirements for a thorough and turbulent deflection and mixing of the material stream.

摘要： The aim of the invention is to provide a plastifying screw provided with a thread change, for an extruder or a forcing machine, whereby the volume of the transporting cross-section does not change and thus a pressure increase in the region of the thread is avoided. To this end, in the region wherein a first and a second screw thread of the plastifying screw overlap, the thread width outside the overlapping region is equal to d and the thread width inside the overlapping region is equal to ½ d.

摘要： A screw element includes an outer radius Ra and a core radius Ri for multiscrew extruders with co-rotating and intermeshing screw shafts. The screw element has in axial cross section through its longitudinal axis a profile which has at each of the two axial end faces (i.e. a front end face and a rear end face) only one screw flight corresponding to a conventional single-start screw element for intermeshing screw shafts. In this case, the width (flight land angle φ) of the screw flight and conversely, in a corresponding way, the width (flight land angle φ) of the screw flight are formed in a special way and a shearing flight with a constant shearing flight radius Rs, which is greater than Ri, and less than Ra, is provided.

The foam extrusion assembly further includes a heat extraction region structured to extract excess heat from the mixture of melted material pellets and blowing agent such that the mixture achieves an extrudable temperature. The heat extraction region includes an elongate barrel having at least one inlet and at least one outlet, the inlet being structured to receive the extrusion mixture therethrough for passage into the barrel wherein a heat extraction structure cooperatively disposed with the barrel draws heat therefrom. An extrusion screw is disposed in the barrel and includes at least one screw flight structured to rotate within the barrel and urge the extrusion mixture towards the outlet of the barrel where a die is disposed in order to form the finished product. Moreover, the screw flight includes at least one circulation channel defined therein and structured to receive quantities of the extrusion mixture therethrough upon rotation of the extrusion screw, thereby circulating the extrusion mixture towards the barrel for more effective and uniform cooling of the extrusion mixture to an extrudable temperature prior to passage through the die.
