摘要： The invention relates to a process for the production of articles, exemplarily a plastic article, by means of an extruder (1) to which a first plastic composition of a first main component and at least one associated minor component is supplied from a first group of dosing stations (21, 24). According to the invention, during the production time of a first production order there is prepared a second group of dosing stations (31, 33) at the extruder for a second production order for which a second plastic composition of a second main component and at least one associated minor component that is different from the first plastic composition has to be supplied to the extruder. After completion of the first production order it is reset to the second production order by terminating the supply of the first plastic composition by closing a first shut-off device (8) and starting the supply of the second plastic composition by opening a second shut-off device (8′).

摘要： Presented is a process to purge film extrusion systems with at least one extruder (A, B, C, D) for the purpose of changing batches, wherein the speed is changed periodically in at least that part of the extruder, wherein the material is changed. By considering the mass flow rate of the film extrusion system, advantageous improvements of the process avoid the situation in which the film tears off. To this end, at least one selected guide extruder (A) is operated at a speed, which is increased as compared to the normal operation, and at least one selected downstream extruder (B, C, D) is operated at a speed that is decreased as compared to the normal operation. Furthermore, control and operating units (1) and extrusion systems to carry out the process, which include, among other things, means for an automated program run of the purging program and the optical display of the parameters of the same, are presented. The described purging processes result in the production of films having a specific cross section.

摘要： The present invention discloses a biaxial or tri-axial eccentric rotor volume pulsed deformation plasticizing method and device. The method is characterized in that: the conveying volume of materials formed between two or three engaged eccentric rotors, which are formed by spiral structures and eccentric cylindrical structures connected alternately, and an inner surface of a stator changes periodically along the axial direction and the radial direction of the rotors, achieving the volume pulsed deformation plasticizing and conveying of the materials during engaged rotation of the two or three engaged eccentric rotors. The device's eccentric rotors are all formed by length-varying spiral structures and eccentric cylindrical structures connected alternately; the spiral structures of the eccentric rotors are engaged to each other; the axial positions of eccentric cylindrical structures of the two or three rotors are the same. The present invention can implement extrusion of polymer materials or implement, in combination with a plunger injection unit, injection molding of polymer materials, and have many features such as desirable mixing and plasticizing effects for materials, a short thermo-mechanical course, low power consumption, and wide adaptability.

摘要： A kneading apparatus includes a plurality of rotatable discs mounted on a screw shaft disposed on a hollow cylinder and a plurality of fixed doughnut members mounted on an inner wall of the hollow cylinder. The rotatable discs and fixed doughnut members are arranged alternately in an extending direction of the screw shaft. Projected portions and recessed portions extending radially and alternately arranged in a circumferential direction are formed on opposing side faces of the rotatable disc and fixed doughnut members in such a manner that the depths thereof are increased in proportion to the distance from a center of the screw shaft. Accordingly, the kneading apparatus is allowed to have a small construction and yet capable of efficiently kneading the material. In addition, material is prevented from remaining locally in the apparatus, and thereby a proper shear force is applied to the entire material.
