    • Axial extruder contains a rotary placed conical head (2), which alongside the conical end (1) of the screw (4) creates a tapering space (23) between the cones. The conical end (1) of the screw (4) can have a system of the alternately arranged axial transversal grooves (24, 25) and the inner surface of the rotating conical head (2) can have the system of the alternately arranged axial transversal grooves (24, 25, 26). The rotating conical head (2) with the outer teeth is placed at the end of the casing (9) of the screw (4) with the bearing (7) in the bearing housing (8) of the head. By means of a gear (12) a motor (10) for driving the head (2) is connected to the outer teeth of the conical head (2). The frequency and direction of the rotation of the head (2) is independent on the frequency and direction of the rotation of the screw (4). The conical end (1) of the screw (4) and the inner surface of the head (2) can have different conicity. The conical end (1) of the screw (4) is separated from the inner front of the head (2) by distance (L).
    • 轴向挤出机包括旋转放置的锥形头部(2),其与螺钉(4)的锥形端部(1)一起在锥体之间形成锥形空间(23)。 螺钉(4)的锥形端(1)可以具有交替布置的轴向横向槽(24,25)的系统,并且旋转锥形头部(2)的内表面可以具有交替布置的轴向横向 凹槽(24,25,26)。 具有外齿的旋转锥形头(2)被放置在螺钉(4)的壳体(9)的端部,轴承(7)位于头部的轴承壳体(8)中。 通过齿轮(12),用于驱动头部(2)的马达(10)连接到锥形头部(2)的外齿。 头部(2)的旋转的频率和方向与螺杆(4)的旋转的频率和方向无关。 螺钉(4)的锥形端(1)和头部(2)的内表面可以具有不同的锥度。 螺钉(4)的锥形端部(1)从头部(2)的内部前部离开距离(L)。

    • The invention provides systems, methods, and articles useful in the production of foams, and, in particular microcellular foams. The systems include a restriction element that reduces the backflow of polymer melt in an extruder while polymeric material is injected into a mold or ejected from a die. The restriction element is positioned upstream of a blowing agent injection port to maintain the solution of polymer and blowing agent in the extruder above a minimum pressure throughout an injection or ejection cycle, and preferably above the critical pressure required for the maintenance of a single-phase solution of polymer and blowing agent. The systems can be used in injection molding, blow molding, or in any other processing techniques that include injection or ejection cycles. In some embodiments, the systems utilize reciprocating screws for injection or ejection. In other embodiments, the systems include an accumulator connected to an outlet of the extruder, in which a plunger moves to inject polymeric material into a mold or eject polymeric material from a die.
    • 本发明提供了可用于生产泡沫,尤其是微孔泡沫的系统,方法和制品。 该系统包括限制元件,其减少聚合物熔体在挤出机中的回流,同时将聚合物材料注入模具或从模具中排出。 限制元件位于发泡剂注入口的上游,以将聚合物和发泡剂在挤出机中的溶液保持在整个喷射或喷射循环中的最低压力之上,并且优选高于保持单相所需的临界压力 聚合物和发泡剂的溶液。 该系统可用于注射成型,吹塑成型或包括注射或喷射循环的任何其它加工技术。 在一些实施例中,系统利用用于注射或排出的往复式螺钉。 在其它实施例中,系统包括连接到挤出机的出口的蓄能器,其中柱塞移动以将聚合物材料注入模具或从模具中排出聚合材料。
