    摘要: Disclosed is a device and method for dynamic extrusion molding of plastic articles having variable micro-channel. The device mainly includes a single-screw extruder, a dynamic extrusion die, a fluid source, a water sink, a tractor, a winding device, and a data acquisition and control system. Near outlet of extrusion die, when the end portion of a syringe needle is at different positions, the inner diameter of the micro-channel of the extrusion molded plastic article is also different. When the hollow syringe core within the dynamic extrusion die performs a high-frequency short-range vibration along an extrusion direction, the inner diameter of the micro-channel of the extruded plastic articles is dynamically variable. The plastic articles of variable micro-channel of the present invention has novel structure with high dimensional accuracy, and a variety of varying patterns, it can be stably produced by simple processing equipment with high level of automation.

    摘要: A method for controlling temperature rise in divided heating zones of a barrel of a molding machine includes: setting tentative target temperatures for the respective heating zones; simultaneously raising temperatures in the heating zones to the set tentative target temperatures; when temperatures in the heating zones reach the respective tentative target temperatures, selecting a master zone from the heating zones, and selecting, as a slave zone, a heating zone which is other than the master zone among the heating zones; and after temperatures in the heating zones reach the respective tentative temperatures, raising the temperatures in the master zone and the slave zone to respective final target temperatures according to an attainment degree of temperature rise in the master zone.
