    摘要: A method for controlling an injection molding machine comprising a reciprocating plasticizing screw and a controller system adapted for measuring or calculating at least one first production parameter and for controlling/setting at least one second production parameter on the injection molding machine. The method comprises setting a preselected target value for the first production parameter, and inputting the target value into the controller system. The method comprises comparing the measured first production parameter of one production cycle with the preselected target value for the first production parameter. The method comprises calculating by the controller system a new value for the second production parameter as a function of the difference between the first production parameter and the preselected target value for the selected actual production parameter. The method comprises setting by the controller system said new value for the second production parameter for a subsequent production cycle.

    摘要: A method for controlling temperatures in hot runners of a multi-cavity injection mold, a warning method, and a control system based on those methods are provided, in which a temperature sensor is positioned at the same location as each of the cavities of the mold, one of the cavities is chosen as a standard cavity, and a standard filling time is defined. Besides, in every injection cycle, a calculating and controlling module is to calculate the differences between the standard filling time and the filling times of the cavities, and according to the differences, the temperatures in the hot runners may be adjusted by a temperature-adjusting device and a warning device may be started. So, the volumetric filling of the cavities can be balanced very quickly, the process can avoid fluctuations of external environment so as to reduce the time for product development, and the quality of production can be maintained.

    摘要: The retraction of the screw is controlled on the basis of the pressure deviation between the set resin pressure and the detected resin pressure. Furthermore, the screw is caused to rotate at a set speed. Moreover, when the deviation between the metering completion position and the current screw retraction position drops to a value that is equal to or less than a set value, control of the retraction of the screw based on the pressure deviation is stopped, and the control is switched to positioning control based on the positional deviation. Furthermore, a screw rotational speed command in which the pressure deviation component between the set resin pressure and the current resin pressure is corrected from the screw rotational speed component that is decelerated in proportion to the positional deviation is determined and output.
