A system and a method for monitoring states of an injection molding machine includes a data collector, a controller, and an alarm apparatus. The data collector communicates with a molding equipment, a mold, and a mold temperature controller. Data of the molding equipment, data of the mold, and data of the mold temperature controller is constantly collected in real time by the data collector. The controller determines whether the data comprises a value exceeding a predetermined value range. The alarm is activated if the data is determined to comprises a value exceeding the predetermined value ranges.

A remote controller can be provided on any apparatus that employs feedback control from a native controller to add functionality to the apparatus where the native controller is not capable of providing such functionality independently.

When the deceleration start point is reached, the meter-in side of the hydraulic driving actuator is subjected to a flow rate control to thereby start the deceleration control processing. The position to which the movable unit is moved is detected to use a speed instruction corresponding to the movement position to subject the hydraulic driving actuator to a meter-in control. The position to which the movable unit is moved is detected to calculate the moving speed of the movable unit. Based on the speed instruction, the moving speed is subjected to the feedback control using the meter-out control to the hydraulic driving actuator.

A time variation of an internal pressure of the molding cavity of a multi-phase injection molding machine is detected and represented as an internal pressure graph. An internal pressure graph recorded during a production cycle that produced an injection molded part satisfying a predefined quality characteristic is used as a reference graph. If the internal pressure graph of the current production cycle exceeds a predefined threshold value, then a current machine parameter is changed so as to adapt an internal pressure graph of a subsequent production cycle to the reference graph. Each phase of the production cycle is assigned its own machine parameter determined to have a significant impact on the quality of the parts produced. The assigned machine parameters are changed in a predefined order in a plurality of production cycles wherein exactly one assigned machine parameter is changed per production cycle.
