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.

A control system and a control method of manufacturing injection molding products are provided. The control system includes an injection molding machine, an information input interface, a computing server and a data conversion device. At first, product information is inputted through the information input interface. The product information is transmitted to the computing server, and then the computing server determines injection molding parameters according to the product information. The injection molding parameters are transmitted to the information input interface. After data conversion through the data conversion device, the injection molding machine is controlled to manufacture the injection molding products according to the converted injection molding parameters.

An artificial intelligence-based injection molding system in which molding conditions can be changed to manufacture fair-quality products when defective products are manufactured because of disturbances during the injection molding including an injection molding machine which performs injection molding by injecting a molding material into a mold; an injection state data acquisition unit for acquiring, during injection molding, current injection state data that includes the viscosity profile of the molding material injected into the mold and/or the injection pressure value thereof; a determination unit, which inputs the current injection state data into a molding quality maintenance model trained with predetermined target injection state data, so as to determine whether to maintain molding quality; and a molding condition setting unit for changing a preset molding condition so that the current injection state data follows the target injection state data, when the determination unit determines not to maintain the molding quality.

A method and device is provided for operating an injection molding machine. The method uses the device, which is configured for determining the viscosity index of a melt in a cavity of an injection molding tool. The device includes pressure sensor member that measures an internal mold pressure of the melt in the cavity. The device includes an evaluation member configured for evaluating sensor data generated by the pressure sensor member. The evaluation member is configured to determine the viscosity index of the melt from the evaluated sensor data. The evaluation member is configured to compare the viscosity index to a target viscosity index and accordingly adjust operation of the machine's operating parameters so that the viscosity index of the melt conforms to the target viscosity index indicative of production of an acceptable part by the injection molding machine.

An injection molding machine includes: a clamping device having a fixed mold and a movable mold, configuring a mold, and a clamping force sensor to detect a clamping force of the movable mold to the fixed mold; an injection device having an injection nozzle and a screw to fill the mold with a molten resin via the injection nozzle; and a control device, wherein the control device monitors a variation of the clamping force from the clamping force sensor, causes a slow speed forward movement time at a timing of VP switching to be increased if the variation exceeds a predetermined upper limit, and causes the slow speed forward movement time at the timing of VP switching to be reduced if the variation falls below a predetermined lower limit.
