Methods and systems of delivering liquid additives in a molding system are provided. A charging sensor is provided to monitor the status of the injection charging mechanism of the molding system which charges, meters or doses an injection volume of molding material. A dosing instruction is generated based on the charging status signal. The additive pump controls the delivering of the liquid additives into the injection unit based on the dosing instruction, while the injection charging mechanism is charging the injection volume of molding material.

With respect to a controller of an injection molding machine, the injection molding machine includes an injection member provided inside a cylinder to heat a molding material and an injection drive source to fill the molding material into a mold device by moving the injection member forward. The controller includes a limiting part that limits a movement of the injection member forward in a pressure-holding process of controlling an injection drive source so that an actual value of a filling pressure acting on the molding material from the injection member becomes a set value, and a determining part that determines an appropriateness of a setting to be used by the limiting part based on information of a sensor provided in the mold device.

In an injection molding machine of the present invention formed to have a plurality of injection apparatuses connected via a communication channel, a first injection apparatus among the plurality of injection apparatuses includes a display apparatus, a first control apparatus included in the first injection apparatus includes an operation screen input/output unit which obtains operation screen data from another injection apparatus and a rendering attribute converting unit which converts rendering attributes of rendering elements configuring an operation screen to be rendered based on the operation screen data. When an operation screen of the other injection apparatus is displayed on the display apparatus based on the operation screen data, the rendering attribute converting unit makes all or part of the rendering attributes of the rendering elements configuring the operation screen different from rendering attributes when an operation screen of the first injection apparatus is displayed. Thus, the operation screens of the plurality of the injection apparatuses are easily distinguishable.

An injection molding machine uses a native controller and a retrofit controller to effectively control its operation. The controllers may determine and/or receive information regarding the machine's maximum load capacity, and may also determine a current operational load value of the machine. The retrofit controller may cause the machine to operate at any number of combinations of settings of operational parameters which result in the machine operating at or below the maximum load value by adjusting any number of machine parameters associated with the injection molding machine based on feedback sensors measuring real-time operating conditions of the machine.

An abnormality detection device includes a servo CPU; a physical quantity detection unit which detects a physical quantity such as a load applied on a servo motor which operates a movable part included in an injection molding machine. The abnormality detection device further includes a first storage unit directly readable/writable by the servo CPU; and a second storage unit not directly readable/writable by the servo CPU. A reference physical quantity is stored in the first and second storage units. The servo CPU outputs an instruction for stopping or decelerating the movable part in response to a first physical quantity deviation, which is a deviation between a reference physical quantity read from the first storage unit and a current physical quantity, or a second physical quantity deviation, which is a deviation between a reference physical quantity read from the second storage unit and a current physical quantity, exceeds a threshold value.
