A state determination device acquires data on an industrial machine, extracts data used for processing related to machine learning from the acquired data, out of the acquired data, according to an extraction condition for extracting the data, and executes the processing related to the machine learning using the extracted data.

An insert molding includes a lithium-ion battery, temperature measurement element and a pressure measurement element disposed close to the lithium-ion battery to sense temperature and pressure around the lithium-ion battery during insert molding; and a molding resin that covers the lithium-ion battery, the temperature measurement element, the pressure measurement element and a cover member.

A state determination device is capable of assisting maintenance for various injection molding machines. The state determination device acquires data related to an injection molding machine, performs numeric conversion for extracting a feature in a temporal direction or an amplitude direction, with respect to time-series data of physical quantity in the acquired data, and performs machine learning using the data obtained through numeric conversion so as to generate a learning model.

A method of detecting and compensating for a non-operational mold cavity in an injection molding apparatus having a plurality of mold cavities and an injection molding screw or ram includes injecting, via the injection molding screw or ram, a molten thermoplastic material into the plurality of mold cavities. The method includes measuring a first process parameter of the injection molding apparatus at a pre-determined time during or after the injecting. The method also includes determining, based on the first process parameter, whether one or more mold cavities of the plurality of mold cavities are non-operational. Then, when it is determined that one or more mold cavities are non-operational, the method includes automatically adjusting the first process parameter or a second process parameter of the injection molding apparatus.

The molding machine includes a cylinder, a screw built in the cylinder, and a state detection device. The state detection device includes a sensor for detecting a state of the screw. The state detection device is attached to the screw outside the cylinder.

A method employing a corrector busing including measuring plastic parts produced by a plastic injection mold, adjusting one or more corrector bushings based on any measured errors in the plastic parts, performing a test production run of plastic parts, measuring the parts produced by the test production run, and determining whether the plastic parts produced by the test production run are within tolerance.

An injection molding management system includes: an identification information acquisition unit acquiring molded product identification information for identifying a molded product; a defect category acquisition unit acquiring, when the molded product is equivalent to a defective product, first defect category information representing a category of a defect of the molded product and second defect category information representing a category of a defect that is different from the first defect category information of the molded product; and a storage unit storing the first defect category information and the second defect category information in association with the molded product identification information of the molded product.

Systems and approaches for controlling an injection molding machine and a mold forming a mold cavity and being controlled according to an injection cycle. The systems and methods include analyzing a model of at least one of the injection molding machine, the mold, and a molten material to determine initial values for one or more control parameters of the injection molding machine, and executing a run of injection cycles at the injection molding machine; measuring operation of the injection molding machine during a particular injection cycle of the run of injection cycles; determining one or more operational parameters exceed a threshold; and upon determining that the one or more operational parameters exceed the threshold, adjusting the one or more control parameters for subsequent injection cycles of the run of injection cycles.

Disclosed is a method of adjusting a motion profile of a shooting pot plunger for use in a molding system, the shooting pot plunger slidably movable within a shooting pot cavity, the method comprising: sensing a characteristic at a predetermined location in an injection circuit of the molding system; determining that the sensed characteristic is outside of a threshold range; adjusting the motion profile of the shooting pot plunger to account for determining that the sensed characteristic is outside of the threshold range; and storing the adjusted motion profile in a memory.

A method for inspecting a molded article, the method enabling non-destructive inspection of an internal condition of a molded article containing fluorine, and a method for producing a molded article including the inspection method. The method for inspecting a molded article includes a step (A1) of inspecting an internal condition of a molded article having a fluorine content of 30% by mass or more based on image data obtained by imaging the molded article by optical coherence tomography.
