An information processing system includes: an acquisition unit that acquires waveform data obtained through an operation of control target equipment; an analysis unit that extracts, based on a relationship of variables included in the acquired waveform data, a first variable that is at least a portion of the variables and a second variable that is at least another portion of the variables, that derives variables corresponding to the second variables based on the first variable, and that defines characteristics of the control target equipment based on the derived variables and the second variable; and an output unit that outputs information used in controlling the control target equipment based on the characteristics of the control target equipment.

A virgin material plasticization time Tv, which is a time required for a screw to reach a predetermined plasticization end position Xe when only a virgin material Rv is plasticized, a crushed material plasticization time Ts, which is a time required for the screw to reach the predetermined plasticization end position Xe when only a crushed material Rs is plasticized, are measured and registered as basic time data Do. Actually measured time data Dp are obtained by measuring a crushed material mixed material plasticization time Tm when a molded product is produced by using the crushed material mixed material Rm, the crushed material mixed material plasticization time Tm being a time required for the screw to reach the plasticization end position Xe in a predetermined shot. The crushed material ratio Px in the crushed material mixed material Rm is obtained on the basis of the virgin material plasticization time Tv, the crushed material plasticization time Ts, and the crushed material mixed material plasticization time Tm. An output process is performed on the obtained crushed material ratio Px.

The present disclosure pertains to injection molding methods, tooling, and products. An example injection molding tool that can be used to create both a part with an aperture and a part without an aperture. The injection molding tool has a first portion; a second portion; a first insert installed on the first portion, the insert comprising a protrusion that creates a gap relative to a sidewall of the second portion when the first portion and the second portion are closed to form an injection molding tool; and a material source that flows material into the injection molding tool, the material having a melt flow rate that is below a melt flow rate threshold to create a first part with an aperture due to the presence of the protrusion and the gap, wherein the aperture has no flashing.

Method for the quality control and/or tracking of an injection molded part produced in a production cycle using at least one processing machine of the plastic processing industry and a plastic processing facility, in which production devices or stations arranged upstream or downstream are connected together via a network. Each individual injection molded part or a specified number of injection molded parts is assigned a quality value composed of multiple quality values in that each device or station in the production chain ascertains or generates its own quality value and extends same by the transmitted values of each previous device or previous station and forwards same as the new quality value to the following device or following station or in that a separate collecting station, in particular a hardware and software, requests the quality values, the device values and/or material values thereof, from the individual devices or stations or is transmitted thereto, and the collecting station puts said the values into correlation.

A runner system for a multi-cavity injection molding system, the runner system having runners of reduced size.

In order to injection mold parts at a constant flow front velocity in a mold cavity of an injection molding system, particularly where the mold cavity has a varying thickness along its length, mold modeling software is used to calculate the cross-sectional area as a function of the distance from the gate, percentage of fill, or length of the mold cavity. Based on that cross-sectional area, the mold modeling software determines an appropriate recommended ram force profile and/or melt pressure profile that would result in filling the mold cavity at a constant flow rate. An injection molding system is then operated according to the recommended ram force profile and/or melt pressure profile.

Provided by the present disclosure is an ultrasonic phased array-based in-situ imaging method for melt flow in injection molding. The ultrasonic phased array is used for the detection of an injection molding process for the first time, and an effective dynamic monitoring imaging method for a melt front position is developed. A melt flow process in a mold cavity is dynamically monitored by collecting an FMC (Full matrix capture) dataset online. A mapping relationship between an incident angle and a target pixel point is established to rapidly determine time delay of each point in a measurement target region, and a melt bottom image is acquired using TFM (Total focusing method) imaging conditions, from which the melt front can be localized. The provided method is high in measurement accuracy, short in imaging time, and capable of effectively improving imaging efficiency of online measurement.

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 of producing an iron core product may include: substantially simultaneously putting resin materials into each of a plurality of first accommodating portions formed in a heating portion; substantially simultaneously initiating heating, by the heating portion, of the resin materials disposed in the first accommodating portions; and supplying a molten resin from the first accommodating portions to resin forming regions provided in a core body.
