An injection molding system includes a plurality of inspection apparatuses for inspecting molded article quality, a unit that transports a molded article molded by an injection molding machine, a molded article containment unit that is provided for each of types of post-treatment operations needed for the molded article, a transport destination designation unit that selects and designates the molded article containment unit to contain the molded article on the basis of a combination of inspection results from the plurality of inspection apparatuses, and a molded article sorting and transport unit that sorts and transports the molded article into the molded article containment unit designated by the transport destination designation unit.

A system includes a cavity, an injection nozzle configured to inject material into the cavity, and a plurality of sensors at sensor locations. Each of the plurality of sensors is configured to measure parameters at one of the sensor locations. The system lacks a strain gauge. The system further includes a controller configured to control a flow rate of the injection of material into the cavity. The controller is configured to receive the measured parameters and compare the received information to predetermined curves. The controller is configured to control the flow rate when the measured parameters deviate from the predetermined curves.

An apparatus for forming a first component making up at least a part of a housing on a trimmer head and a method of using the apparatus. The housing has a rotary axis and is configured to support at least one radially projecting cutting component. The first component has a central axis. A forming unit defines at least one cavity within which a moldable material is confined to produce at least a part of a wall on the first component that extends around the rotary axis. The forming unit is configured to allow selective controlling of a quantity of a moldable material introduced into a first discrete subvolume at a first location in the one cavity to thereby allow selective controlling of a mass of a portion of the at least part of the wall formed by the moldable material in the one cavity at the first location to facilitate dynamic balancing of the housing, within which the first component is incorporated, with respect to the rotary axis.

An injection molding system includes a molding device, an inspection device configured to inspect a molded product and a control device that includes a storage unit, and a reception unit configured to receive a change content of a parameter included in a standard molding condition. The control device executes a first control of forming the molded product under a second molding condition in which the parameter is changed based on the change content, a second control of forming the molded product under a third molding condition in which the same parameter is changed, a third control of associating the second molding condition with an inspection result of the molded product formed under the second molding condition and storing the association, and a fourth control of associating the third molding condition with the inspection result of the molded product formed under the third molding condition and storing the association.

An injection molding system is provided with inspection means for inspecting an insert part before a resin is injected into a mold, inspection data output means for outputting inspection data on the insert part obtained by the inspection means, and inspection data recording means for recording the inspection data on the insert part and physical quantities related to the injection of the resin into the mold in association with the cycle number of the molded article from the injection molding machine. Thus, the cause of bad molded articles, as well as that for a finished product, can be investigated in consideration of the inspection data on the insert part inserted into the mold.

A stepped flight is formed on a screw of an injection molding machine. The stepped flight is a flight in which a step-shaped step portion is formed on a top portion thereof. The top portion of the flight includes a large diameter portion on an upstream side and a land portion on a downstream side. When a gap ratio m of a gap H.sub.1 between the land portion and a bore of the heating cylinder to a gap H.sub.2 between the large diameter portion and the bore is defined as H.sub.1/H.sub.2, the gap ratio m is selected to be 2.3m6.4.

An artificial intelligence-based injection molding system comprising a standard data extraction unit for extracting target standard data of a product produced by a mold from mold information about the mold to which a molding material is supplied; a molding condition output unit inputting the extracted target standard data into a pre-learned molding condition generation model to output a molding condition; an injection molding device, supplying the molding material to the mold according to the molding condition to produce the product; and a determination unit, comparing production standard data of the produced product and the target standard data to determine whether the molding condition is appropriate, wherein, if the determination unit determines that the molding condition is inappropriate, the molding condition output unit generates the production standard data and the molding condition as one set of feedback data, and trains the molding condition generation model with the set of feedback data.
