A preform optical inspection system includes a plurality of carrier units, each mounted on a respective lane conveyor for receiving preforms from an injection molding device and an optical inspection unit. The optical inspection unit is able to transverse movement across the lane conveyors and the carrier units are able to pass though the optical inspection unit.

A method and a device for detecting a geometric feature of consistent molded parts takes into account the different stages of cooling due to different durations of transport of the individual removed molded parts to the inspection system. Both the geometric feature and the temperature of each molded part is measured. The detected geometric features are corrected using a calibration function taking into account the measured temperatures.

A method for manufacturing a molded part while changing between multiple molds including a first ejecting step of opening a first mold and ejecting the molded part from the first mold, a checking step of checking the ejected molded part to determine if the molded part is acceptable, a first injecting step of closing the first mold and performing injection into the first mold, a second ejecting step of, where the ejected molded part is determined to be acceptable, changing the first mold to a second mold and ejecting the molded part from the second mold after the first injecting step, and a third ejecting step of, in a case where the molded part ejected in the first ejecting step is determined to be non-acceptable, not changing the first mold to the second mold and ejecting the molded part from the first mold.

A molding machine management system includes: a molding machine configured to mold a molded product using a molding mold having a plurality of cavities; a camera configured to capture an image of the molded product molded by the molding machine; an inspection device configured to inspect the molded product; and a management server including a control unit configured to acquire the image captured by the camera and an inspection result by the inspection device and cause a display unit to display the image and the inspection result. The management server includes a storage unit configured to store the image of the molded product, the inspection result of the molded product, and information on a cavity in which the molded product is molded in association with each other, and the control unit causes the image of the molded product molded by the molding machine, the inspection result of the molded product, and the information on the cavity in which the molded product is molded to be displayed on a same screen of the display unit.

A production management system includes: an injection molding unit producing a molded product; and a control device. The injection molding unit includes: an injection molding machine molding the molded product by injection molding; a determination unit determining whether a number of the molded products to be produced is equivalent to a predetermined unit of production or not; and an operation information transmitting unit transmitting operation information of the injection molding unit when it is determined that the number of the molded products to be produced is equivalent to the predetermined unit of production. The control device includes an operation information receiving unit receiving the operation information transmitted from the operation information transmitting unit.

An injection molding machine management system includes an injection molding machine, a first detecting section configured to detect at least one of a physical quantity of the injection molding machine and a physical quantity of a molded article, an on-premise server, and a Cloud server. The Cloud server includes a first storing section configured to store information concerning at least one of the physical quantity of the injection molding machine and the physical quantity of the molded article detected by the first detecting section and a virtual machine configured to generate a control rule for the injection molding machine based on the information. The on-premise server includes a second storing section configured to store the control rule and a control section configured to perform, based on the control rule, control of the injection molding machine corresponding to at least one of the physical quantity of the injection molding machine and the physical quantity of the molded article detected by the first detecting section.

There is provided an injection molding machine management system including an injection molding machine configured to mold a molded article with injection molding, a peripheral device configured to perform a post-process of the injection molding, and a control device communicably coupled to the injection molding machine and the peripheral device. The injection molding machine management system includes a generating section configured to generate a common identifier for each of predetermined production units and transmit the common identifier to the peripheral device. Molding data concerning the injection molding and post-process data concerning the post-process are correlated with the common identifier.

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 system (10) and method of use where the system (10) is comprised of an injection molding system (10), a controller (16) for controlling pack or fill pressures of the injection fluid injected during the pack and fill phases, a recorder, the controller including instructions that controls drive of actuators (1a, 2a, 3a, 4a) to effect an increase or decrease in fill and pack pressures of the injection fluid.

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.
