An apparatus for the manufacture and unloading of preforms for the manufacture of plastic containers includes a device for the injection molding of preforms and a device for the cooling and extraction of the preforms from the molding device, and further includes a device for the selective extraction of a predetermined subset of preforms supported by the unloading plate in an orderly manner along at least one pickup direction. The apparatus also includes a component for the orderly transfer of the predetermined subset of preforms to a control and inspection device adapted to perform at least one control on the predetermined subset of preforms.

An injection molding system includes: an injection molding machine configured to inject a molten material into a mold to mold a molded object; a tray moving unit configured to move a plurality of trays in a work area including a placement position; and a robot configured to place the molded object on a tray moved to the placement position among the plurality of trays. The tray moving unit moves a tray after placement, which is a tray on which the molded object is placed by the robot, from the placement position to a position different from the placement position in the work area, and moves a tray before the placement, which is a tray on which the molded object is not yet placed by the robot, from a position different from the placement position in the work area to the placement position.

Systems and approaches for determining design of experiment parameters using largest empty area rectangle optimization for an injection molding system. The systems and methods include obtaining pressure versus time data sets indicative of fill step pressures and corresponding fill step times for a plurality of mold cycles and defining a low and high pressure versus time curves from the data sets, with the low and high pressure versus time curves being two surfaces of a geometric shape. The systems and methods further include identifying a top surface and a bottom surface of the geometric shape; identifying a rectangle having the largest area of all rectangles contained within the first geometric shape; and generating design of experiment parameters from the largest area rectangle.

Provided is an injection molding machine management system that includes an injection molding machine and manages one or a plurality of injection molding units that produce a molded article. The injection molding machine management system includes a display unit configured to display a display screen on which operation information on an operation status of the injection molding unit and at least one of container shortage information on a shortage of a container that accommodates the molded article and material shortage information on a shortage of a material for molding the molded article are displayed on an injection molding unit basis. The container shortage information is displayed on the display screen in association with the operation information when the container is insufficient in the injection molding unit, and the material shortage information is displayed on the display screen in association with the operation information when the material is insufficient in the injection molding unit.
