A method for monitoring a molding process carried out in cycles includes determining at least two nearest neighbors in the form of cycle data from at least two past cycles, such that the cycle data of the at least two nearest neighbors lie nearer to the current cycle data than the cycle data which do not pertain to the at least two nearest neighbors. Only those past cycles for which quality data are contained in the data collection are used for the determination of the at least two nearest neighbors. A predictability criterion is checked to determine whether a quality variation of the quality data of the cycles of the at least two nearest neighbors is smaller than a maximum variation and/or larger than a minimum variation. If the predictability criterion is not met, a first notification that a quality and/or a quality datum of the molded part is not reliably predictable is issued.

An injection molding system includes: an injection molding machine configured to operate in accordance with a command generated using a first language, and inject a molten material into a mold to mold a molded object; a robot configured to operate in accordance with a command generated using a second language, and convey the molded object; and a control device configured to control the injection molding machine and the robot. When determining that an error occurs in at least one of the injection molding machine and the robot, the control device transmits, to the injection molding machine, a command generated using the first language and for causing the injection molding machine to execute a return operation, and transmits, to the robot, a command interpretable by the second language and for causing the robot to execute a return operation, so as to cause the injection molding machine and the robot to execute the return operations.

For the purpose of enabling high-accuracy detection as to whether a molded resin product is a non-defective product or a defective product and advance detection of a molded resin product that may suffer deformation or the like in the future, the present invention relates to an inspection method and a manufacturing method for a molded resin product as well as an inspection device and a manufacturing device for a molded resin product, wherein, in an inspection of a joint interface of a molded resin product divided into a plurality of members, the height positions of defect candidates are measured from the results of detecting X rays radiated via at least two paths when the X rays are transmitted through the molded resin product, which makes it possible to detect a defect with high accuracy.

An apparatus (1) for the inspection of parisons (2) comprises: an inspection zone (10), configured to receive an unordered plurality of parisons (2); an illuminator (3), configured to emit a beam of light directed at the plurality of parisons (2); a detector (4) comprising a camera (41) configured to capture an image of the plurality of parisons (2), wherein the inspection zone is interposed between the illuminator (3) and the detector (4); a control unit (5) configured to process the image captured by the camera (41) to derive an item of diagnostic information regarding the defectiveness of one or more parisons (2) of the plurality of parisons (2), wherein the illuminator (3) includes an emission-polarizing filter (32) and the detector (4) includes a receiving polarizing filter (42).

Provided is a method for testing a melt-fabricable fluororesin injection-molded article which enables easy determination of whether or not a tested article is a defective article due to a crack or delamination. The method for testing a melt-fabricable fluororesin injection-molded article includes determining whether or not a melt-fabricable fluororesin injection-molded article is defective due to a crack or delamination based on a stress-strain curve or tensile strength-strain curve obtained by a tensile test performed on the injection-molded article.

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.

An injection molding system for making a molded item freely fall in demolding process from a mold, the injection molding system comprising: a molded item photographing device, an image analysis device, and a molded item classification device, wherein the image analysis device is configured to perform analysis of appearance feature of the molded item, and make the item classification unit classify the molded item based on result of the analysis.

An injection molding system includes: a first extruding member that extrudes a first molded article from a mold; a robot that transfers the first molded article extruded from the mold to an assembling position in relation to a second molded article in the mold; a second extruding member that extrudes the second molded article from the mold towards the first molded article retained at the assembling position by way of the robot, and assembles the second molded article to the first molded article; and a load detection unit that detects load applied to the second extruding member, in which defect discrimination of the first molded article, the second molded article, or an assembled state of the first molded article and the second molded article is performed, based on load detected by the load detection unit when the second molded article is assembled to the first molded article.

A molding system capable of detecting an abnormality for each cavity when a plurality of molded articles is molded at a time by a mold having a plurality of cavities mounted on an injection molding machine is a molding system for detecting an abnormality of a cavity by inspecting a molded article molded by a mold having a plurality of cavities mounted on an injection molding machine. The molding system includes a molded article information acquiring unit for acquiring molded article information indicating a state of the molded article for each cavity over a plurality of molding cycles, and a cavity abnormality detecting unit for detecting an abnormal cavity by mutually comparing tendencies of the molded article information between cavities.
