When a pulverized material resin material including a pulverized material as at least a part is plasticized and injection-molded by rotating a screw inserted in a heating tube, before use of the pulverized material, the area of a particle shape of the pulverized material in one direction is measured, a pulverized material shape index indicating the relative size of the area with respect to the depth of a screw groove is determined by computation processing, and when the size of the pulverized material shape index is equal to or greater than a preset setting value, the screw is determined to be inappropriate, and at least the result of the determination is displayed.

A method for manufacturing an injection molded container includes operating an injection molding apparatus to inject one or more polymeric materials into a mold cavity to form a container. The container includes an energy director ring protruding from an inside surface of the container and extending circumferentially along the inside surface. The method includes welding a filter onto the inside surface by applying a welding force to the inside surface. The energy director ring causes the welding force to be concentrated at a location of the energy director ring, thereby forming a circumferential weld that secures the filter to the inside surface the location of the energy director ring.

A method of determining a physical relationship between at least one setting parameter of a production cycle of a cyclically operating shaping machine and at least one selected process or quality parameter of the production cycle of the shaping machine, wherein a predetermined variation of a numerical value of the at least one setting parameter is effected in a sequence of production cycles, preferably from one production cycle to another, i and that for each production cycle of the sequence of production cycles the at least one selected process or quality parameter is determined, and that a check is made of the extent to which the at least one selected process or quality parameter has been influenced by the predetermined variation of the numerical value of the at least one setting parameter.

A device for assisting molding condition determination is used with a molding method that molds an article by feeding molten material into a mold. The device includes a learning model generating unit, an input unit, and an output unit. The learning model generating unit creates a learning model through machine learning in which a plurality of molding condition element items used to mold the article and a plurality of quality element items of the molded article are used as learning data. The learning model relates to a degree of influence of each molding condition element item on each quality element item. The input unit receives input of a subject quality element item to be checked, selected from the quality element items. The output unit outputs, using the learning model, the multiple molding condition element item that has the degree of influence on the subject quality element item.
