Abstract
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.
