An additive feeder system is presented which is operable for use in a plastic injection molding machine including an injection component and a clamping component. The additive feeder system includes a feeder control unit, a feeder supply mechanism and feeder dosage control mechanism. The additive feeder system is operable to provide a specific dosage of the additive materiel in real-time for mixing with the raw material to achieve desired product characteristics. The additive feeder system may be applied to injection molding and extrusion, such as molding processes, plastic molding processes, blow molding, compression molding, extrusion molding, injection molding and laminating, and comprising additive feeders, for example for color mixing and nutrient supplements.

An injection molding condition generation system improves the quality of injection molding. The injection molding condition generation system acquires a material property value of a resin material and an injection molding condition using the first resin material based on a target value of a quality parameter related to a quality of a molded article, the first material property value, and a predetermined relational expression. The predetermined relational expression indicates a relation among the material property value of the resin material, a plurality of injection molding conditions input to an injection molding machine, and a quality parameter related to the quality of the molded article molded by the injection molding machine based on the material property value and the injection molding conditions, and is generated based on data accumulated in the memory in association with the material property value of the resin material, the injection molding conditions, and the quality parameter.

An injection molding system includes a plurality of inspection apparatuses for inspecting molded article quality, a unit that transports a molded article molded by an injection molding machine, a molded article containment unit that is provided for each of types of post-treatment operations needed for the molded article, a transport destination designation unit that selects and designates the molded article containment unit to contain the molded article on the basis of a combination of inspection results from the plurality of inspection apparatuses, and a molded article sorting and transport unit that sorts and transports the molded article into the molded article containment unit designated by the transport destination designation unit.
