    摘要: According to embodiments, there is provided a method (300) of controlling a first melt accumulator (121). The first melt accumulator (121) is part of an injection unit (100), the injection unit (100) including an extruder (102) for preparing molding material and a second melt accumulator (123). The first melt accumulator (121) and the second melt accumulator (123) are configured to sequentially receive molding material from the extruder (102). The extruder (102) is being operable to produce molding material in at least near continuous manner, both the first melt accumulator (121) and the second melt accumulator (123) being associated with a respective shot size set-point. The method comprises detecting (310) an indication of an out-of-boundary condition associated with operation the first melt accumulator (121); responsive to said detecting (310), controlling (320) the first melt accumulator (121) to continue accepting molding material beyond its respective shot size set-point.

    摘要: In an injection molding method, using a heating cylinder having on the front end thereof a discharge nozzle, a single axis screw is rotatable inside the heating cylinder, a fiber-supplying device fills reinforcing fiber into the heating cylinder, and injection molding is performed while supplying the reinforcing fiber and the resin starting material separately and supplying the reinforcing fiber on the front side of the resin starting material. The method includes a plasticization process for obtaining a specified amount of a kneaded product by retracting the screw while rotating in the normal direction to melt the resin starting material and knead reinforcing fiber into the melted resin starting material, and an injection process for discharging the kneaded product from the discharge nozzle by advancing the screw. Reinforcing fiber is supplied into the heating cylinder in the injection process.
