The invention pertains to an apparatus and method of injection molding. This apparatus includes a mold (20) defining a mold cavity (54) and an inlet through which material can pass. Also included is at least one feeder (10) for preparing a broken material. This feeder has an outlet through which material can pass. There is also at least one accumulator (14) spaced from the feeder and the mold. This accumulator has an inlet through which molten material can enter, and an outlet through which molten material can pass. The accumulator also is designed such that it can introduce a molten material through its outlet into the mold cavity and exert a shear stress, compressive force or stress tensor on the molten material contained within the accumulator and/or within the mold cavity. The apparatus also includes a flow control mechanism (28) designed to prevent the flow of molten material from the accumulator back into the feeder.
