The invention pertains to an apparatus and method of using the same. This apparatus includes a mold defining a mold cavity and an inlet through which molten material can pass. Also included is at least one feeder for preparing a molten material. This feeder has an outlet through which molten material can pass. There is also at least one accumulator 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 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 is designed to prevent the flow of molten material from the accumulator back into the feeder. Also included is a device for controlling and monitoring the temperature of any molten, material contained within the accumulator and/or within the mold.
