| Nano-composite structures are formed by pre-loading carbon nanotubes (CNTs) into at least one of a plurality of channels running the length of a cartridge, placing the pre-loaded cartridge in a piston chamber of a die-casting machine, creating a vacuum therein, and filing the piston chamber with molten metal to soak the pre-loaded cartridge and fill empty cartridge channels. Pressure is applied via the piston to eject the carbon nanotubes and molten metal from the cartridge channels and inject the nano-composite mixture into a rod-shaped die cavity. The internal diameter of the cavity is equal to or less than the final diameter of the nozzle. The nano-composite mixture is cooled to form a solid nano-composite rod having the first predetermined diameter, wherein the carbon nanotubes are aligned in a non-random manner. Furthermore, drawing down the nano-composite rod to smaller diameter wire further disperses the nanotubes along the length of the wire. | ||||||

| An apparatus for processing molten material into a desired shape comprises a die or mold forming a cavity to receive molten material and to allow its solidification within the cavity. A source of vacuum is connectable to the cavity for sucking air out. A hollow after-pressure cylinder is in communication with the cavity so as to receive a portion of the material. The after-pressure cylinder has a first end for connection to the cavity, and a second, opposite end. In the region of the second end is a connection opening for connecting the vacuum source. An after-pressure piston is moveable in the after-pressure cylinder to press its portion of material into the cavity to compensate for any shrinkage of the material in the cavity. There is a drive for moving the after-pressure piston in its after-pressure cylinder into three different positions, i.e.: (a) in a first position, the after-pressure piston is in the region of the cylinder's second end, leaving the connection opening in communication with the cavity, (b) in the second position, the after-pressure piston has moved over the connection opening to interrupt the communication with the cavity, and (c) in a third position, said after-pressure piston has moved from said second position towards said cavity to press said portion of material into it. | ||||||
