The New Rheocasting process will provide excellent mechanical properties with a positive solution for the cost of material that has been the weakness of the semi-solid casting process. The process is a kind of batch system. It uses a cup for each shot and a conventional automatic ladling system, which pours molten metal into the cup. This process produces semi-liquid slurry including globular crystals directly from molten metal without a stirring technique. The products made by this process have shown good mechanical properties. The solidification rate of a rheocasting sample is so high that the microstructures of the products are uniform and fine.
