History of large Steel Casting dates back to thousands of years ago，Initially bees wax was used to form the desired pattern and then covered in clay. Coal firs were used to melt the metal which was mostly used to form shapes such as idols, jewelry, and art. As technology advanced the precision of metals and its processes yielded extremely predictable results. Dentists were actually some of the first users of investment casting on a more industrial level, using it to create fillings and false teeth.

　　Advancements in the pattern making, wax, refractories, and melting equipment have resulted in processes that can hold extremely tight dimensional properties. Modern investment castings generally hold dimensions that are measured by a few thousandths of an inch per inch. This allows components to be made that often can be used directly from the manufacturer without subsequent machining. Worst cases allow the parts to be near net shape, which minimizes the amount of handling and processing to be completed on the casting. Users of these casting processes can also deploy the process to create parts that can be poured in thousands of different materials including steel, non-ferrous materials, duplex alloys, aluminum, iron, and more.

　　Investment large steel casting applications have grown tremendously during modern times. The process is used today to create material handling, pumps and valves, transportation, components in aerospace, mine machinery processing and more. Sculptures and original art also use investment casting to create a metal version of the artistic creation. Investment casting may also be used to create medical implements and components used inside the human body.
