Investment Casting has been used as early as 1,800 B.C. to produce beautiful bronze works of art. Yet this method of casting fine ferrous and non-ferrous components is even more useful today than in the ancient times. It can still do so many things so much better than many alternatives.
The process involves a number of intricate steps resulting in components which feature considerable design flexibility and economy. The method competes to some degree with machining, forging, die casting and other processes, but is the only means which combines many of the benefits into one. It can, for example, produce a part which previously required several steps, several parts, and was not as strong nor as cost efficient as the investment casting. The net shapes made possible frequently require only minimal finishing.
