We have two kinds of investment casting process. One is being used in the world
called Silica Gel process. Its advantage is better surface finish and tight tolerances of dimension. But an disadvantage is higher cost than another investment casting process called sodium silicate process. The later can make castings with not too better surface finish castings than the former process. but It has lower cost than the former. Usually, the later is being used for production of carbon steel, low alloy carbon steel, bronze, ductile iron to lower cost. But Silica gel process also can be used for these castings and also stainless steel castings.
