Foundry sand (also known as Casting Sand) consists primarily of clean, uniformly sized, high-quality silica sand that is bonded to form moulds for ferrous (iron and steel) and nonferrous (copper, aluminium, brass) metal castings. The most common casting process used in the foundry industry is the sand cast system.
The manufacturing process of cast iron is also named cast iron casting. There are several casting methods used to make cast iron, each with its own advantages and disadvantages. Here are some of the most common casting methods used for cast iron: Sand casting: Sand casting is the most common method for making cast iron. It involves creating a ...
