Manufacturing Process of Cast Iron Castings

Casting is the process of pouring the iron into a mold thus giving it a shape. Molds and pouring methods divide this process up. Molds can be made as expendable molds (sand) or non-expendable molds (metal). Pouring can happen via gravity, low-pressure or vacuum. Controlling the pouring process becomes more important the more intricate the mold is.
