Gravity casting is used to make large parts (typically with iron, bronze, brass or aluminum). Most foundry casting processes, including sand casting and permanent molds, can be modeled with FLOW-3D Cast.
Though less violent in its filling process than high pressure die casting, quality can be affected by entrainment of air from overly-turbulent filling, by shrinkage-induced defects and more. The movement of the metal front, as well as location of potential defects and the evolution of temperatures, during filling is accurately predicted. After the filling is complete, the solidification of the metal, and its resulting shrinkage, can also be modeled.
