... to keep the die parting line parallel. In most cases, the faces of the die are flat, and their plane determines the parting line. If this is not done properly, there will be incomplete closure and interference between the die and the casting. This interference can cause the casting to be bent and the tool...

.... Such a pressurized system is intended to force the metal to back up at the ingates and rapidly fill the runner, although complete filling of a cope runner will often depend on at least partial filling of the casting. During this period of incomplete filling, turbulence and the potential for air entrainment and dross...

However, in these castings, martensite is mixed with large amounts of retained austenite, and therefore, hardness levels are lower than can...
