Gravity pouring is still the dominant process for the production of cast steel materials. The principle is simple and has remained basically unchanged for several centuries. However: To comply with filigree and complex component geometries as well as increasing quality demands, the process-related limitations lead to significant challenges for foundry staff and foundry engineers. Consequently, achieving the target geometry is only possible by using large quantities of liquid material with, in some cases, simultaneously high rejection rates. Consequent alternative is low-pressure pouring, which requires much smaller sprue cups and feeder system than gravity pouring.
