This article introduces filling and feeding concepts from the general perspective of what constitutes a good casting practice. It briefly reviews the concepts that may help to clarify and quantify objectives for more effective mold-filling designs. The article describes the preprimed filling system through various partial solutions to the prepriming approach. It discusses the six individual parts of the naturally pressurized filling system, namely, offset stepped pouring basin, sprue, sprue/runner junction, runner, gates, and feeding via feeders. The article also lists the key features of the system.
