Abstract

This article introduces filling and feeding concepts from the general perspective of what constitutes good casting practice. It briefly reviews concepts that may help 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. The naturally pressurized filling system is characterized by the narrowness of its flow channels. The article 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. It also lists key features of the naturally pressurized filling system.
