Art and jewelry castings have been done more or less successfully for well over 5,000 years. To this day, the seemingly simple technique of casting metal has kept its mysteries and degree of difficulty. The reason for this is a number of variables and sometimes unattended parameters. One of these important parameters is the flow characteristic of the metal as it enters the mold through the gating system. How does the flow of metal influence a good casting? How can it be modified? These questions, the answers and the systematic exploration of these influence parameters will be the topic of this paper.
