2006 - Dynamics of the Restricted Feed Tree

0.00

This paper is a study of the dynamics that take place during the casting cycle of trees built with a thin primary feed system as first demonstrated by Jurgen Maerz. The paper will show the pattern of the fill process and will analyze the influences of pressure, centrifugal force, rotational deflection and gravity during casting. Further, it will be shown why this system is better for quality, surface finish and fine complex form filling than a conventional tree build style. The outcome of this research has resulted in a technique whereby counter gravity of platinum is achieved in a horizontal centrifugal casting machine.
