Yes, I am familiar with centrifugal casting machines. The type used most commonly in the model train industry for casting low temp meal is nothing like the one I used years ago.

Now they use silicone molds that will take the heat and the casings are arranged in a disk-like shape and spin continuously on a turntable, then you pour your melt in the center as it spins. Designed for big volume, but has poor quality (IMO), flash and casting lines. Plus low temp metal is $15 to $20 a pound.

The one I used years ago was a jeweler's style. An articulated arm that is wound on a spring, then you set your hot mold in a clamp on the end of the arm and the gold was melted in a crucible a few inches from the mold and once melted, you close the lid and hit the release and the spring would spin the arm with great force. The molten gold would shoot out the crucible and directly into the mold where the force would push it into every void in the mold.

I'm not sure if I need a centrifugal casting machine for this job, but if I need one I will build it myself. Those commercial units cost real big bucks!
