Spin Casting
We will attempt to pour the liquid paraffin in a sealed cylindrical mold and spin this between 1000-3000 rpm until the paraffin has solidified and the shrinkage has created the right diameter port in the center of the grain.
The new technique uses the lathe to spin the grain, while molten paraffin is introduced through a hole at one end of the spinning assembly. The end cracking and surface cracking issues we have seen in the past are now resolved. (2005.7)
