Abstract

The core sand is removed from castings after the cast metal has hardened by mounting the casting on a rapping table and by applying the stamper of a compressed hammer to a wall with an impact energy to create cracks in the core. The casting is then transferred to a vibrating table where it is shaken until the core is broken up and the sand also runs out of the core holes.
