ABSTRACT:
Core sand material is received in an enclosed chamber and is forced into the cavity of a mold by compressing the air above the sand material with essentially no mixing of the air and sand material. The air is compressed by a piston which forces a pressure packer plate downwardly above the core sand material which is held in the bottom of the chamber by a specially designed baffle control plate assembly ready to be forced by the compressed air into the mold.
