Step by step... First a pattern must be made from the original design. The bell is drawn as a finished piece, then a profile of the bell is developed. The profile drawing is then transferred to a template which is used as a sweep. Rotating the sweep around setting plaster creates a pattern which can be used as a die to make other pattern copies.

Shooting. In the shooting process a blow head filled with sand is pressurized with air, leading to the fluidization of the sand which results in a "fluid" consisting of an air/sand/binder mixture. This fluid flows from the blow head through shooting nozzles into the core box, repelling the air out of the box through venting nozzles.
