The vacuum flashes off the moisture within the sand mold mixture thereby drying the sand mold mixture to create a solidified sand mold.

The tool is used to process sand molds or sand cores.

The treated sand then is reused to form a foundry sand mold and/or sand core for reduced emissions.

A method of drying a sand mold mixture containing moisture includes restraining the sand mold mixture and exposing the sand mold mixture to a vacuum.

Used molding sand is supplied from a sand supply chute (14A) to a rotor (16).

The inventive sand body is abrasive.

In the sand mold manufacturing step, the evaporative pattern is covered by sand and a sand mold is fabricated without the assembled evaporative pattern being moved from the work plane.

By using the sand mold, aluminum is cast.

A digital representation of a sand core is created.
