Abstract
A low-pressure casting apparatus includes a core that together with a mold forms a cavity and a reduced-pressure dryer configured to dry the core under reduced pressure. The core is disposed in the mold, the molded is closed, the core is dried under reduced pressure, and thereafter the cavity is filled with molten metal.
