Fluidized Sand Bed

The Fluidized Sand Bed is designed to fit your investment casting system and facility needs.

The Fluidized Bed consists of a segmented valved air distribution manifold with a porous segmented bed to support the sand. Vulcan can completely engineer, manufacture, and install shell/foam project or upgrade existing one. Inventory control and real-time shell/foam management appear simple with Vulcan’s state-of-the-art electronic shell/foam management system.
