Sand Casting
Bronze and aluminum are cast in oil-based sand in the Product Realization Lab. Students in ME203: Manufacturing and Design take part in a structured lab that introduces the sand casting process.
A mold of sand is formed around a pattern to define the desired geometry. After the mold is formed and prepared, a crucible of molten metal is lifted out of the furnace and the metal is poured into the mold. Post-machining and finishing bring the raw casting to a more useful and attractive form.
Patterns are typically made from wood or modulan using various tools in the Woodworking lab, as well through 3D printing. Students in ME318: Computer-aided Product Creation can mill complex pattern geometry in modulan on the CNC mills in the Machining Lab.
