Lost Foam Casting Process For Metal Molding
The lost foam casting method uses an expanded polystyrene (EPS) foam pattern that is expendable. For each casting that is poured an EPS foam pattern is burned up.
The process starts out by creating a foam tool from which foam pieces are made. The casting design can have undercuts, minimal draft, anything that can be placed into the foam tool. Also, the final foam pattern can be made from several pieces of EPS foam that are glued together allowing design flexibility not possible in other casting processes. If the part is small, a tree of multiple foams can be glued together. This final foam piece will also have a gating system attached to it for pouring.
After the foam is complete, it is coated in a re-fractory wash, placed into a large flask, where dry, loose sand is poured around the foam while the flask is vibrated. The vibration effectively compacts the sand around the foam and helps to fill any difficult to fill areas. The molten metal is poured into the flask instantly vaporizing the foam upon contact and replacing the volume it once occupied. The solidified casting is removed from the flask after cooling and trimmed from its gating system. Lost foam castings exhibit a characteristic surface finish of the expanded beads and very little if any parting line flashing.
