LOST FOAM Lost Foam is a method used to create foam patterns made of expanded polystyrene (EPS) or other gasifiable foam plastics that are lost during the casting process. The high temperature of the liquid metal causes the foam pattern embedded in sand to evaporate just fractions of a second before it meets the melted mass. This makes it possible to produce complex cast parts with drill holes, through holes, oil and cooling channels using bonded segments.
