Alloy steel foam castings ke lihlahisoa tsa tšepe tse lahliloeng ke mokhoa o lahlehileng oa ho lahlela foam. Lost Foam Casting (LFC), eo hape e bitsoang Full Mold Casting, ke mofuta oa ts'ebetso ea ho etsa tšepe e nang le ts'ebetso ea ho lahla lehlabathe le omeletseng. Ka linako tse ling EPC e ka ba khutsufatso bakeng sa Expendable Pattern Casting hobane mekhoa ea foam e lahlehileng e ka sebelisoa hang feela. Ka mor'a hore mekhoa ea foam e phethoe ka mechine e khethehileng, joale lipaterone tsa polasetiki tse foamed li koahetsoe ka ho roala ha refractory ho etsa khetla e matla ho mamella tšepe e qhibilihisitsoeng. Mekhoa ea foam e nang le likhetla e kenngoa ka har'a lebokose la lehlabathe, 'me u le tlatse ka lehlabathe le omeletseng ho pota-pota. Nakong ea ho tšeloa, tšepe e qhibilihisitsoeng e nang le mocheso o phahameng o etsa hore mohlala oa foam o be pyrolyzed 'me o "nyamela"' me o nke sebaka sa ho tsoa sa mekhoa, 'me qetellong ho fumanoa li-castings tse lakatsehang.
