Aloyi zitsulo zotayidwa thovu castings ndi zitsulo kuponyera zinthu zoponyedwa ndi kutaya thovu kuponya njira. Lost Foam Casting (LFC), yomwe imatchedwanso Full Mold Casting, ndi njira yopangira chitsulo yokhala ndi mchenga wowuma. EPC nthawi zina imakhala yaifupi ya Expendable Pattern Casting chifukwa mawonekedwe a thovu otayika atha kugwiritsidwa ntchito kamodzi kokha. Mapangidwe a thovu akamalizidwa ndi makina apadera, ndiye kuti mapepala apulasitiki opangidwa ndi thovu amakutidwa ndi zokutira zokanira kuti apange chipolopolo cholimba kuti chipirire chitsulo chosungunuka. Mapangidwe a thovu okhala ndi zipolopolo amayikidwa mu bokosi la mchenga, ndikudzaza ndi mchenga wouma kuzungulira iwo. Pakutsanulira, chitsulo chosungunula chotentha kwambiri chimapangitsa chithovu kukhala pyrolyzed ndi "kuchoka" ndipo chimakhala chotuluka pamapangidwewo, ndipo pamapeto pake zomaliza zofunidwa zimapezedwa.
