Alloy simbi yakarasika furo castings ndiyo simbi yekukanda zvigadzirwa zvakakandwa nerakarasika foam casting process. Yakarasika Foam Casting (LFC), inonziwo Yakazara Mold Casting, imhando yesimbi yekugadzira maitiro ane yakaoma jecha kukanda maitiro. Iyo EPC dzimwe nguva inogona kunge ipfupi yeExpendable Pattern Casting nekuti akarasika foam mapatani anogona kushandiswa kamwe chete. Mushure mekunge maitiro efuro apedzwa nemichina yakakosha, ipapo mapatani epurasitiki ane furo anoputirwa nerefractory coating kuti iite goko rakasimba kuti rimire nesimbi yakanyungudutswa. Mafuro maitiro ane makungu anoiswa mubhokisi rejecha, uye rizadze nejecha rakaoma rakaripoteredza. Panguva yekudururwa, simbi yakanyungudutswa yakakwirira-yepamusoro inoita kuti foam pateni ive pyrolyzed uye "inonyangarika" uye inotora nzvimbo yekubuda yemapateni, uye pakupedzisira iyo yakapedzwa inodiwa castings inowanikwa.
