Alloy uamea leiloa foam castings o oloa lafo u'amea lafo e leiloa foam faiga lafo. Lost Foam Casting (LFC), e taʻua foʻi o le Full Mold Casting, o se ituaiga o uʻamea faiga faʻagasologa faʻatasi ai ma le faʻamagoina o le oneone. O le EPC e fa'apuupuu i nisi taimi mo le Expendable Pattern Casting ona o mamanu foam ua leiloa e mafai ona fa'aoga tasi. A maeʻa faʻamaʻi foam e faʻamaeʻaina faʻapitoa, ona faʻapipiʻiina lea o mamanu palasitika foamed i le ufiufi faʻafefe e fausia ai se atigi malosi e tatalia ai le uʻamea uʻamea. O fa'ata'ita'iga foam ma atigi e tu'u i totonu o le pusa oneone, ma fa'atumu i oneone mamago o lo'o si'omia ai. I le taimi o le sasaa, o le uʻamea uʻamea maualuga-maualuga e faʻapipiʻiina ai le foam pattern pyrolyzed ma "e mou atu" ma nofoia le avanoa e alu ese ai o mamanu, ma mulimuli ane maua ai le faʻamaeʻaina o mea e manaʻomia.

| Aitema | Ua leiloa Foam Casting | Vacuum Casting |
| Tulaga talafeagai | Laiti ma feololo faʻameamea faʻatasi ma faʻalavelave faʻalavelave, e pei o poloka afi, afi afi | Va'aiga feololo ma lapopo'a e iai ni pu laiti pe leai, e pei o u'amea fa'atatau, fa'amea uamea. |
| Mamanu ma Papatusi | Fua fa'ata'ita'iga e faia e fa'ameamea | Fa'ata'ita'i fa'atasi ma le pusa suction |
| Pusa oneone | La'u po'o le lima itu fa'afefe | E fa itu fa'asuavai po'o fa'atasi ai ma paipa fa'asu |
| Ata Palasitika | O le pito i luga e faʻamaufaʻailogaina i ata palasitika | O itu uma o afa e lua o le pusa oneone ua faʻamaufaʻailogaina i ata palasitika |
| Mea e ufiufi ai | Vali fa'avae vai fa'atasi ma le mafiafia o le ufiufi | O vali e fa'atatau i le 'ava malosi ma le fa'alava manifinifi |
| Suia oneone | oneone matutu malō | oneone mamago lelei |
| Vibration Molding | 3 D Vibration | Vibration Tu'usa'o po'o Fa'asaga |
| Liligi | Liligi Leaga | Liligi Leaga |
| Fa'agasologa oneone | Fa'amama le mamafa le lelei, liliu i luga le pusa e pa'u ai oneone, ona toe fa'aaogaina lea o le oneone | Fa'amama le mamafa le lelei, ona pa'u lea o le oneone mago i totonu o le lau, ma toe fa'aaogaina le oneone |
