Lost Foam Casting, eo hape e bitsoang Lost Foam Casting (LFC) kapaFull Mold Casting, ke mofuta oa Evaporative Pattern Casting (EPC) e omilengmokhoa oa ho lahla lehlabathe. 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 ke mechine e khethehileng, joale mekhoa ea polasetiki e phofshoang e 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.
2- Mehato ea ho Lahla Foam e Lahlehileng ke Efe
1- Sebelisa hlobo ea foam ho hlahisa lipaterone tsa foam le litsamaiso tsa ho lahla
2- Tlama lipaterone le limathi ho etsa mojule oa mould bundle
3- Kenya pente mojulung
4- Omisa pente
5- Kenya mojule ka har'a lebokose la lehlabathe 'me u le tlatse ka lehlabathe le omileng
6- Ho thothomela ho etsa hore ho tlatse sekoti ka lehlabathe le omileng ebe o kopanya lehlabathe le bopehileng
7- Ho tšela tšepe e qhibilihisitsoeng ho etsa mouoane ebe o etsa li-castings tse lakatsehang
8- Kamora hore li-castings li pholile, hloekisa li-castings. Lehlabathe le omeletseng le ka sebelisoa hape

✔ Ha ho hlokahale hore ho be le li-angle tse hlokahalang ho boloka litšenyehelo tse ngata.
✔ Lipaterone tse kopaneng tsa foam li ka bokelloa ho tsoa likotong tse 'maloa tsa lipaterone tsa foam.
✔Li-foam tse lahliloengke ts'ebetso e haufi-ufi ea sebopeho
✔ Ho feto-fetoha ha maemo ka linako tse khutšoane tsa ho seta
✔ Bophelo ba tšebeletso ea hlobo ea EPS e telele, ka hona, litšenyehelo tsa lisebelisoa li fokotsehile
✔ Litšenyehelo tsa kopano le kalafo li fokotsoa ke ho se be teng ha ts'ebetso ea kalafo, likarolo tsa ho kenya, likhokahano tsa screw, jj.
✔ Katoloso ea boholo ba lits'ebetso
4- Ke Litšepe life le lialloys tse ka Lahloang ke Ts'ebetso e Lahlehileng ea Foam?

5- Ke Liindasteri life tseo The Last Foam Castings li sebelisetsoang tsona?
Joalo ka ha ho boletsoe ka holimo, ho lahla foam e lahlehileng ho loketse ka ho khetheha ho hlahisa li-castings tse kholo le tse teteaneng. Ba sebeletsa haholo mechini e boima e nang le litlhoko tsa sebopeho se rarahaneng sa li-castings tse lakatsehang.
6- Ke Mamello afe a ho Lahlela a ka Finyelloang ke Ts'ebetso ea ho Lahlela Foam e Lahlehileng?
Ka kakaretso, mamello ea ho lahla foam e lahlehileng e molemo ho feta ho lahlela lehlabathe, empa e mpe ho feta ho lahla hlobo ea khetla le mekhoa ea ho lahlela e sa bake. Bakeng sa ronafoam foundry e lahlehileng, ha e le hantle re ka fihlela limaraka tse latelang tsa mamello. Empa re rata ho bua le uena ka libapali tse ikhethileng ebe re etsa qeto ea hore na re ka u fa linomoro life.
