Lost foam casting (eo hape e tsejoang e le mold casting ea 'nete) e entsoe ka polasetiki ea foam (EPS, STMMA kapa EPMMA) polymer material hore e be hlobo ea sebele e nang le sebopeho le boholo bo lekanang hantle le likarolo tse lokelang ho hlahisoa le ho lahleloa, 'me e koahetsoe. e nang le ho roala refractory (e matlafalitsoeng), e boreleli ebile e phefumoloha) 'me e omisitsoe, e patoa ka lehlabathe le omeletseng la quartz' me e behiloe ka mokhoa oa ho thothomela ka likarolo tse tharo. Tšepe e entsoeng ka ho qhibilihisoa e tšeloa ka lebokoseng la lehlabathe le bōpiloeng tlas'a khatello e mpe, e le hore mohlala oa thepa ea polymer o futhumale 'me o be mouoane, ebe o ntšoa. Mokhoa o mocha oa ho lahla o sebelisang tšepe ea metsi ho nka sebaka sa nako e le 'ngoe ea ho lahla hlobo e entsoeng ka mor'a ho pholile le ho tiisa ho hlahisa li-castings. Ho lahleheloa ke foam ho na le litšobotsi tse latelang: 1. Lisebelisoa ke tsa boleng bo botle le theko e tlaase; 2. Lisebelisoa ha li na moeli ebile li loketse boholo bohle; 3. Ho nepahala ho hoholo, bokaholimo bo boreleli, bohloeki bo fokolang, le ho etsa machining ho fokolang; 4. Litšitiso tsa ka hare li fokotsehile haholo 'me sebopeho sa ho lahla se ntlafatsoa. E teteaneng; 5. E ka hlokomela tlhahiso e kholo le ka bongata; 6. E loketse ho lahla lihlahisoa tse ngata tsa li-castings tse tšoanang; 7. E loketse ts'ebetso ea matsoho le tlhahiso ea mohala oa kopano o ikemetseng le taolo ea ts'ebetso; 8. Boemo ba tlhahiso ea mohala oa tlhahiso bo finyella litlhoko tsa litekanyetso tsa tekheniki tsa tšireletso ea tikoloho. ; 9. E ka ntlafatsa haholo tikoloho ea ho sebetsa le maemo a tlhahiso ea mohala oa tlhahiso ea ho lahla, ho fokotsa matla a mosebetsi, le ho fokotsa tšebeliso ea matla.
