Cast alloy steel v process castings e bolela likarolo tsa ho lahla tse hlahisoang kemokhoa oa ho ntša vacuume nang le lisebelisoa tse entsoeng ka tšepe ea alloy.
Vacuum molding casting, e boetse e bitsoa mokhoa o mobe oa ho bopa khatello, mokhoa oa ho tiisa ka vacuum, kapa ts'ebetso ea V ka nako e khuts'oane. Ona ke mofuta o mocha oa mokhoa oa ho etsa mohlala oa 'mele. Mokhoa o mobe oa ho bopa khatello o sebelisa phapang ea khatello pakeng tsa ka hare le ka ntle ho hlobo ho tiisa likaroloana tsa lehlabathe tse omeletseng le tse hlephileng hammoho ho fumana hlobo e nang le sebōpeho se itseng se lakatsehang le matla a itseng.Lisebelisoa tsa tšepe li ka aroloa ka tšepe ea tšepe e entsoeng ka tšepe le tšepe ea carbon ho ea ka sebopeho sa eona sa lik'hemik'hale, 'me e ka boela ea aroloa ka tšepe ea tšepe e entsoeng ka tšepe, tšepe e khethehileng, ea boenjiniere le ea mohaho le tšepe ea alloy ho latela litšobotsi tsa eona. Tšepe ea alloy e ka aroloa ka tšepe e tlase ea alloy (kakaretso ea likarolo tsa alloy e ka tlase ho kapa e lekana le 5%), tšepe ea alloy e entsoeng (kakaretso ea likarolo tsa alloy ke 5% ho isa ho 10%) le tšepe e phahameng ea alloy (kakaretso ea alloy). likarolo li kholo ho feta kapa li lekana 10%). Lisebelisoa tsa lehlabathe la alloy tse sa keneleng ho roala ke likarolo tsa ho lahla tse hlahisoang ke ts'ebetso ea lehlabathe e entsoeng ka tšepe e sa sebetseng ea alloy. Ho RMC Foundry, lits'ebetso tsa mantlha tsa ho lahla lehlabathe tseo re ka li sebelisang bakeng sa tšepe e sa sebetseng ea alloy ke ho lahla lehlabathe le letala, ho lahla lehlabathe le koahetsoeng ka lehlabathe, ho lahla hlobo ea lehlabathe le sa bakeng, ho lahlela foam, vacuum casting le ho etsa matsete. Phekolo ea mocheso, kalafo ea holim'a metsi le mochini oa CNC li fumaneha hape fekthering ea rona ho latela litšoantšo le litlhoko tsa hau.
Vacuum casting e lumella ho etsoa ha lihlopha tse nyane tsa libopa tsa boleng bo holimo ka har'a mefuta e mengata ea li-polyurethane resin tse phetang ts'ebetso ea lipolasetiki tsa boenjiniere ntle le litšenyehelo tse phahameng tsa lisebelisoa tse thata tse amanang le ho bopa ente. Ts'ebetso e qala ka ho etsa hlobo ka ho kenyelletsa mohlala o motle ka har'a rabara ea silicone e nang le likarolo tse peli. Ebe ho sebelisoa vacuum ho tlosa moea leha e le ofe o qabeletsoeng, ebe o phekoloa ka ontong. Mehlala e hloahloa e ka tsoa ho mefuta e mengata ea theknoloji ea khatiso ea 3D ho kenyelletsa le stereolithography. Hang ha silicone e phekoloa, hlobo e khaoloa e butsoe ho theha mohala o arohaneng, ho tlosoa mohlala o moholo o sieang sekoti sa hlobo se pheta-pheta hantle mohlala oa master. Ho etsa karolo, likarolo tsa hlobo li khutlisetsoa hammoho, li sirelelitsoe, li futhumalitsoe pele 'me li behoa ka kamoreng ea tsamaiso ea vacuum casting. Likarolo tse peli kapa tse tharo tsa resin li lekanngoa, 'mala o kenngoa ha ho hlokahala' me likarolo tsa resin li kenngoa ka har'a motsoako o ikemetseng oa sistimi ea vacuum casting. Mothating ona, sistimi ea vacuum casting e nka ts'ebetso ea ho kopanya likarolo tsa resin le vacuum cast ea mohlala. Hang ha sena se phethiloe, semela se hloekisoa. Ka mor'a ho phekola, likarolo tsa hlobo li ka aroloa 'me karolo e tlosoa. Ho setseng ke bakeng saho lahla likaroloho pongoa le ho phethoa kamoo ho hlokahalang.
