China OEM tloaelo vacuum lahla moralo lisebelisoa matlo a alloy tšepe.
Vacuum Casting e boetse e bitsoa Negative Pressure Tial Casting, Fokotsa Khatello ea Khatello kapa V Process Casting. Vacuum khatello ea ho lahla ho hloka tšebeliso ea lisebelisoa tsa ho ntša moea ho ntša moea ka hare ho hlobo ea ho lahla, ebe o sebelisa phapang ea khatello pakeng tsa ka hare le ka ntle ho hlobo ho koahela filimi e futhumetseng ea polasetiki holim'a paterone le thempleite. Sebōpeho sa ho lahla se tla ba matla ka ho lekaneng ho mamella tšepe e qhibilihisitsoeng nakong ea ho etsa. Ka mor'a ho fumana hlobo ea vacuum, tlatsa lebokose la lehlabathe ka lehlabathe le omeletseng ntle le se tlamella, 'me u tiise bokaholimo ba hlobo ea lehlabathe ka filimi ea polasetiki, e lateloe ke vacuum ho tiisa lehlabathe. Ka mor'a moo, tlosa hlobo, beha li-cores tsa lehlabathe, koala hlobo ho etsa hore ntho e 'ngoe le e' ngoe e loketse ho tšolloa. Qetellong, ho lahla ho fumanoa ka mor'a hore tšepe e qhibilihisitsoeng e pholile ebe e tiisa.
Melemo ea Ts'ebetso ea Vacuum Casting
1) Li-vacuum castings li na le ho nepahala ha maemo a holimo, kemiso e hlakileng le bokaholimo bo boreleli.
Hobane bokaholimo ba mohlala bo koahetsoe ka filimi ea polasetiki, ha ho hlokahale hore u thothomele kapa u kokote ha u hula hlobo. Khatello e hohelang le e mpe e etsa hore lehlabathe le bopehang le kopane, 'me ho thatafala ha hlobo ea lehlabathe ho phahame ebile ho tšoana. Tlas'a mocheso oa tšepe e qhibilihisitsoeng, sekoti ha se bonolo ho holofala. Ho feta moo, ho ba teng ha khatello e mpe ho loketse ho tlatsa ka ho feletseng tšepe e qhibilihisitsoeng ka har'a mohlala. The roughness holim'a V tshebetso castings ka fihla Ra = 25 ~ 2.5μm. Boemo ba mamello ea li-castings bo ka fihla ho CT5 ~ CT7. Ponahalo ea boleng ba likhatello tse mpe tsa khatello e ntle, 'me boleng ba ka hare bo ka tšeptjoa.
2) Ha ho na li-binders, metsi le li-additives ka lehlabatheng la ho bōptjoa, e leng se etsang hore ts'ebetso ea lehlabathe e be bonolo.
3) Ho bonolo ho hloekisa li-vacuum castings. Likhase tse fokolang tse kotsi li hlahisoa nakong ea ho lahla.
4) Li-vacuum castings li ka sebelisoa liindastering tse fapaneng. E ka sebelisoa bakeng sa tlhahiso ea li-batch tse nyane tsa karolo e le 'ngoe hammoho le tlhahiso ea bongata, haholo-holo li-castings tse kholo le tse mahareng le li-castings tse nang le marako a tšesaane li loketse haholo bakeng sa vacuum casting.
