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 hloekisavacuum 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.
