1- Ho lahla lephaka ke eng?
Lephaka lahla le boetse le tsejoa e le Negative Khatello tiisitsoe lahla, fokotswa Khatello lahla kapa V Process lahla. Lephaka la khatello e mpe ke mofuta o mong oa ho lahla lehlabathe le ommeng mme ho hloka ts'ebeliso ea lisebelisoa tsa ho ntša moea ho hula moea kahare ho hlobo, ebe o sebelisa phapang ea khatello lipakeng tsa kahare le kantle ho hlobo ho koahela filimi e futhumetseng ea polasetiki ho dipaterone le dithempleite. Hlobo ea ho betla e tla ba matla ho lekana ho mamella tšepe e qhibilihisitsoeng nakong ea ho betloa. Kamora ho fumana hlobo e lahletsoeng, tlatsa lebokose la lehlabathe ka lehlabathe le ommeng ntle le binder, ebe o tiisa bokaholimo ba hlobo ea lehlabathe ka filimi ea polasetiki, e lateloe ke lephaka ho tiisa lehlabathe hore le tiee. Kamora moo, tlosa hlobo, beha li-cores tsa lehlabathe, koala hlobo ho etsa hore ntho e ngoe le e ngoe e lokele ho tšoloha. Qetellong, ho lahla ho fumanoa kamora hore tšepe e qhibilihisitsoeng e pholile le ho tiea.
2- Melemo ea ho lahla lephaka ke efe?
1) The castings lephaka na phahameng tlhakore ho nepahala, hlakile kemiso le holim boreleli.
2) Ha ho na binders, metsi le additives ka lehlabathe bōpa, e leng se etsang lehlabathe sebetsa bonolo.
3) Ho bonolo ho hloekisa castings lephaka. Ho hlahisoa likhase tse seng kotsi haholo nakong ea ts'ebetso.
4) The castings lephaka ka sebelisoa ka e mengata e fapaneng liindasteri. E ka sebelisoa bakeng sa tlhahiso e le 'ngoe ea li-batch tse nyane hammoho le tlhahiso ea bongata, haholo-holo li-castings tse kholo le tse mahareng le li-castings tse nang le mabota a masesaane li loketse ho lahla lephaka.
3- Lisebelisoa tsa tšepe le lits'epe tse kopantsoeng li ka lahleloa joang?
• Gray Cast Tšepe, Ductile Cast Tšepe
• Carbon Steel: Carbon e tlase, k'habone e mahareng le tšepe e phahameng ea khabone
• Lisebelisoa tsa Steel Cast: Lisebelisoa tse tlaase tsa alloy, tšepe e phahameng ea alloy, tšepe e khethehileng ea alloy
• Aluminium le lits'epe tse kopantsoeng le tsona
• Koporo le Koporo.
4- Ke Liindasteri Life Tse Sebelisitsoeng ka Lephephe?
Joalokaha ho boletsoe ka holimo ka melemo ea ho betsa lephaka, le castings lephaka ka sebelisoa ka e mengata e fapaneng liindasteri. E ka sebelisoa bakeng sa tlhahiso e le 'ngoe ea li-batch tse nyane hammoho le tlhahiso ea bongata, haholo-holo li-castings tse kholo le tse mahareng le li-castings tse nang le mabota a masesaane li loketse ho lahla lephaka. Ka hona, li-castings tse hloekisang li sebelisoa haholo bakeng sa mechini ea temo, litsamaiso tsa haeteroliki, likoloi tsa thepa ea seporo, likhohlo le indasteri ea kaho ea likepe.
5- Ke Mathata afe a ho lahla a ka fihlelloang ke ts'ebetso ea ho lahla?
Nakong ea ho betsa lephaka, hobane bokaholimo ba mofuta bo koahetsoe ka filimi ea polasetiki, ha ho na lebaka la ho thothomela kapa ho kokota ha o hula hlobo. Ts'ebetso le khatello e mpe li etsa hore lehlabathe le bōpehe, 'me boima ba hlobo ea lehlabathe bo phahameng ebile bo tšoana. Tlas'a mocheso oa tšepe e qhibilihisitsoeng, mokoti ha o bonolo ho holofala. Ho feta moo, boteng ba khatello e mpe bo thusa ho tlatsa ka botlalo tšepe e qhibilihisitsoeng. Boreleli ba holim'a metsi ba V bo ka fihla Ra = 25 ~ 2.5μm. Boemo ba mamello ea tlhakore ea castings bo ka fihla ho CT5 ~ CT7. Boleng ba ponahalo ea khatello e mpe ea khatello bo botle, 'me boleng ba kahare boa tšepahala.
