OEM zinc alloy die casting
Zinc die casting ke ts'ebetso e sebetsang hantle haholo ea tlhahiso e atisang ho sebelisoa ho theha likarolo tsa tšepe tse rarahaneng ka nepo le ho tšoarella ho makatsang. Ho fapana le mekhoa e meng ea tlhahiso, die casting e lumella tlhahiso e kholo ea likarolo tse nang le lijeometri tse rarahaneng, lintlha tse ntle, le liphetho tse ntle tsa bokaholimo, kaofela ha li ntse li boloka mamello e tiileng.
Sengoliloeng sena, re hlahloba ts'ebetso ea "zinc die casting" le ho hlahloba melemo ea mantlha ea ho sebelisa li-alloys tsa zinki ha ho etsoa "die casting", ho kenyelletsa le ho feto-fetoha ha moralo oa likarolo, ho boloka litšenyehelo, le ts'ebetso e phahameng ea mochini.
Zinc Die Casting ke eng?
Ha ho etsoa die casting, li-alloys tsa zinki lia qhibiliha ebe li kenngoa ka har'a hlobo ea tšepe tlas'a khatello e phahameng. Mokhoa ona o lumella tšepe e qhibilihisitsoeng ho tlatsa libopeho tse rarahaneng tsa hlobo ka potlako le ka nepo.Sebaka se tlase sa ho qhibiliha ha zinc(e ka bang 387-390 ° C) e etsa hore e be e loketseng bakeng sa sena. Ka mor'a ho pholile, tšepe e nka sebōpeho se nepahetseng sa hlobo, e fokotsa tlhokahalo ea ts'ebetso e eketsehileng.
Hobaneng o Khetha Zinc bakeng sa ho Lahlela?
Molemo oa Zinc die casting ke hore zinki e na le metsi a mangata ha e qhibiliha, ho bolelang hore e ka etsa libopeho tse rarahaneng ka ho nepahala. Ea eonamatla le ts'ebetso ea ho hanyetsae boetse e na le likarolo tse ikhethang.
Ho fapana le litšepe tse ling, zinki e boloka botšepehi ba eona ka nako. Theko ea zinki e batla e le tlase, 'me e eketsa boipiletso ba eona bakeng sa tlhahiso. Ho feta moo, e lumella lipotoloho tse potlakileng tsa tlhahiso hobane e pholile ebile e thatafala kapele.
Ts'ebetso ea "Zinc Die Casting" ke eng?
Mohato oa pele oa ts'ebetso o kenyelletsa ho rala le ho theha lesela, leo hangata le entsoeng ka tšepe ea boemo bo holimo. Lefu ha e le hantle ke hlobo e mpe ea karolo e lokelang ho lahleloa. Pele ho etsoa ntho leha e le efe, hlobo e tšeloa, e thusang ho tlosa karolo e phethiloeng habonolo le ho lelefatsa bophelo ba hlobo.
Joale, alloy ea zinki kapa zinki e qhibiliha ka sebōping ka mocheso o batlang o le tlaase. Zinc e qhibilihisitsoeng e kenngoa ka har'a sekoti ka khatello e phahameng haholo ho sebelisoa kamore e batang kapa mochine o chesang oa kamoreng ea ho chesa.
Mokhoa ona oa khatello e phahameng o tiisa hore zinki e qhibilihisitsoeng e tlatsa esita le sekoti se senyenyane ka ho fetisisa 'me e hlahisa likarolo tse rarahaneng, tse qaqileng tse nang le botsitso bo botle ba likarolo.
Hang ha e kentsoe, zinki e qhibilihisitsoeng e pholile kapele ebe e tiea ka har'a lesoba. Ka lebaka la sebaka sa eona se tlase sa ho qhibiliha, zinki e tiea kapele ho feta litšepe tse ling tse ngata, ho bolelang hore likaroloana li ka ntšoa ho tloha ka metsotsoana e 15 ho isa metsotsong e seng mekae ho latela boholo ba tsona le ho rarahana ha tsona.
Ka mor'a hore tšepe e tiee 'me e fihlele matla a lekaneng a mochine, lefu lea buloa,' me karolo e ntšoa ka li-ejector pins. Karolo (eo hape e tsejoang e le "casting") e boloka sebopeho se nepahetseng sa lefu.
Ho ipapisitsoe le litlhoko tsa sehlahisoa sa ho qetela, bokaholimo bo ka kenyelletsa ho belisoa, ho phatloha ho hoholo, ho penta, kapa ho sebelisa litlolo tse sireletsang, joalo ka electroplating (mohlala, chrome, nickel).

Lipotso Tse Botsoang Hangata
Zinc e bapisoa joang le aluminium die casting mabapi le ho tšoarella le litšenyehelo?
Mefuta ea zinc e nka nako e telele ho feta ea aluminium ka lebaka la ho hanyetsa ha eona hantle. Sena se etsa hore e be khetho e tšoarellang haholoanyane tlhahisong. Mabapi le litšenyehelo, li-alloys tsa aluminium kapa aluminium li bobebe 'me li ka ba theko e tlaase bakeng sa likarolo tse kholoanyane, empa zinki e ka ba chelete e ngata bakeng sa likaroloana tse nyenyane, tse qaqileng ka lebaka la ho nepahala le matla a eona.
A na u ka hlalosa phapang pakeng tsa zinki le tšepe e sa hloekang bakeng sa lisebelisoa tsa ho lahla?
Zinc e bonolo ebile e bonolo haholoanyane, e lumellang hore ho be le libopeho tse rarahaneng le meralo. Tšepe e sa hloekang, le hoja e le matla haholo, e thata ho lahla 'me e sebelisoa haholo-holo bakeng sa lihlahisoa tse hlokang matla a eketsehileng le ho hanyetsa. Zinc e boetse e theko e tlase ebile e betere bakeng sa ho theha likarolo tse ngata tse nang le lintlha tse ntle.
Ke lintlha life tsa bohlokoa tse lokelang ho nahanoa ha u khetha mochini oa ho lahla zinki?
Batla mechini e fanang ka taolo e nepahetseng holim'a mocheso le khatello ho netefatsa hore li-castings tsa boleng bo holimo.
