Die casting ke eng
Die casting ke ts'ebetso ea ho lahla tšepe e khetholloang ka tšebeliso ea sekoti sa hlobo ho kenya khatello e phahameng ho tšepe e qhibilihisitsoeng.Hangata hlobo e etsoa ka lialloi tse matla, e leng mokhoa o batlang o tšoana le oa ente.Bongata ba li-die castings ha li na tšepe, tse kang zinki, koporo, aluminium, magnesium, lead, tin, le li-alloys tsa lead-tin le li-alloys tsa tsona.Ho ipapisitsoe le mofuta oa ho lahlela lefu, mochini o batang oa mochini oa ho lahla kapa mochini o chesang oa kamore e chesang oa hlokahala.
Die casting e loketse ka ho khetheha bakeng sa ho etsoa ha palo e kholo ea li-castings tse nyenyane le tse mahareng, kahoo ho lahlela lefu ke mokhoa o sebelisoang ka ho fetisisa oa mekhoa e sa tšoaneng ea ho lahla.Ha ho bapisoa le mekhoa e meng ea ho lahla, "die casting" e na le sebaka se bataletseng le ho lumellana ho phahameng.
Ho sebetsa joang ka lefu
Ka mantsoe a bonolo, tšepe die casting e sebetsa ka ho sebelisa khatello e phahameng ho qobella tšepe e qhibilihisitsoeng ka sekoting sa hlobo, se entsoeng ka litšepe tse peli tse thata.Hang ha sekoti se tlatsitsoe, tšepe e qhibilihisitsoeng ea pholile ebe e tiea, 'me e shoa e buleha e le hore likarolo li ka ntšoa.Leha ho le joalo, ts'ebetsong, ho na le mehato e mengata ts'ebetsong, 'me baenjiniere ba nang le tsebo ba hlokeha ho sebelisa lisebelisoa tsa ho lahla.
Mona re tla arola mokhoa oa ho lahlela lefu ka mekhahlelo e meraro:
1. Ho etsa hlobo
2. Ho Lahlela (Filling-Injection-Cavity Ejection- Shakeout)
3. Post-machining
Khamphani ea Star Machining Technology e fana ka litšebeletso tse felletseng tsa Die-Cast tharollo.Matla a rona a kenyelletsa bokhoni ba ho etsa moralo oa lefu le ho etsa lintho ka har'a sehlopha sa litsebi tsa boenjiniere, ho qhibiliha le ho kopanya ka tlung, ho lahla, ho qeta, ho sebetsa ka mechine le ho kopanya.
Bokhoni ba rona ba ho etsa tlhahiso bo re lumella ho hlahisa, ho qeta le lisebelisoa tsa mochini oa aluminium die cast ho kopana le mefuta e mengata ea litlhaloso tsa bareki.Ho tloha ho meralo e bonolo ho isa ho e rarahaneng e sebelisang li-alloys tse 380, 384 le B-390.Boitseanape ba rona le boiphihlelo ba rona bo re thusa ho fana ka mamello e haufi, li-angles tse fokolang tsa moralo, pheletso e ntle le matla a phahameng ka botenya bo fokolang ba lebota bo hlokahalang, ka theko e tlase.

Die Casting Applications
Die casting ke ts'ebetso e matla, e feto-fetohang e loketseng likarolo tse fapaneng, ho tloha ho likarolo tsa enjine ho isa matlong a elektroniki.Mabaka a ho feto-fetoha ha mefuta-futa ea "die casting" a kenyelletsa sebaka sa eona se seholo sa moaho, mefuta e mengata ea likhetho, le bokhoni ba ho etsa likarolo tse qaqileng, tse phetoang, tse nang le marako a masesaane.
Tsa makoloi: Aluminium die casting e tumme indastering ea likoloi kaha e khona ho hlahisa likarolo tse bobebe joalo ka lisilindara tsa hydraulic, li-brackets tsa enjine le mekotla ea li-gearbox.Zinc die casting e loketse mafura, mariki le likarolo tsa ho tsamaisa matla, ha magnesium die casting e sebetsa bakeng sa liphanele le liforeimi tsa setulo.
Sepakapaka: Joalo ka indastering ea likoloi, bafani ba likarolo tsa sefofane ba sebelisa aluminium die casting ho etsa likarolo tse bobebe tse bonts'ang mocheso o phahameng le ho hanyetsa ho bola.Likarolo tse bobebe li fokotsa tšebeliso ea mafura.
Matla: Likarolo tse lahlelang lefu lekaleng la oli le khase li kenyelletsa li-valve, likarolo tsa filtration, le li-impellers.Likarolo tsa matla a ka nchafatsoang joalo ka li-blade tsa turbine tsa moea le tsona li ka etsoa.
Tsa elektroniki: Die casting e atile ho lisebelisoa tsa elektronike, kaha e sebelisoa bakeng sa lintho tse kang liphaello, matlo le lihokelo.Likarolo tsa ho lahla li ka boela tsa etsoa ka lisinki tsa mocheso tse kenyelletsoeng, tse hlokahalang bakeng sa lisebelisoa tse ngata.Magnesium die casting e tumme bakeng sa likarolo tse sireletsang tsa RFI EMI tse tšesaane, ha aluminium die casting bakeng sa likarolo tsa leseli la LED e atile.(Die casting bakeng sa matlo a LED hangata a sebelisa motsoako o kang A383.)
Kaho: Indasteri ea kaho e sebelisa aluminium die casting bakeng sa meaho e meholo joalo ka liforeimi tsa moaho le lifensetere.
Boenjiniere: Lisebelisoa tsa ho phahamisa, lisebelisoa tsa mochini le lisebelisoa tse ling hangata li na le likarolo tsa die cast.
Bongaka: Ho tsa bophelo bo botle, die casting e ka sebelisoa bakeng sa ho beha leihlo likarolo tsa sesebelisoa, lisebelisoa tsa ultrasound le lintho tse ling.
Lisebelisoa tsa Aluminium Die casting
Aluminium ke e 'ngoe ea litšepe tse ka sehloohong tsa ho lahla, 'me lisebelisoa tsa aluminium li sebelisoa ka kamoreng e batang.Li-alloys tsena hangata li na le silicon, koporo le magnesium.
Li-alloys tsa aluminium die casting li bobebe 'me li fana ka botsitso bo botle ba mahlakore, e leng se etsang hore e be khetho e ntle bakeng sa likarolo tse rarahaneng, tse nang le likarolo tse ntle.Melemo e meng ea ho lahla aluminium e kenyelletsa ho hanyetsa kutu e ntle, ho hanyetsa mocheso, le mocheso le motlakase.
Li-alloys tse tloaelehileng tsa die casting aluminium li kenyelletsa:
380: Motsoako oa aluminium oa sepheo se akaretsang o lekanyang bokhoni le thepa e ntle ea mochini.E sebelisoa mefuteng e mengata e fapaneng ea lihlahisoa, ho kenyeletsoa masakaneng a enjine, thepa ea ka tlung, likabelo tsa lisebelisoa tsa elektroniki, liforeimi, lihato, mekotla ea li-gearbox le lisebelisoa tsa motlakase.
390: Alloy e nang le khanyetso e ntle ea ho apara le ho hanyetsa ho sisinyeha.E ntlafalitse ka ho khetheha bakeng sa "die casting" ea li-block tsa enjine ea likoloi hape e loketse 'mele ea li-valve, li-impellers le matlo a pompo.
413: Motsoako oa aluminium o nang le thepa e ntle ea ho lahla.E na le khatello e ntle ea khatello 'me ka hona e sebelisetsoa lihlahisoa tse kang hydraulic cylinders, hammoho le likarolo tsa meralo le lisebelisoa tsa indasteri ea lijo le lebese.
443: The ductile ka ho fetisisa ea die casting aluminium alloys, motsoako ona o loketse thepa ea bareki, haholo-holo e hlokang deformation ea polasetiki ka mor'a ho lahla.
518: Alloy aluminium ea ductile e nang le khanyetso e ntle ea kutu.E sebelisoa lihlahisoa tse fapaneng, ho kenyeletsoa lisebelisoa tsa lisebelisoa tsa sefofane, lisebelisoa tsa mekhabiso, le likarolo tsa escalator.
