die casting ke eng?

Die casting ke ts'ebetso ea ho lahla tšepe, e khetholloang ka ho sebelisa khatello e phahameng ho tšepe e qhibilihisitsoeng ho sebelisa sekoti sa hlobo. Hangata hlobo e entsoe ka li-alloys tse matla a holimo, 'me mokhoa ona o batla o tšoana le oa ente. Boholo ba li-die castings ha li na tšepe, joalo ka zinki, koporo, aluminium, magnesium, lead, tin, le li-alloys tsa lead-tin le li-alloys tsa tsona. Ho itšetlehile ka mofuta oa lefu la ho lahla, o hloka ho sebelisa mochine o batang oa kamoreng ea ho lahla kapa mochine o chesang oa ho lahla.

Litsenyehelo tsa lisebelisoa tsa ho lahla le hlobo li phahame, kahoo mokhoa oa ho lahla ka kakaretso o sebelisoa feela bakeng sa tlhahiso ea bongata ba lihlahisoa tse ngata. Ho etsa likarolo tsa die-cast ho batla ho le bonolo, hoo ka kakaretso ho hlokang mehato e mene feela, 'me keketseho ea litšenyehelo e tlase haholo. Die casting e loketse ka ho khetheha bakeng sa ho etsa palo e kholo ea li-castings tse nyane le tse mahareng, kahoo "die casting" ke mofuta o sebelisoang haholo oa mekhoa ea ho lahla. Ha ho bapisoa le litheknoloji tse ling tsa ho lahlela, bokaholimo ba "die-casting" bo bataletse ebile bo na le maemo a holimo.

Ho itšetlehile ka mokhoa oa setso oa ho bolaea, mekhoa e mengata e ntlafetseng e tsoetsoe, ho kenyelletsa le mokhoa o se nang porous oa lefu-casting o fokotsang mefokolo ea ho lahla le ho felisa porosity. E sebelisoa haholo-holo bakeng sa ho sebetsa zinki, e ka fokotsang litšila le ho eketsa chai ea ts'ebetso ea ente e tobileng. Ho boetse ho na le lits'ebetso tse ncha tsa "die-casting" joalo ka theknoloji ea "die-casting" e nepahetseng le "semi-solid die-casting".

Mabapi le hlobo

Litšitiso tse ka sehloohong tse ka hlahang ts'ebetsong ea ho lahla lefu li kenyelletsa ho roala le ho khoholeha. Litšitiso tse ling li kenyelletsa ho phatloha ha mocheso le mokhathala oa mocheso. Ha bokaholimo ba hlobo bo na le mefokolo ka lebaka la phetoho e kholo ea mocheso, ho tla hlaha mapetsong a mocheso. Ka mor'a tšebeliso e ngata haholo, mefokolo e holim'a hlobo e tla baka mokhathala oa mocheso. 

Mabapi le tšepe ea die-cast

Litšepe tse sebelisetsoang ho bolaea haholo li kenyelletsa zinki, koporo, aluminium, magnesium, lead, tin le li-alloys tsa lead-tin. Le hoja tšepe ea die-cast e sa tloaelehe, e boetse e ka khoneha. Litšepe tse ling tse khethehileng tse hlahisang lihlahisoa li kenyelletsa ZAMAK, alloy-zinc alloy, le litekanyetso tsa American Aluminium Association: AA380, AA384, AA386, AA390, le AZ91D magnesium. Litšobotsi tsa litšepe tse fapa-fapaneng nakong ea ho lahla lefu ke tse latelang:

• Zinc: Tšepe eo ho leng bonolo ho e lahla. Ho na le chelete e ngata ho etsa likaroloana tse nyane, ho bonolo ho roala, ho na le matla a phahameng a khatello, polasetiki e phahameng, le bophelo bo bolelele ba ho lahla.

 Aluminium: Boima bo bobebe, botsitso bo phahameng ha ho etsoa li-castings tse rarahaneng le tse tšesaane tse nang le marako, ho hanyetsa kutu e matla, thepa e ntle ea mochine, mocheso o phahameng oa mocheso le motlakase, le matla a phahameng ka mocheso o phahameng.

 Magnesium: Ho bonolo ho etsoa ka mochini, e na le karo-karolelano e phahameng ea boima ba 'mele,' me ke eona e bobebe ho fetisisa har'a litšepe tse sebelisoang hangata.

• Koporo: Ho thatafala ho hoholo, ho hanyetsa ho bola ho matla, thepa e ntle ka ho fetesisa ea litšepe tse sebelisoang hangata, ho hanyetsa, le matla a haufi le tšepe.

 Lead le Tin: boima bo phahameng, ho nepahala ho phahameng, ho ka sebelisoa e le likarolo tse khethehileng tsa anti-corrosion. Bakeng sa lintlha tsa bophelo bo botle ba sechaba, motsoako ona o ke ke oa sebelisoa e le lisebelisoa tsa ho lokisa le ho boloka lijo. Alloy ea lead, tin le antimony (ka linako tse ling e na le koporo e nyane) e ka sebelisoa ho etsa mofuta oa letsoho le bronzing khatisong ea letterpress.

Sebaka sa kopo:

Likarolo tsa li-die-casting ha li sa lekanyetsoa indastering ea likoloi le indasteri ea lisebelisoa, 'me butle-butle li atolosetsoa likarolong tse ling tsa indasteri, joalo ka mechini ea temo, indasteri ea lisebelisoa tsa mochini, indasteri ea lisebelisoa tsa elektroniki, indasteri ea ts'ireletso, likhomphutha, lisebelisoa tsa bongaka, lioache, lik'hamera le letsatsi le letsatsi. hardware, joalo-joalo Indasteri, ka ho khetheha: likarolo tsa likoloi, lisebelisoa tsa thepa ea ka tlung, lisebelisoa tsa ho hlapela (kamore ea ho hlapela), likarolo tsa mabone, lipapali, li-shavers, li-clips tsa thae, likarolo tsa motlakase le tsa elektronike, mabanta a mabanta, mekotla ea ho shebella, litšepe tsa tšepe, liloko, li-zippers, joalo-joalo.

Amolemo:

1. Boleng bo botle ba sehlahisoa

Ho nepahala ha dimensional tsa castings ho phahame, ka kakaretso ho lekana le 6 ~ 7, esita le ho fihla ho 4; qetello ea bokaholimo e ntle, ka kakaretso e lekana le 5 ~ 8; matla le boima li phahame, 'me matla ka kakaretso a phahame ka 25 ~ 30% ho feta ho lahla lehlabathe, empa a atolosoa Sekhahla se fokotsehile ka hoo e ka bang 70%; boholo bo tsitsitse, 'me ho fapanyetsana ho molemo; e ka etsa li-castings tse rarahaneng tse nang le marako a tšesaane.

2. Ts'ebetso e phahameng ea tlhahiso

3. Phello e babatsehang ea moruo

Ka lebaka la boholo bo nepahetseng ba "die-casting", bokaholimo bo boreleli ebile bo hloekile. Ka kakaretso, e sebelisoa ka ho toba ntle le ts'ebetso ea mechine, kapa molumo oa ho sebetsa o monyenyane, kahoo ha o ntlafatse tekanyo ea tšebeliso ea tšepe feela, empa hape o fokotsa palo e kholo ea lisebelisoa tsa ho sebetsa le lihora tsa motho; theko ea castings e bonolo; e ka kopanngoa le die-casting le lisebelisoa tse ling tsa tšepe kapa tse seng tsa tšepe . Ha e boloke feela lihora tsa kopano empa hape le tšepe.

Mefokolo:

Litsenyehelo tsa lisebelisoa tsa ho lahlela le hlobo li phahame, kahoo mokhoa oa ho etsa li-die-casting hangata o sebelisoa feela ho etsa lihlahisoa tse ngata ka lihlopha, 'me tlhahiso ea li-batch tse nyenyane ha e na litšenyehelo.

QY Precision e na le boiphihlelo bo felletseng ho Die Casting Process, mme e fana ka litharollo tse fapaneng ho fihlela tlhoko ea hau. U ka khetha e loketseng bakeng sa lihlahisoa tsa hau tsa ho qetela le 'maraka. Rea u amohela ho romella litšoantšo tsa hau tsa 2D/3D bakeng sa khotheishene ea mahala.
