Libopeho tse rarahaneng le ho mamellana ka thata
Zinc die casting e hlahisa li-cavity tse ngata, libopeho tse rarahaneng le ka har'a mamello e haufi ho feta mekhoa e meng e mengata ea tlhahiso.Ntle le ho hlahisa molumo o phahameng oa likarolo tse batlang li tšoana, e hlahisa mocheso o matla le ho roala likarolo tse hanyetsanang tse tsitsitseng, ha li ntse li boloka mamello e haufi haholo.
Mokhoa oa "die casting" o fa baqapi monyetla oa ho boloka litšenyehelo ka ho kopanya likarolo hore e be mofuta o le mong oa letlooa.Ka hona, ho ka felisa ts'ebetso ea bobeli joalo ka machining.Zinc die castings li entsoe ka katleho e le li-bearings (ho felisa li-alloys tsa bronze), li-rivets, 'me li ka kenya likhoele.Ka lebaka la melemo ena, li-die castings li fumaneha liindastering tse fapaneng tse kenyelletsang likoloi, lisebelisoa tsa meaho, lisebelisoa tsa elektroniki, thepa ea lipapali, jj.
Hoa lokela ho hlokomeloa hore mamello e tloaelehileng ea indasteri e ka finyelloa le / kapa ea fetisoa, haeba ho hlokahala bakeng sa moralo oa karolo.Leha ho le joalo, ho na le lintlha tse ngata tse lokelang ho nkoa, tse kang;sebopeho sa karolo, moo tšobotsi e leng teng ka har'a sesebelisoa, boemo ba eona ke bofe ka likarolo tse ling tsa karolo le haeba u pharalla ka mose ho mola oa karohano.Ha ho nahanoa ka bophelo ba lisebelisoa le litšenyehelo, ke mokhoa o motle ho lumella mamello e kholo le ho rala libakeng tse sa pheleng hantle, sebopeho kapa ts'ebetso le ho tiisa mamello feela libakeng tseo ho hlokahalang.

Li-alloys tsa zinc ke tsona tse bonolo ho feta khatello e phahameng.Li fana ka ductility e phahameng, matla a ts'usumetso, 'me e ka behoa habonolo.Li-alloys tsa zinc li na le ntlha e tlase ea ho qhibiliha ho feta aluminium e ka thusang ho ntlafatsa bophelo ba lefu.
Li-alloys tsa ZA ke lisebelisoa tsa tšepe tse thehiloeng ho zinki tse nang le aluminium e phahameng ho feta li-alloys tse tloaelehileng tsa zinki.Li-alloys tsena li na le litšoaneleho tse phahameng tsa matla, hape le boima bo phahameng le thepa ea ho jara hantle.
