OEM zinc ingxubevange die Casting
I-Zinc die casting iyinqubo yokukhiqiza esebenza kahle kakhulu evame ukusetshenziselwa ukwakha izingxenye zensimbi eziyinkimbinkimbi ngokunemba okuphawulekayo nokuqina. Ngokungafani nezinye izindlela zokukhiqiza, i-die casting ivumela ukukhiqizwa ngobuningi bezingxenye ezifaka ijometri eyinkimbinkimbi, imininingwane emihle, kanye nokuqedwa okuhle kakhulu kwendawo, konke ngenkathi kugcinwa ukubekezelelana okuqinile.
Kulesi sihloko, sihlola inqubo ye-zinc die casting futhi sihlole izinzuzo ezibalulekile zokusebenzisa ama-alloy e-zinc ekufakweni kwe-die cast, okuhlanganisa ukuguquguquka kwengxenye yedizayini ethuthukisiwe, ukuphumelela kwezindleko, nokusebenza komshini okuphakeme.
Iyini i-Zinc Die Casting?
Ku-die casting, ama-alloys e-zinc ayancibilika futhi ajovwe ezibunjeni zensimbi ngaphansi kwengcindezi ephezulu. Le nqubo ivumela insimbi encibilikisiwe ukuthi igcwalise izimo zokubunjwa eziyinkimbinkimbi ngokushesha nangokunembile.Iphuzu lokuncibilika eliphansi le-Zinc(cishe u-387-390°C) ikwenza kube kuhle kulokhu. Ngemuva kokupholisa, insimbi ithatha ukuma okuqondile kwesikhunta, inciphisa isidingo sokucubungula okwengeziwe.
Kungani Khetha i-Zinc Yokusakaza?
Inzuzo ye-Zinc die casting ukuthi i-zinc inoketshezi oluningi uma incibilikiswa, okusho ukuthi ingakha izimo eziyinkimbinkimbi ngokunemba. Yakhoamandla nomthelela ukumelananazo izici ezivelele.
Ngokungafani nezinye izinsimbi, i-zinc igcina ubuqotho bayo bemishini ngokuhamba kwesikhathi. Izindleko ze-zinc ziphansi kakhulu, futhi zengeza ekuthandeni kwayo ukukhiqiza. Ngaphezu kwalokho, ivumela imijikelezo yokukhiqiza esheshayo ngoba iphola futhi iqine ngokushesha.
Iyini i-Zinc Die Casting Process?
Isinyathelo sokuqala kule nqubo sihilela ukuklama nokudala idayi, ngokuvamile eyenziwa ngensimbi yezinga eliphezulu. I-die empeleni iyisikhunta esibi sengxenye ezophonswa. Ngaphambi kwanoma yikuphi ukubunjwa, isikhunta siyagcotshwa, okusiza ekukhipheni kalula ingxenye eqediwe futhi kwandise isikhathi sokuphila sesikhunta.
Khona-ke, i-zinc noma i-zinc alloy iyancibilika esithandweni ekushiseni okuphansi. I-zinc encibilikisiwe ijova emgodini we-die ngokucindezela okukhulu kakhulu kusetshenziswa i-cold chamber noma umshini we-hot-chamber die casting machine.
Le ndlela yokucindezela okuphezulu iqinisekisa ukuthi i-zinc encibilikisiwe igcwalisa ngisho nembotshana encane futhi ikhiqize izingxenye eziyinkimbinkimbi, ezinemininingwane enokusimama okuhle kakhulu kwe-dimensional.
Uma isijovwe, i-zinc encibilikisiwe iphola ngokushesha futhi iqine ngaphakathi kwe-die cavity. Ngenxa yezinga layo eliphansi lokuncibilika, i-zinc iqina ngokushesha kunezinye izinsimbi eziningi, okusho ukuthi izingxenye zingakhishwa kufayizi ngemizuzwana eyi-15 ukuya emizuzwini embalwa kuye ngobukhulu nobunkimbinkimbi bazo.
Ngemuva kokuthi insimbi iqina futhi ifinyelele amandla okusebenza anele, i-die iyavulwa, futhi ingxenye ikhishwe kusetshenziswa izikhonkwane ze-ejector. Ingxenye (eyaziwa nangokuthi “ukusakaza”) igcina umumo onembile wedayizi.
Ngokuya ngezidingo zomkhiqizo wokugcina, ukuqedwa kwendawo kungabandakanya ukupholishwa, ukuqhunyiswa okulimazayo, ukupenda, noma ukufaka izinto ezivikelayo, ezifana ne-electroplating (isb, i-chrome, i-nickel).

Uma uqhathanisa i-zinc nezinsimbi ezifana ne-aluminium ne-magnesium, kunomehluko obonakalayo.I-Zinc ine-fluidity engcono, okuholela emininingwaneni emihle. Nakuba i-aluminium ingasindi futhi inamandla, ama-alloys e-zinc ngokuvamile ahlinzeka ukumelana nokugqoka okuphezulu.Magnesiumingase ibe lula, kodwa i-zinc ngokuvamile inikeza ukuqina namandla okwengeziwe.
I-Zinc die casting ihamba phambili ekukhiqizeni izingxenye ezinokunemba kwe-dimensional ephezulu. Ayithandeki kangako ekujikeni uma iqhathaniswa nozakwabo be-aluminium. Yakhoukumelana nokugqwala okuhlekanye nekhono lokugqitshwa kalula noma ukuqedwa kukwenza kube ukukhetha okuguquguqukayo kwezinhlelo zokusebenza ezahlukahlukene
Ungakhetha kanjani i-Zinc Alloy ye-Zinc Casting?
Uma kukhulunywa nge-zinc die casting, ukukhetha ingxubevange efanele kubalulekile ngoba kuthinta amandla, ukuqina, kanye nokuba lula kokukhiqiza. Ama-alloys e-zinc ahlukene anezici ezihlukile eziwenza afanelekele ukusetshenziswa okuhlukahlukene.

Yiziphi izinhlelo zokusebenza zeZinc Casting Parts?
I-Zinc die casting inikezela ngezinzuzo eziningi ezimbonini ezahlukahlukene ngokunikeza ukunemba okuphezulu, ukuguquguquka ekwakhiweni, kanye nezakhiwo eziqinile zomzimba.
Izimboni Eziqondiwe kanye Nezicelo Zokusebenzisa Ekugcineni
I-Zinc die casting isetshenziswa kabanzi emboniniimboni yezimoto, kufaka phakathi izingxenye ezifana nezingxenye zamabhuleki ngenxa yobuhle bayoamandla omthelelakanye nekhono lokudala imiklamo eyinkimbinkimbi. Kuyathandwa futhi ekukhiqizweni kwehadiwe, ama-electronics abathengi, nezinto zikagesi. Uzothola i-zinc die casting emikhiqizweni edinga ukusebenza okuthembekile nokuqedwa okukhangayo.
Ngaphezu kokusetshenziswa kwezimoto, lawa ma-alloys asetshenziswa endaweniukwenziwa kwamathuluzikanye nezingxenye zemishini, lapho amandla nemininingwane ibalulekile. Ukuguquguquka kwe-zinc die casting kukwenza kube ukukhetha ezintweni ezidinga zombiliijometri eyinkimbinkimbinokukhuthazela okuhlala isikhathi eside.
imibuzo ejwayelekile ukubuzwa
I-zinc iqhathaniswa kanjani ne-aluminium die casting mayelana nokuqina nezindleko?
Izibungu zeZinc zihlala isikhathi eside kune-aluminium ngenxa yokumelana kwazo kangcono. Lokhu kubenza babe inketho ehlala isikhathi eside ekukhiqizeni. Ngokwezindleko, i-aluminiyamu noma ingxubevange ye-aluminium ilula futhi ingase ishibhile ezingxenyeni ezinkulu, kodwa i-zinc ingonga kakhulu ezintweni ezincane, ezinemininingwane ngenxa yokunemba namandla ayo.
Ungakwazi yini ukuchaza umehluko phakathi kwe-zinc nensimbi engagqwali ekusetshenzisweni kwe-die casting?
I-Zinc ithambile futhi iyathandeka, evumela ukuthi kube nezimo nemiklamo eyinkimbinkimbi. Insimbi engagqwali, nakuba inamandla kakhulu, ilukhuni ukuyisakaza futhi isetshenziselwa ikakhulukazi imikhiqizo edinga amandla engeziwe nokumelana. I-Zinc nayo ayibizi kakhulu futhi ingcono ekwakheni izingxenye eziningi ezinemininingwane emihle.
Yiziphi izici ezibalulekile okufanele uzicabangele lapho ukhetha umshini wokuphonsa we-zinc die?
Bheka imishini ehlinzeka ngokulawula okunembile kwezinga lokushisa nokucindezela ukuze uqinisekise ukulingwa kwekhwalithi ephezulu. Cabangela amandla omshini wokuphatha usayizi othize nobunkimbinkimbi bezingxenye zakho. Ukusebenza kahle kanye nokulungisa kalula nakho kubalulekile empumelelweni yokukhiqiza yesikhathi eside.
Yini abakhiqizi okufanele bayibheke ukuze bavimbele izinkinga ezijwayelekile ekufakweni kwe-zinc die?
Abakhiqizi kufanele balawule izinga lokushisa lesikhunta kanye nokucindezela ngokunembile ukuze bagweme ukonakala kokusakaza. Ukuhlola isikhunta njalo ukuze kuguge kungavimbela izinkinga ezihlobene nokuwohloka kwamathuluzi. Futhi, ukusebenzisa i-zinc alloys yekhwalithi ephezulu nokugcina izindawo zokukhiqiza ezihlanzekile kusiza ukuqinisekisa ubuqotho kanye nekhwalithi yemikhiqizo yokugcina.
