OEM zinc ingxubevange die casting
I-Zinc die casting yinkqubo yokwenziwa esebenza ngokugqibeleleyo edla ngokusetyenziswa ukwenza amacandelo esinyithi antsonkothileyo ngokuchaneka okumangalisayo kunye nokuqina. Ngokungafaniyo nezinye iindlela zokuvelisa, ukuphosa ukufa kuvumela ukuveliswa kwezinto ezininzi ezibonisa iijiyometri ezintsonkothileyo, iinkcukacha ezintle, kunye nokugqitywa komphezulu ogqwesileyo, ngelixa ugcina unyamezelo oluqinileyo.
Kweli nqaku, siphonononga inkqubo yokuphosa i-zinc die kwaye sijonge kwiingenelo eziphambili zokusebenzisa i-zinc alloys kwi-die casting, kubandakanya ukuguquguquka koyilo lwenxalenye ephuculweyo, ukusebenza kakuhle kweendleko, kunye nokusebenza okuphezulu koomatshini.
Yintoni iZinc Die Casting?
Kwi-die casting, i-alloys ye-zinc iyancibilika kwaye ifakwe kwi-molds yensimbi phantsi koxinzelelo oluphezulu. Le nkqubo ivumela isinyithi esityhidiweyo ukuba sizalise iimilo zokubumba eziyinkimbinkimbi ngokukhawuleza nangokuchanekileyo.Iqondo eliphantsi lokunyibilika kweZinc(malunga ne-387-390 ° C) yenza ukuba ilungele oku. Emva kokupholisa, isinyithi sithatha imo echanekileyo yokubumba, ukunciphisa imfuno yokulungiswa okongeziweyo.
Kutheni ukhetha iZinc yokuCasa?
I-advanteji ye-Zinc die casting kukuba i-zinc imanzi kakhulu xa inyibilika, oku kuthetha ukuba inokudala iimilo eziyinkimbinkimbi ngokuchaneka. Yaloamandla kunye nokumelana nempembelelozikwayimpawu ezibalaseleyo.
Ngokungafaniyo nezinye isinyithi, i-zinc igcina ingqibelelo yayo yomatshini ekuhambeni kwexesha. Iindleko ze-zinc ziphantsi, kwaye zongeza kwisibheno sayo sokuvelisa. Ngaphezu koko, ivumela imijikelo yemveliso ekhawulezayo kuba iphola kwaye iqine ngokukhawuleza.
Yintoni iZinc Die Casting Process?
Isinyathelo sokuqala kwinkqubo ibandakanya ukuyila nokudala i-die, edlalwa ngokuqhelekileyo kwintsimbi ephezulu. Idayi ingumngundo ongalunganga wenxalenye eza kuphoswa. Ngaphambi kwayo nayiphi na into yokubunjwa, i-mold ifakwe i-lubricated, inceda ekususeni lula inxalenye egqityiweyo kwaye yandisa ixesha lokuphila lokungunda.
Emva koko, i-zinc okanye i-zinc alloy iyancibilika kwisithando somlilo kwiqondo lokushisa eliphantsi. I-zinc etyhidiweyo itofwa kumngxuma wokufa ngoxinzelelo oluphezulu kakhulu kusetyenziswa igumbi elibandayo okanye umatshini wokujula wegumbi elishushu.
Le ndlela yoxinzelelo oluphezulu iqinisekisa ukuba i-zinc etyhidiweyo igcwalisa owona mngxuma omncinci kwaye ivelise iindawo eziyinkimbinkimbi, ezineenkcukacha ezinozinzo olubalaseleyo lwe-dimensional.
Nje ukuba itofwe, i-zinc etyhidiweyo iphola ngokukhawuleza kwaye yomelele ngaphakathi kumngxuma wokufa. Ngenxa yeqondo eliphantsi lokunyibilika kwayo, i-zinc yomelela ngokukhawuleza kunezinye iintsimbi ezininzi, oku kuthetha ukuba iinxalenye zinokukhutshelwa ekufeni ngemizuzwana eyi-15 ukuya kwimizuzu embalwa ngokuxhomekeke kubungakanani kunye nobunzima bazo.
Emva kokuba isinyithi siqina kwaye sifikelele kumandla aneleyo omatshini, ukufa kuyavulwa, kwaye inxalenye ikhutshwe ngokusebenzisa izikhonkwane ze-ejector. Inxalenye (ekwaziwa ngokuba “yi-casting”) igcina ubume obuchanekileyo bokufa.
Ngokuxhomekeke kwiimfuno zemveliso yokugqibela, ukugqitywa komphezulu kunokubandakanya ukupolishwa, ukugqabhuka kwe-abrasive, ukupeyinta, okanye ukufaka iingubo zokukhusela, ezifana ne-electroplating (umzekelo, i-chrome, i-nickel).
