Xa usiva 'ukuchaneka okuphezulu kwe-magnesium alloy die casting', umfanekiso ongoko nangoko uhlala uyindawo engenasiphako, enodonga olucekethekileyo, entsonkothileyo ephuma ediyeni, elungele ukudityaniswa. Yeyona nto ifanelekileyo yokuthengisa. Inyani, eyona nto sizamana nayo yonke imihla, kukuba ukufezekisa ukuchaneka okuphezulu kwi-Mg alloys kuncinci malunga ne-alloy ngokwayo kwaye ngaphezulu malunga nokulawula yonke into eyenzekayo phambi kokuba isinyithi sichukumise umngxuma wokufa. Yinkqubo, hayi inkqubo enye. Abathengi abaninzi beza becinga ukuba umlingo ukwi ingxubevange ye-magnesium ifomula-AZ91D vs. AM60B-kwaye ngeli xesha ibalulekile, ndingaxoxa uyilo lwesango, ulawulo lobushushu bokufa, kunye neeparamitha zeprofayile ezidutyulweyo zihlala zenza okanye zaphula isitaki sonyamezelo phambi kokuba sithethe ngesesibini. CNC Machining.
ISiseko: Kutheni iMagnesium, kwaye Kutheni Ikhohlisayo
Sisebenza ngezinto ezininzi kwi-QSY-i-stainless, i-nickel-based alloys yeendawo ezigqithisileyo-kodwa i-magnesium alloy die casting ithatha i-niche ekhethekileyo. Isibheno sicacile: amandla amangalisayo-kuya-ubunzima, ukumanzisa okulungileyo, ubugcisa obugqwesileyo. Kodwa udumo lwayo lokuba 'lula' ukuphosa luyalahlekisa. Ewe, iqukuqela njengamanzi xa kuthelekiswa ne-aluminiyam, izalisa iindawo ezibhityileyo kakuhle. Nantso into ephezulu. Icala elisezantsi kukuba ulwelo olufanayo lubangela ukuba kube lula ukuzaliswa kwesiphithiphithi ukuba inkqubo yokudutyulwa ayilungiswanga ngokugqibeleleyo, okukhokelela ekungeneni komoya kunye ne-porosity kanye apho ungayifuniyo-kwiindawo ezimiselwe ukuchaneka okuphezulu umatshini kamva. Awunakho umatshini kwi pore.
Ndikhumbula iprojekthi ye-sensor yezindlu kwiminyaka embalwa edlulileyo. Inxalenye yayinonyamezelo lwe-0.05mm kwi-bore ebalulekileyo. Sisebenzise ialloyi yeprimiyamu, kodwa izithonga zokuqala zasilela ekuhlolweni. Umba yayingekobunyulu bengxubevange; ibikukungahambelani kweqondo lobushushu. Esinye isiqingatha sokufa sasiqhuba i-30 ° C epholileyo kunesinye, ibangela ukuqina okungalinganiyo kunye ne-warpage eyabulala ukuchaneka. Kuye kwafuneka sibuyisele imigca yokupholisa eyongezelelweyo kwaye sihambe nenkqubo yokupholisa ipulsed. Olu luhlobo lwezandla zokulungisa igama elithi 'uchaneko oluphezulu' lifuna ngokuthe cwaka.
Kulapho imvelaphi yethu ikhoyo iqokobhe ngundo ukuphosa kwaye utyalo mali kuba ezinye iintsimbi okunene wazisa umsebenzi wethu Mg die casting. Ezo nkqubo zonke zimalunga nolawulo olucokisekileyo lwe-thermal kunye ne-gating ukufezekisa uzinzo lwe-dimensional. Sisebenzisa ifilosofi efanayo yokulawula indlela yokuqinisa, kanye ngexesha lomjikelo okhawulezayo. Yingqondo.
I-Die ligorha elingadumanga (okanye i-villain)
Ukuba uyafuna Ukuchaneka okuphezulu kwe-magnesium alloy die casting, qala ngokutshala i-60% yomzamo wakho kunye nohlahlo lwabiwo-mali kuyilo lokufa kunye nokwakhiwa. Ukufa okulungileyo kwe-Mg ayisiyonto nje ibhloko yentsimbi eqinile. Ulawulo lwemitha ye-thermal lubaluleke kakhulu. Sihlala sisebenzisa amajelo okupholisa ngokusesikweni kufutshane neempawu ezibalulekileyo ngoku, into esiyifundileyo yayingenakuxoxisana ngeendawo ezinyamezelayo. Ibakala lentsimbi yokufa nalo libalulekile-i-H13 isemgangathweni, kodwa kwimisebenzi ehlala ixesha elide, echanekileyo, inqanaba leprimiyamu elinokumelana nokudinwa okuthe kratya okutshisayo lihlawula ngokugcina imilinganiselo yecango kumawaka emijikelo.
Ukukhupha umoya kobunye ubugcisa obuchuliweyo. I-Mg idinga ukungena komoya okundlongondlongo ngakumbi kune-aluminiyam ngenxa yokuzaliswa ngokukhawuleza, kodwa iivents kufuneka zibekwe kunye nobukhulu ukunqanda ukukhanya ngelixa uvumela umoya ukuba uphume. Rhoqo, ndikhe ndabona ukufa apho iifestile zazicingelwa emva koko, zikhokelela kwiipokotho zerhasi ezitshileyo ezibonakala ngathi ziziphene ezingaphezulu kwaye ziyonakalisa. ukuchaneka okuphezulu imfuneko yokugqiba umgangatho. Lulungelelwano phakathi kwesantya sokuzalisa kunye nempumelelo yokukhupha umoya othi ufunde kuphela ngokudubula iindawo ezininzi ezimbi kuqala.
Siye sasebenzisana nevenkile yezixhobo kwi-die for a lightweight drone component. Uyilo lokuqala lwalunamasango e-aluminiyam eencwadi.
