I-Metal Injection Molding (MIM) iwuhlobo olusha lobuchwepheshe be-Powder metallurgy, obuthuthukiswe ngokubumba umjovo wempushana (PIM) wezingxenye zobumba. Izinyathelo eziyinhloko zokukhiqiza ze-Metal Injection Molding zimi kanje: ukuxuba impushana yensimbi kanye ne-binder-granulation-injection molding-degreasing-sintering-olandelayo umkhiqizo wokugcina wokwelapha, ubuchwepheshe bufanele ukukhiqizwa okuncane, okuyinkimbinkimbi, okuphezulu kokusebenza okuphezulu kwe-Powder metallurgy. izingxenye, njengalezo ezisetshenziswa imboni yewashi yaseSwitzerland ukwenza izingxenye zewashi. Emashumini eminyaka amuva nje, ubuchwepheshe be-MIM buthuthuke ngokushesha, izinto ezisetshenziswayo zifaka: I-Fe-Ni ingxubevange, insimbi engagqwali, insimbi yamathuluzi, ingxubevange ye-gravity ephezulu, i-carbide enosimende, i-titanium alloy, i-ni-based superalloy, i-intermetallic compound, i-alumina, i-zirconia nokunye. ku. Ubuchwepheshe be-Metal Injection Molding (MIM) budinga ukuthi usayizi wezinhlayiyana zempushana ube ngaphansi kwe-micron futhi umumo ucishe ube yindilinga. Ngaphezu kwalokho, ukuminyana okuxekethile, ukuminyana okudlidlizayo, isilinganiso sobude nobubanzi, i-engeli ye-slope yemvelo kanye nokusabalalisa usayizi wezinhlayiyana nakho kuyadingeka. Njengamanje, izindlela eziyinhloko zokukhiqiza impushana yobuchwepheshe bokubumba umjovo wensimbi yi-atomization yamanzi, i-atomization yegesi kanye nendlela yeqembu le-carbonyl. Imikhiqizo yempushana evame ukusetshenziswa yokujova izinsimbi zensimbi engagqwali yilezi: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, njll. Inqubo ye-atomization yamanzi imi kanje: ukukhethwa kwensimbi engagqwali impahla eluhlaza-encibilika ku-medium frequency induction-composition adjustment-deoxidation kanye ne-slag remove-atomization kanye ne-pulverization-quality discovery-screening-packaging and storage, amathuluzi amakhulu asetshenziswayo yilezi: isithando somlilo se-medium-frequency induction, iphampu yamanzi enengcindezi ephezulu, idivayisi evaliwe yokuhlikihla, ithangi lamanzi elijikelezayo, imishini yokuhlola kanye nokupakisha, imishini yokuhlola.

Inqubo yeigesi atomizationimi kanje:

ukukhetha insimbi engagqwali impahla eluhlaza-ukuncibilika ku-middle frequency induction-composition adjustment-deoxidation kanye nokususwa kwe-slag-atomization kanye ne-pulverization-quality discovery-screening-packaging and storage. Imishini eyinhloko esetshenziswayo yilena: isithando somlilo esincibilikisa imvamisa emaphakathi, umthombo we-nitrogen kanye nedivaysi ye-atomization, ithangi lamanzi elijikelezayo, imishini yokuhlola nokupakisha, izinto zokuhlola. Indlela ngayinye inezinzuzo zayo kanye nebubi bayo: I-Atomization Yamanzi iyinqubo eyinhloko yokugaya, ukusebenza kahle kwayo okuphezulu, ukukhiqizwa okukhulu kunomnotho, kungenza i-powder ibe yinhle, kodwa ukwakheka kungavamile, okuvumela ukulondolozwa, kodwa isibopho esisetshenziswe kakhulu, sithinte ukunemba. Ngaphezu kwalokho, ifilimu ye-oxidation eyakhiwe ukusabela kwamanzi nensimbi ekushiseni okuphezulu ivimbela ukubola. I-Gas Atomization iyindlela eyinhloko yokukhiqiza impushana yobuchwepheshe bokubumba umjovo wensimbi. Impushana ekhiqizwe i-atomization yegesi iyindilinga, ine-oxidation degree ephansi, i-binder edingekayo kancane futhi ibukeka kahle, kodwa isivuno se-ultra-fine powder siphansi, intengo iphezulu kanye nokugcinwa komumo kumpofu, c, N, H, I-O in binder inomthelela emzimbeni we-sintered. Impushana ekhiqizwa indlela ye-carbonyl iphezulu ngobumsulwa, izinzile ekuqaleni futhi inhle kakhulu ngosayizi wezinhlayiyana. Ifaneleka kakhulu ku-MIM, kodwa kuphela i-Fe, i-Ni nezinye izimpushana, ezingakwazi ukuhlangabezana nezidingo zezinhlobonhlobo. Ukuze kuhlangatshezwane nezidingo zempushana yokubumba umjovo wensimbi, izinkampani eziningi ziye zathuthukisa izindlela ezingenhla futhi zathuthukisa izindlela ze-micro-atomization kanye ne-laminar atomization. Manje ngokuvamile amanzi i-athomu powder kanye negesi i-athomu ukusetshenziswa powder okuxubile, yangaphambili ukuthuthukisa ukuminyana of compaction, yokugcina ukugcina ijamo. Njengamanje, ukusebenzisa i-atomizing powder yamanzi kungabuye kukhiqize umzimba we-sintered onobuningi obuhlobene ngaphezu kuka-99%, ngakho-ke i-powder ye-atomizing yamanzi kuphela isetshenziselwa izingxenye ezinkulu, futhi i-gas atomizing powder isetshenziselwa izingxenye ezincane. Eminyakeni emibili edlule, i-Handan Rand Atomizing Pulverizing Equipment Co., Ltd. iye yasungula uhlobo olusha lwemishini yokugaya i-atomizing, engakwazi kuphela ukuqinisekisa ukukhiqizwa okukhulu kwe-atomizing yamanzi kanye ne-ultrafine powder, kodwa futhi icabangele izinzuzo zesimo sempuphu esiyindilinga.
