I-Metal Injection Molding (MIM) luhlobo olutsha lweteknoloji ye-Powder metallurgy, ephuhliswe kwi-powder injection molding (PIM) yeengxenye ze-ceramic. Amanyathelo aphambili emveliso ye-Metal Injection Molding yile ilandelayo: ukuxuba umgubo wesinyithi kunye ne-binder-granulation-injection molding-degreasing-sintering-elandelayo unyango-imveliso yokugqibela, iteknoloji ifanelekile kwimveliso encinci, eyinkimbinkimbi, ephezulu yokusebenza kwe-Powder metallurgy. iinxalenye, ezifana nezo zisetyenziswa yi-Swiss watch ishishini ukwenza iinxalenye iwotshi. Kumashumi eminyaka akutshanje, itekhnoloji ye-MIM iphuhliswe ngokukhawuleza, izixhobo ezisebenzayo zibandakanya: i-Fe-Ni ingxubevange, insimbi engenasici, insimbi yesixhobo, i-alloy ephezulu ye-gravity, i-carbide enesamente, i-titanium alloy, i-ni-based superalloy, i-intermetallic compound, i-alumina, i-zirconia kunye nokunye. kwi. Itekhnoloji ye-Metal Injection Molding (MIM) ifuna ukuba ubukhulu besuntswana lomgubo bungaphantsi kwe-micron kwaye imilo iphantse ibe yingqukuva. Ukongeza, ukuxinana okuxekethileyo, ukuxinana okungcangcazelayo, umlinganiselo wobude ukuya kwidayamitha, i-angle ye-slope yendalo kunye nokusabalalisa ubungakanani bamasuntswana nazo ziyafuneka. Okwangoku, iindlela eziphambili zokuvelisa umgubo wetekhnoloji yokubumba inaliti yesinyithi yi-atomization yamanzi, i-atomization yegesi kunye nendlela yeqela le-carbonyl. Iimpawu ezisetyenziswa ngokuqhelekileyo zomgubo ukutofa isinyithi sentsimbi: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, njl. Inkqubo ye-atomization yamanzi ngolu hlobo lulandelayo: ukukhethwa kwensimbi engenasici-enyibilikayo kwi-medium frequency induction induction-composition adjustment-deoxidation kunye nokususwa kwe-slag-atomization kunye ne-pulverization-quality found-screening-packaging kunye nokugcinwa, izixhobo eziphambili ezisetyenziswayo zezi: i-medium-frequency induction furnace, impompo yamanzi yoxinzelelo oluphezulu, isixhobo sokucofa esivaliweyo, itanki yamanzi ejikelezayo, izixhobo zokuhlola kunye nokupakishwa, izixhobo zokuvavanya.

Inkqubo yeigesi atomizationimi ngolu hlobo lulandelayo:

ukukhetha insimbi engenasici-encibilikayo kwi-furnace induction-composition adjustment-deoxidation kunye nokususwa kwe-slag-atomization kunye ne-pulverization-quality discovering-screening-packaging kunye nokugcinwa. Izixhobo eziphambili ezisetyenziswayo zezi: i-medium frequency induction melting furnace, umthombo we-nitrogen kunye nesixhobo se-atomization, itanki yamanzi ejikelezayo, izixhobo zokuhlola kunye nokupakishwa, izixhobo zokuvavanya. Indlela nganye ineenzuzo zayo kunye nokungalunganga: I-Atomization yamanzi yeyona nkqubo iphambili yokucoca, ukusebenza kwayo okuphezulu, imveliso enkulu inoqoqosho ngakumbi, inokwenza umgubo ucokiseke, kodwa imilo ayifani, nto leyo inceda ukumila ukulondolozwa, kodwa isibophelelo esetyenziswa kakhulu, kuchaphazela ukuchaneka. Ukongeza, ifilimu ye-oxidation eyenziwe ngokusabela kwamanzi kunye nesinyithi kwiqondo eliphezulu lobushushu lithintela i-sintering. I-Atomization yegesi yeyona ndlela iphambili yokuvelisa umgubo wetekhnoloji yokubumba inaliti yesinyithi. Umgubo oveliswa yi-atomization yerhasi ungqukuva, unedigri ephantsi ye-oxidation, i-binder encinci efunekayo kunye nokubumba kakuhle, kodwa isivuno somgubo we-ultra-fine siphantsi, ixabiso liphezulu kwaye ipropati yokugcina imilo imbi, c, N, H, O kwisibophelelo sinefuthe kumzimba we-sintered. I-powder eveliswa yindlela ye-carbonyl iphezulu ekucocekeni, izinzile ekuqaleni kwaye ihle kakhulu kwi-particle size. Eyona nto ifanelekileyo kwi-MIM, kodwa kuphela i-Fe, i-Ni kunye nezinye iipowder, ezingenako ukuhlangabezana neemfuno zeentlobo. Ukuze kuhlangatyezwane neemfuno zomgubo wokubumba inaliti yesinyithi, iinkampani ezininzi ziye zaphucula ezi ndlela zingasentla kwaye zaphuhlisa iindlela ze-micro-atomization kunye ne-laminar atomization. Ngoku ngokuqhelekileyo amanzi atomized umgubo kunye negesi atomized ukusetyenziswa umgubo exutyiweyo, yangaphambili ukuphucula ingxinano ukuxinana, le yokugqibela ukugcina imilo. Okwangoku, ukusebenzisa i-atomizing powder yamanzi kunokuvelisa umzimba we-sintered kunye noxinano oluhlobene ngaphezu kwe-99%, ngoko ke kuphela i-atomizing powder yamanzi isetyenziselwa iindawo ezinkulu, kwaye i-gas atomizing powder isetyenziselwa iindawo ezincinci. Kwiminyaka emibini edlulileyo, i-Handan Rand Atomizing Pulverizing Equipment Co. iingenelo zemilo yomgubo ongqukuva.
