I-Metal Injection Molding (MIM) luhlobo olutsha lwetekhnoloji ye-Powder metallurgy, eyenziwe nge-powder injection molding (PIM) yeendawo ze-ceramic. Amanyathelo aphambili emveliso ye-Metal Injection Molding ngala alandelayo: ukuxuba umgubo wesinyithi kunye ne-binder-granulation-injection molding-degreasing-sintering-subsequent treatment-final product, le teknoloji ifanelekile kwimveliso encinci, enzima, esebenza kakhulu ye-Powder metallurgy parts, efana naleyo isetyenziswa lishishini lewotshi laseSwitzerland ukwenza iindawo zewotshi. Kwiminyaka yakutshanje, itekhnoloji ye-MIM iphuhlise ngokukhawuleza, izixhobo ezifanelekileyo ziquka: i-Fe-Ni alloy, intsimbi engatyiwayo, intsimbi yesixhobo, i-high specific gravity alloy, i-cemented carbide, i-titanium alloy, i-ni-based superalloy, i-intermetallic compound, i-alumina, i-zirconia njalo njalo. Itekhnoloji ye-Metal Injection Molding (MIM) ifuna ukuba ubungakanani be-particle ye-powder bungaphantsi kwe-micron kwaye imo iphantse ibe yi-spherical. Ukongeza, kufuneka uxinano olukhululekileyo, uxinano olushukumayo, umlinganiselo wobude ukuya kububanzi, i-angle ye-slope yendalo kunye nokusasazwa kobungakanani be-particle. Okwangoku, iindlela eziphambili zokuvelisa ipowder kwiteknoloji yokubumba inaliti yesinyithi yi-atomization yamanzi, i-atomization yegesi kunye nendlela yeqela le-carbonyl. Iimpawu zepowder ezisetyenziswa kakhulu ekufakweni kweentsimbi zentsimbi engagqwali zezi: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, njl. Inkqubo ye-atomization yamanzi yile ilandelayo: ukukhethwa kwezinto eziluhlaza zentsimbi engagqwali-ukunyibilika kwi-medium frequency induction furnace-ukulungiswa kokwakheka-ukususwa kwe-oxidation kunye ne-slag-ukususwa kwe-atomization kunye ne-pulverization-ukufunyanwa komgangatho-ukuhlolwa-ukupakisha kunye nokugcinwa, izixhobo eziphambili ezisetyenziswayo zezi: i-medium-frequency induction furnace, i-high-pressure water pump, isixhobo sokucola esivaliweyo, itanki yamanzi ejikelezayo, izixhobo zokuvavanya kunye nokupakisha, izixhobo zokuvavanya.

Inkqubo yei-atomization yegesingolu hlobo lulandelayo:

ukukhetha izinto eziluhlaza zentsimbi engagqwaliyo-ukunyibilika kwi-medium frequency induction furnace-ukulungiswa kokwakheka-ukususwa kwe-deoxidation kunye ne-slag-ukususwa kwe-atomization kunye ne-pulverization-ukuchonga umgangatho-ukuhlola-ukupakisha kunye nokugcina. Izixhobo eziphambili ezisetyenziswayo zezi: i-medium frequency induction melting furnace, umthombo we-nitrogen kunye nesixhobo se-atomization, itanki yamanzi ejikelezayo, izixhobo zokuvavanya kunye nokupakisha, izixhobo zokuvavanya. Indlela nganye ineenzuzo kunye neengxaki zayo: I-Water Atomization yinkqubo ephambili yokucola, ukusebenza kwayo okuphezulu, imveliso enkulu inoqoqosho ngakumbi, inokwenza i-powder ibe ntle, kodwa imo ayilunganga, nto leyo evumela ukugcinwa kwesimo, kodwa i-binder esetyenziswa ngakumbi, ichaphazela ukuchaneka. Ukongeza, ifilimu ye-oxidation eyenziwe yimpendulo yamanzi kunye nesinyithi kubushushu obuphezulu iyathintela ukubola. I-Gas Atomization yindlela ephambili yokuvelisa i-powder yetekhnoloji yokubumba i-injection yesinyithi. Umgubo oveliswa yi-atomization yegesi ungqukuva, unezinga eliphantsi le-oxidation, udinga i-binder encinci kwaye ukwakheka kakuhle, kodwa isivuno se-ultra-fine powder siphantsi, ixabiso liphezulu kwaye ipropathi yokugcina imo ayilunganga, i-c, i-N, i-H, i-O kwi-binder inefuthe emzimbeni osikiweyo. Umgubo oveliswa yindlela ye-carbonyl uphezulu ngobumsulwa, uzinzile ekuqaleni kwaye ucolekile kakhulu ngobukhulu bamasuntswana. Ufaneleke kakhulu kwi-MIM, kodwa kuphela kwi-Fe, i-Ni kunye nezinye iipowder, ezingenako ukuhlangabezana neemfuno zeentlobo ezahlukeneyo. Ukuze kuhlangatyezwane neemfuno zepowder yokubumba i-metal injection, iinkampani ezininzi ziye zaphucula ezi ndlela zingasentla kwaye zaphuhlisa iindlela ze-micro-atomization kunye ne-laminar atomization. Ngoku kudla ngokusetyenziswa i-powder exutyiweyo ngamanzi kunye ne-gas atomized powder, eyokuqala ukuphucula uxinano lwe-compaction, eyokugqibela ukugcina imo. Okwangoku, ukusebenzisa i-water atomizing powder kunokuvelisa umzimba osikiweyo onoxinano olungaphezulu kwe-99%, ngoko ke kusetyenziswa i-water atomizing powder kuphela kwiindawo ezinkulu, kwaye i-gas atomizing powder isetyenziselwa iindawo ezincinci. Kwiminyaka emibini edlulileyo, iHandan Rand Atomizing Pulverizing Equipment Co., Ltd. iphuhlise uhlobo olutsha lwezixhobo zokucola i-atomizing, ezingayi kuqinisekisa kuphela ukuveliswa okukhulu kwe-atomizing yamanzi kunye ne-ultrafine powder, kodwa zikwaqwalasela neengenelo zesimo se-spherical powder.
