Metal Injection Molding (MIM) ni ubwoko bushya bwa tekinoroji ya Powder metallurgie, ikozwe muburyo bwo guterwa ifu (PIM) yibice bya ceramic. Intambwe nyamukuru yumusaruro wibyuma byo gutera inshinge nuburyo bukurikira: kuvanga ifu yicyuma na binder-granulation-inshinge molding-degreasing-sintering-nyuma yo kuvura-ibicuruzwa byanyuma, tekinoloji irakwiriye kubyara umusaruro muto, utoroshye, ukora cyane Powder metallurgie ibice, nkibikoreshwa ninganda zo mu Busuwisi zikora amasaha yo gukora ibice. Mu myaka ya vuba aha, ikoranabuhanga rya MIM ryateye imbere byihuse, ibikoresho bikoreshwa birimo: Fe-Ni alloy, ibyuma bitagira umwanda, ibyuma byabikoresho, ibyuma byihariye bya rukuruzi rukomeye, karbide ya sima, titanium alloy, ni ishingiye kuri superalloy, intermetallic compound, alumina, zirconia nibindi ku. Ikoranabuhanga rya Metal Injection Molding (MIM) risaba ko ingano yifu yifu iri munsi ya micron kandi imiterere ni hafi. Byongeye kandi, ubucucike bworoshye, ubwinshi bwinyeganyeza, igipimo cyuburebure na diametre, inguni yimisozi ihanamye hamwe nogukwirakwiza ingano. Kugeza ubu, uburyo nyamukuru bwo gukora ifu yubuhanga bwo gutera inshinge ni uburyo bwo gukoresha amazi, atomisiyasi ya gaz hamwe nuburyo bwa groupe ya karubone. Ibiranga ifu ikoreshwa cyane mugutera inshinge zicyuma ni: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, nibindi. Inzira ya atomisiyasi yamazi nuburyo bukurikira: gutoranya ibyuma bitagira umwanda ibikoresho-bishonga mugihe giciriritse cyo kwinjiza itanura-ibice byo guhinduranya-deoxidation hamwe no gukuraho slag-atomisation na pulverisation-nziza-gutahura-gusuzuma-gupakira no kubika, ibikoresho byingenzi byakoreshejwe ni: itanura ryinjira hagati yumuriro, pompe yamazi yumuvuduko mwinshi, igikoresho gifunga pulverizing, ikigega cyamazi kizenguruka, ibikoresho byo gusuzuma no gupakira, ibikoresho byo gupima.
Inzira yagaze atomisiyasini nkibi bikurikira:
guhitamo ibyuma bitagira umwanda ibikoresho-bishonga mugihe giciriritse cyo kwinjiza itanura-ibice byo guhinduranya-deoxidation hamwe no gukuraho slag-atomisation na pulverisation-nziza-yerekana-kugenzura-gupakira no kubika. Ibikoresho by'ingenzi bikoreshwa ni: itanura ryo hagati ya firigo yo gushonga, isoko ya azote hamwe nigikoresho cya atome, ikigega cyamazi kizenguruka, ibikoresho byo gupima no gupakira, ibikoresho byo gupima. Buri buryo bugira ibyiza byabwo nibibi: Atomisiyasi yamazi ninzira nyamukuru yo gutembagaza, imikorere yayo myiza, umusaruro munini ni ubukungu, irashobora gutuma ifu iba nziza, ariko imiterere ntisanzwe, ifasha muburyo bwo kubungabunga, ariko binder yakoreshejwe byinshi, bigira ingaruka kubwukuri. Byongeye kandi, firime ya okiside ikorwa nigikorwa cyamazi nicyuma mubushyuhe bwinshi bibuza gucumura. Gazi Atomisiyonike nuburyo nyamukuru bwo gukora ifu yubuhanga bwo gutera inshinge. Ifu ikorwa na atomisiyasi ya gazi ni serefegitura, hamwe na dogere nkeya ya okiside, binder nkeya ikenewe kandi ikora neza, ariko umusaruro wifu ya ultra-nziza ni mike, igiciro ni kinini kandi imiterere ibika umutungo ni mibi, c, N, H, O muri binder bigira ingaruka kumubiri wacumuye. Ifu yakozwe nuburyo bwa karubone iri hejuru cyane, ituje mugitangiriro kandi nziza cyane mubunini. Birakwiriye cyane kuri MIM, ariko kuri Fe, Ni nandi mafu gusa, adashobora kuzuza ibisabwa byubwoko. Kugirango huzuzwe ibisabwa byifu kugirango ibumbwe mu byuma, ibigo byinshi byateje imbere uburyo bwavuzwe haruguru kandi biteza imbere micro-atomisation nuburyo bwa atomine ya laminari. Ubu mubisanzwe ni ifu ya atomize yifu na gaz atomize ifu ivanze ikoreshwa, iyambere kugirango izamure ubucucike bwimikorere, iyanyuma kugirango igumane imiterere. Kugeza ubu, gukoresha ifu ya atomize yamazi irashobora kandi kubyara umubiri wacumuye ufite ubucucike burenze 99%, bityo ifu ya atomizing yamazi niyo ikoreshwa mubice binini, naho ifu ya atomizing ya gaz ikoreshwa kubice bito. Mu myaka ibiri ishize, Handan Rand Atomizing Pulverizing Equipment Co., Ltd. yashyizeho ubwoko bushya bwibikoresho bya atomizing pulverizing, bidashobora gusa gutuma umusaruro munini w’amazi atome hamwe nifu ya ultrafine, ariko nanone uzirikana kuri ibyiza byuburyo bwa porojeri.
