MIM (icyuma cyo gutera inshinge) inzira, ni ubwoko bushya bwicyuma kigizwe nuburyo bwo guhuza uburyo bugezweho bwo gutera inshinge naifu yicyuma. Ubu buryo bushya bwagaragaye mu mpera za za 70 kandi mu ntangiriro bwakoreshwaga cyane mu gukora ibice by’intwaro zoroheje. Iki gihe nzatangiza byinshiIbice byo guteramo ibyuma bya MIMy'intwaro.
JIEHUANG CHIYANG Isosiyete ikora imashini ikora inshinge:
Ibice bya mbere bya MIM: Ibikoresho bya elegitoroniki bipakira MIM ibice. Iki gice cyakozwe naIkoranabuhanga rya MIM (Metal Injection Molding)kandi bigizwe nibice bya F15 (Ni-Co-Fe); kwihanganira umwobo ni plus cyangwa gukuramo 0.2mm. Iki gikoresho cyo guteramo ibyuma gikoreshwa mugupakira Opto-elegitoroniki. Kimwe mu bisabwa ni uko kwagura umurongo wibikoresho bigomba kuba bisa nibirahuri bifunze.
Umukiriya yibanze ku kugerageza imikorere yikimenyetso cya MIM ya elegitoroniki nyuma yuko ibice byibasiwe nubushyuhe. Iki gice gisimbuza ibicuruzwa byakozwe mugukata no gushakisha. Ibice bya MIM birashobora kugabanya cyane ibiciro byumusaruro kuruta ibice byakozwe mugukata.
Ibice bya kabiri bya MIM: Kwihanganira ibipimo byimashini itera inshinge ibyuma bidafite ibyuma byimbunda yinyuma nijoro ni 0.5%. Ibikoresho byo gutera inshinge zikoreshwa ni bingo ya thermoplastique hamwe nicyuma-7% nikel. Ubucucike bwumubiri wacumuye bugera kuri 7.82 kuri santimetero kare. Imiterere yubukanishi bwerekanwe mubihe bya tekiniki ni: imbaraga zingana 430MPa, imbaraga zitanga 295MPa, ubukana 55HRC (nyuma yo gutwika no kuzimya), hamwe na modulus ya elastique 203GPa.
Iki gice cyakozwe na kwigana ibyuma byo gutera inshingembere yakozwe mugukata. Urebye imiterere igoye yigice hamwe nu mwobo uherereye mu byerekezo bitandukanye, gukata bihenze. Igikoresho cyo kureba nijoro gikoreshwa ku mbunda ya M-6. Bitewe no gukoresha inzira ya MIM, igiciro cyibice gishobora kugabanukaho 60%. Usibye carburizing no kuzimya, nta kuvura hejuru bisabwa.
