Inkqubo ye-MIM (isitofu sentsimbi)., oluluhlobo olutsha lwenxalenye yentsimbi yokwenza inkqubo edibanisa inkqubo yokubumba inaliti yeplastiki yanamhlanje kunyeinkqubo yesinyithi engumgubo. Le nkqubo intsha yavela ekupheleni kweminyaka yoo-1970 kwaye ekuqaleni yayisetyenziselwa ukwenza izixhobo ezilula. Ngeli xesha ndiza kwazisa ezininziAmalungu okubumba inaliti yentsimbi ye-MIMngezixhobo.
I-JIEHUANG CHIYANG Inkampani ephezulu yokubumba inaliti yentsimbi:
Amalungu okuqala e-MIM: Ukupakishwa kwe-Electronic amalungu eMIM. Le nxalenye yenziwa nguIteknoloji yeMIM (Metal Injection Molding).ize yenziwe ngamacandelo ebakala le-F15 (Ni-Co-Fe); ukunyamezelana komngxuma kukudibanisa okanye uthabathe i-0.2mm. Le mveliso yokubumba inaliti yesinyithi isetyenziselwa ukupakishwa kwe-Opto-electronic. Enye yeemfuno kukuba i-curve yokwandiswa kwezinto kufuneka ifane neglasi evaliweyo.
Ugxininiso lomthengi kukuvavanya ukusebenza kokutywinwa kwendawo ebiyelweyo ye-MIM yombane emva kokuba iinxalenye ziphantsi komothuko we-thermal. Le nxalenye ithatha indawo yeemveliso ezenziwe ngokusika kunye nokuqhaqha. Amalungu e-MIM anokunciphisa kakhulu iindleko zemveliso kunamalungu enziwe ngokusika.
Amacandelo e-MIM YESIBINI: Ukunyamezela kwe-dimensional yomshini wokubumba umatshini we-injection yensimbi engenasici yesixhobo sombono wangemva we-rifle yi-0.5%. Isixhobo sokutofa esisetyenzisiweyo sisibophelelo se-thermoplastic kunye ne-iron-7% ye-nickel alloy. Ubuninzi bomzimba we-sintered bufikelela kwi-7.82 nge-square centimeter. Iimpawu zomatshini ezichazwe kwiimeko zobugcisa zezi: amandla okuqina 430MPa, amandla emveliso angama-295MPa, ubunzima be-55HRC (emva kokungcwatywa kunye nokucima), kunye ne-modulus ye-elasticity 203GPa.
Le nxalenye yenziwe yi inkqubo yokubumba inaliti yentsimbiyaveliswa ngaphambili ngokusikwa. Ngokujonga ubume obunzima benxalenye kunye nemingxuma ebekwe kwiindlela ezahlukeneyo, ukusika kuyabiza. Isixhobo sombono wasebusuku sisetyenziselwa umpu we-M-6. Ngenxa yokusetyenziswa kwenkqubo yeMIM, ixabiso leengxenye lingancitshiswa ngama-60%. Ngaphandle kwe-carburizing kunye nokucima, akukho nyango lwangaphandle olufunekayo.
Iinxalenye zezixhobo eziveliswe ziinxalenye zenkqubo yokwenziwa kweMIM 2
