Metal Injection Molding (MIM) ndi mtundu watsopano waukadaulo wa Powder metallurgy, womwe umapangidwa kuchokera ku jekeseni wa ufa (PIM) wa zida za ceramic. Njira zazikulu zopangira Metal jekeseni Woumba ndi motere: kusakaniza zitsulo ufa ndi binder-granulation-jekeseni akamaumba-degreasing-sintering-wotsatira mankhwala-chomaliza mankhwala, luso ndi oyenera yaing'ono, zovuta, mkulu-ntchito misa kupanga ufa zitsulo. zigawo, monga zomwe zimagwiritsidwa ntchito ndi makampani owonera mawotchi aku Swiss kupanga mawotchi. Zaka makumi angapo zapitazi, ukadaulo wa MIM wakula mwachangu, zida zomwe zimagwiritsidwa ntchito ndi izi: Fe-Ni aloyi, chitsulo chosapanga dzimbiri, chitsulo chachitsulo, aloyi yapamwamba yokoka, simenti ya carbide, aloyi ya titaniyamu, ni-based superalloy, intermetallic pawiri, alumina, zirconia ndi zina zotero. pa. Tekinoloje ya Metal Injection Molding (MIM) imafuna kuti kukula kwa tinthu ting'onoting'ono kwa ufa ndi kocheperako kuposa micron ndipo mawonekedwe ake ndi pafupifupi ozungulira. Komanso, kachulukidwe lotayirira, kachulukidwe kugwedera, chiŵerengero cha kutalika kwa m'mimba mwake, masoka otsetsereka ngodya ndi tinthu kukula kugawa nawonso chofunika. Pakali pano, njira zazikulu zopangira ufa waukadaulo wopangira jakisoni wazitsulo ndi atomization yamadzi, atomization yamafuta ndi njira yamagulu a carbonyl. The ambiri ntchito zopangidwa ufa jekeseni wa zitsulo zosapanga dzimbiri ndi: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, etc. Njira ya atomization yamadzi ili motere: kusankhidwa kwa chitsulo chosapanga dzimbiri-kusungunuka mu ng'anjo yapakatikati-kuphatikiza kusintha-deoxidation ndi slag kuchotsa-atomization ndi pulverization-quality discovering-screening-packages, zipangizo zazikulu zomwe zimagwiritsidwa ntchito ndi: ng'anjo yapakatikati, pampu yamadzi yothamanga kwambiri, chipangizo chotsekera chotsekedwa, thanki yamadzi yozungulira, zida zowunikira ndi zonyamula, zida zoyesera.

Ndondomeko yagasi atomizationndi motere:

Kusankha zitsulo zosapanga dzimbiri-kusungunuka mu ng'anjo yapakatikati yopangira ng'anjo-kupanga kusintha-deoxidation ndi slag kuchotsa-atomization ndi pulverization-quality kuzindikira-kuwunika-kuyika ndi kusunga. Zida zazikulu zomwe zimagwiritsidwa ntchito ndi: ng'anjo yapakatikati yosungunuka, gwero la nayitrogeni ndi chipangizo cha atomization, thanki yamadzi yozungulira, zida zowunikira ndi zonyamula, zida zoyesera. Njira iliyonse ili ndi ubwino ndi zovuta zake: Atomization yamadzi ndiyo njira yaikulu yopukutira, mphamvu zake zazikulu, kupanga kwakukulu kumakhala kopanda ndalama, kungapangitse ufa wabwino, koma mawonekedwe ake ndi osakhazikika, omwe amathandiza kuti asungidwe, koma Binder ntchito kwambiri, zimakhudza kulondola. Komanso, makutidwe ndi okosijeni filimu yopangidwa ndi mmene madzi ndi zitsulo pa kutentha kumalepheretsa sintering. Gasi Atomization ndiye njira yayikulu yopangira ufa waukadaulo wopangira jakisoni wazitsulo. Ufa wopangidwa ndi mpweya wa atomization ndi wozungulira, wokhala ndi digirii yotsika ya okosijeni, womangirira wocheperako komanso mawonekedwe abwino, koma zokolola za ufa wapamwamba kwambiri ndizotsika, mtengo wake ndi wokwera komanso mawonekedwe osunga mawonekedwe ndi osauka, c, N, H, O mu binder amakhudza thupi la sintered. Ufa wopangidwa ndi njira ya carbonyl ndi wachiyero kwambiri, wokhazikika pachiyambi komanso wabwino kwambiri mu kukula kwa tinthu. Ndizoyenera kwambiri kwa MIM, koma kwa Fe, Ni ndi ufa wina, womwe sungathe kukwaniritsa zofunikira za mitundu. Pofuna kukwaniritsa zofunikira za ufa wopangira jekeseni wazitsulo, makampani ambiri asintha njira zomwe zili pamwambazi ndikupanga njira za micro-atomization ndi laminar atomization. Tsopano ndi madzi atomized ufa ndi mpweya atomized ufa wothira ntchito, woyamba kusintha kachulukidwe wa compaction, chotsirizira kukhalabe mawonekedwe. Pakalipano, kugwiritsa ntchito madzi atomizing ufa kungathenso kupanga sintered thupi ndi kachulukidwe wachibale kuposa 99% , kotero madzi atomizing ufa ntchito mbali zikuluzikulu, ndi mpweya atomizing ufa ntchito mbali zing'onozing'ono. M'zaka ziwiri zapitazi, Handan Rand Atomizing Pulverizing Equipment Co., Ltd. yapanga mtundu watsopano wa zida za atomizing pulverizing, zomwe sizingatsimikizire kupanga kwakukulu kwa madzi atomizing ndi ufa wa ultrafine, komanso kuganizira ubwino wa mawonekedwe a ufa wozungulira.
