M'zaka zaposachedwapa, aNjira yopangira jakisoni wachitsulo (μ-MIM)yapangidwa ndi cholinga chopanga zitsulo ndi ma alloys omwe angagwiritsidwe ntchito popanga misampha ya tinthu tating'onoting'ono komanso tating'ono tating'ono. μ-MIM imachulukitsa kwambiri kupezeka kwa zitsulo ndi ma aloyi azinthu zazing'ono, monga zida zatsopano zokhazikika kutentha, mphamvu ndi kulimba, komanso matenthedwe matenthedwe ndi maginito.

Komanso, poyerekeza ndi pulasitiki yaying'ono jekeseni akamaumba, bimetal kupanga ndondomeko yopangidwa ndi μ-MIM zimathandiza kuti zipangizo ziwiri zitsulo zosiyanasiyana kugwirizana pamodzi (bimetal co-jekeseni) pa jekeseni akamaumba ndondomeko.

1. Zigawo ziwiri MIM (2C-MIM)

Pamwamba pake ndi porous ndipo mkati mwake ndi wandiweyani

Monga njira yopangira magawo a bimetallic, anthu apanga njira ya 2C-MIM (Two-Component MIM). Ubwino waukulu wa ndondomeko ya 2C-MIM ndikuti zipangizo ziwiri zomwe zili ndi katundu wosiyana zimatha kuphatikizidwa mwachindunji mu ndondomeko imodzi yopangira, motero kuchepetsa ntchito zophatikizana zotsatizana (monga kuwotcherera, riveting, kumangiriza msonkhano, etc.).

Ziwalo zomwe 2C-MIM imatha kupanga kuchokera pazigawo zopanda kanthu zokhala ndi zovuta zamkati mpaka zosinthika zosinthika.

Cholinga cha kafukufuku wonse ndikupanga zida zamainjiniya zokhazikika pamtengo wabwino. Pazigawo zomwe zimakhala zosavuta kuvala, mungathe kulimbikitsa zigawo zazikuluzikulu kwanuko monga kugwedezeka pamwamba ndi zida zolimba kapena zosavala, ndi zina zomangira zomwe zili ndi zipangizo zotsika mtengo.

Kupanga zigawo za bimetal, kungomvetsetsa mawonekedwe a jekeseni wa zida ziwiri za jekeseni sikokwanira, chinsinsi ndi chakuti zipangizo ziwirizi ziyenera kutenthedwa mu ng'anjo yomweyi komanso mumlengalenga womwewo wa sintering. Chifukwa kuchuluka kwa shrinkage kwa magawo awiriwa sikufanana panthawi ya sintering, kungayambitse delamination kapena kusweka. Ndipo pamene gawo lovulaza lipangidwa, zinthu zowonongeka zimatha kufalikiranso pamalire, zomwe zimachepetsa katundu wa zinthuzo.

Chithunzi cha 17-4PH / 316L chophatikizika chokhazikika chokonzekera ndi jekeseni

Mwa kugwirizanitsa zinthu zamakina, mtundu wa magawo a 2C-MIM umakongoletsedwa. Chifukwa cha luso lake lapadera lopanga gawo ndi zinthu zosiyanasiyana zakuthupi popanda ntchito yapagulu, njira ya 2C-MIM ndiyotsimikizika kukulitsa msika wogwiritsa ntchito. Makampani a MIM.

Ngati tinthu tating'onoting'ono ta ufa ndi pansi pa 1um, zida zapadera za jakisoni ziyenera kugwiritsidwa ntchito kuti zigwirizane ndi zovuta zomwe zimayambitsidwa ndi gawo lalikulu laufa jekeseni akamaumba ndi kuchepetsa mafuta.

2.Micro Metal Injection Molding Process (μ-MIM)

Microinjection Stainless steel reaction mbale

Zogulitsa ndi machitidwe akukhala ocheperako, zomwe zikutanthauza kuti zida zamapangidwe ndi zogwirira ntchito m'makina ovuta zikukhala zing'onozing'ono.

Izi zimafuna osati kugwiritsa ntchito zipangizo zamakono zomwe zili ndi thupi loyenera, komanso mawonekedwe a geometric micro-miniaturized kuti awonjezere chiwerengero cha ntchito zophatikizika.

Chifukwa chake, ndikofunikira kupanga njira zodalirika komanso zodalirika zopangira magawo ang'onoang'ono kapena magawo ang'onoang'ono, ndipo magawo ang'onoang'ono opangidwa ndi μ-MIM angagwiritsidwe ntchito m'malo mwa zigawo zapulasitiki kuti apeze zabwino zamakina, kukana dzimbiri kapena kutentha kwazinthu zachitsulo.

Kupambana kwa njira yatsopanoyi yopangira zinthu kumachokera ku mfundo yakuti mpikisano wake umachepa ndi zipangizo zogwiritsira ntchito makina kapena mphamvu zopangira misala, ndipo palibe njira ina μ-MIM.

Tekinoloje ya LIGA (kuphatikiza kwa lithography ndi electroforming) nthawi zambiri imakhala yoyenera pa 2D geometry, ndipo imachepetsedwa ndi electroforming posankha zinthu.

Njira zina, monga njira zopangira ma electrochemical micro-manufacturing, mphero yaying'ono ndi kugaya yaying'ono, zimachokera kumakampani opanga ma silicon-based microelectronics ndipo amatha kuthana ndi zinthu zazing'ono ngati 1μm, koma sizoyenera kupanga zambiri.Zithunzi za 3D.

Tsopano, magawo ang'onoang'ono opangidwa ndi μ-MIM amatha kukhala ochepa ngati 5μm kukula kwake. Komabe, kuti muwongolere magwiridwe antchito, monga kusunga mawonekedwe molingana ndi mawonekedwe oyenda kapena magawo, zida zapadera za jakisoni zapangidwa zomwe zingatheke kwathunthu kwa submicron kapena nanometer yofunikira kwa μ-MIM.

Nthawi zambiri, pazigawo zazing'ono, MIM imatha kubwereza mawonekedwe pafupifupi 10 kuchuluka kwa tinthu tating'onoting'ono, komwe ndi koyenera kumagulu ang'onoang'ono, ngati mukufuna kupanga mawonekedwe ang'onoang'ono, muyenera kugwiritsa ntchito ufa wocheperako. Tsopano, ufa wachitsulo womwe ulipo ndi 1μm. Ena ufa kwambiri zotakataka kutulutsa ufa mu tinthu kukula osiyanasiyana (mwachitsanzo, Ti), pamene ena zitsulo ufa ndi zosavuta kupanga ndi wapadera aerosol vaporization (mwachitsanzo, zosapanga dzimbiri).

Ngati tinthu kukula osiyanasiyana ufa ndi pansipa 1um, zipangizo jekeseni wapadera ayenera kugwiritsidwa ntchito kuti agwirizane ndi mavuto aakulu padziko lonse la ufa jekeseni akamaumba ndi degreasing.

Chithunzi cha microinjection zosapanga dzimbiri giya ndi chotuluka

Pakali pano, μ-MIM idakali mu siteji ya incubation ndipo ikukula kwambiri mofanana ndi ndondomeko ya 2C-MIM. Choyamba, njira zonse ziwirizi zikupangidwa, koma zonse zikuyendetsedwa ndiukadaulo komanso maphunziro otheka a magawo ang'onoang'ono kapena ma microstructural.

Zolinga zoyambira zampikisano komanso zachitukuko ndizofunikira kwambiri panjira yopita ku msika wopambana, koma pokhapokha popanga zida ndi njira zopangira mozungulira kuthekera kwa 2C-μ-MIM mumakampani, kuphatikiza maphunziro a mainjiniya ndi amisiri, zopambana zenizeni zingatheke.

M'miyezi isanu ndi umodzi yapitayo, ndikugwiritsa ntchito magalasi a ceramic ndi 3D m'mafoni am'manja akupeza chidwi kwambiri, palinso mitundu yambiri ya magalasi a 3D okhala ndi mbali ziwiri ndi mawonekedwe a ceramic. Mabizinesi ochulukirachulukira ali ndi makampaniwa, akuwonetsa kukula kwa maluwa zana, umisiri wina watsopano, njira zatsopano, zida zatsopano zapangidwa, monga: chitsulo chosapanga dzimbiri, aloyi ya titaniyamu, chimango cha MIM, chivundikiro chakumbuyo cha ceramic, mbali za njira monga, kukonza magalasi okongoletsa kapangidwe kake, kutsitsi kwa inkino njira yatsopano, kusindikiza ndi kuphatikizika kwa mlongoti; Momwe mungasinthire kuchuluka kwa magalasi a 3D, kuchepetsa kugwiritsa ntchito mphamvu, komanso kukonza bwino kwakhala vuto lalikulu pamakampani onse.
