Nyob rau hauv xyoo tas los no, lubmicro-metal txhaj molding txheej txheem (μ-MIM) tau tsim nrog lub hom phiaj ntawm kev tsim cov hlau thiab alloys uas tuaj yeem siv rau kev tsim khoom loj ntawm micro-qhov chaw thiab micro-structure nto. μ-MIM ua kom muaj cov hlau thiab alloys rau micro-daim ntawv thov, xws li cov ntaub ntawv tshiab nrog kub stability, lub zog thiab toughness, nrog rau thermal conductivity thiab magnetism.

Tsis tas li ntawd, piv nrog cov yas micro-txhaj tshuaj molding, cov txheej txheem tsim bimetal tsim los ntawm μ-MIM ua rau ob qho khoom siv hlau sib txuas ua ke (bimetal co-injection) thaum lub sijhawm txhaj tshuaj molding.

1. Ob-Component MIM (2C-MIM)

Qhov saum npoo yog ntxeem tau thiab lub hauv paus tseem ceeb yog ntom

Raws li ib txoj kev ntawm kev tsim khoom bimetallic, tib neeg tau tsim cov txheej txheem 2C-MIM (Ob-Component MIM). Lub ntsiab kom zoo dua ntawm cov txheej txheem 2C-MIM yog tias ob cov ntaub ntawv uas muaj cov khoom sib txawv tuaj yeem ua ke ncaj qha rau hauv ib qho kev tsim khoom, yog li txo qis kev sib koom ua ke tom qab (xws li vuam, riveting, fastening sib dhos, thiab lwm yam).

Cov khoom uas 2C-MIM tuaj yeem tsim tau ntau yam los ntawm qhov hollow nrog cov txheej txheem sab hauv kom hloov tau yooj yim detachable Cheebtsam.

Lub hom phiaj ntawm tag nrho cov kev tshawb fawb yog tsim kom muaj kev txhim kho engineering qhov chaw ntawm tus nqi zoo. Rau qhov chaw uas yooj yim rau hnav, koj tuaj yeem tsuas yog hauv zos ntxiv dag zog rau qhov tseem ceeb xws li kev sib txhuam nto nrog cov khoom siv tawv los yog ntau dua hnav, thiab lwm yam khoom siv nrog cov khoom siv qis.

Txhawm rau tsim cov khoom siv bimetal, tsuas yog nkag siab txog kev txhaj tshuaj molding zoo ntawm ob cov ntaub ntawv txhaj tshuaj tsis txaus, qhov tseem ceeb yog tias ob cov ntaub ntawv yuav tsum muaj peev xwm ua tau sintered nyob rau hauv tib lub cub tawg thiab nyob rau hauv tib sintering cua. Vim tias qhov shrinkage tus nqi ntawm ob qhov chaw tsis zoo ib yam thaum lub sij hawm sintering, nws yuav ua rau delamination los yog tawg. Thiab thaum lub sij hawm tsim kev puas tsuaj, cov ntsiab lus alloyed tseem tuaj yeem kis tau raws tus ciam teb, uas txo cov khoom ntawm cov khoom.

Los ntawm kev sib koom tes ntawm machining yam, qhov zoo ntawm 2C-MIM qhov chaw yog optimized. Vim nws lub peev xwm tshwj xeeb los ua ib feem nrog cov khoom sib txawv yam tsis muaj kev sib dhos ua haujlwm, cov txheej txheem 2C-MIM yog qhov tseeb kom nthuav dav daim ntawv thov kev lag luam ntawm MIM kev lag luam.

Yog hais tias qhov luaj li cas ntawm cov hmoov yog qis dua 1um, cov ntaub ntawv tshwj xeeb yuav tsum tau siv los hloov kho cov teeb meem tshwm sim los ntawm qhov loj ntawm qhov chawhmoov txhaj molding thiab degreasing.

2.Micro Hlau Txhaj Moulding Txheej Txheem (μ-MIM)

Microinjection stainless hlau tshuaj tiv thaiv phaj

Cov khoom lag luam thiab cov tshuab tau dhau los ua qhov me me, uas txhais tau hais tias cov qauv thiab kev ua haujlwm hauv cov tshuab ua haujlwm tau dhau los ua me thiab me.

Qhov no yuav tsum tsis yog tsuas yog siv cov khoom siv siab heev nrog cov khoom tsim nyog lub cev, tab sis kuj tseem muaj cov yam ntxwv ntawm micro-miniaturized geometric txhawm rau txhawm rau ua kom muaj cov haujlwm sib xyaw ua ke.

Yog li ntawd, nws yog ib qho tsim nyog los tsim cov txheej txheem ua tau zoo thiab txhim khu kev qha rau kev tsim cov khoom me me lossis cov khoom siv me me, thiab cov khoom siv micro-cov qauv tsim nrog μ-MIM tuaj yeem siv los hloov cov khoom yas kom tau txais qhov zoo ntawm cov khoom siv kho tshuab, corrosion kuj. los yog kub siab ntawm cov khoom siv hlau.

Kev ua tiav ntawm cov txheej txheem tsim khoom tshiab no yog nyob ntawm qhov tseeb tias nws cov txheej txheem kev sib tw yog txwv los ntawm cov khoom siv los yog cov peev txheej ntau lawm, thiab tsis muaj lwm txoj hauv kev rau μ-MIM.

LIGA thev naus laus zis (kev sib xyaw ntawm lithography thiab electroforming) feem ntau tsuas yog tsim nyog rau 2D geometry, thiab tsuas yog txwv los ntawm electroforming raws li cov khoom xaiv.

Lwm cov txheej txheem, xws li electrochemical micro-manufacturing txoj kev, micro-milling thiab micro-sib tsoo, tuaj ntawm silicon-based microelectronics kev lag luam thiab muaj peev xwm los daws cov yam ntxwv me me li 1μm, tab sis lawv tsis haum rau cov khoom loj ntawm3D qhov chaw.

Tam sim no, micro qhov chaw tsim nrog μ-MIM tuaj yeem ua me me li 5μm hauv qhov loj me. Txawm li cas los xij, txhawm rau txhawm rau txhim kho kev ua tau zoo, xws li tswj cov duab raws li cov yam ntxwv ntws los yog qhov chaw, cov ntaub ntawv tshwj xeeb txhaj tshuaj tau tsim kom muaj peev xwm ua tau rau cov submicron lossis nanometer xav tau rau μ-MIM.

Feem ntau, rau cov khoom me me, MIM tuaj yeem rov ua cov yam ntxwv ntawm li 10 npaug ntawm qhov nruab nrab particle loj, uas yog tshwj xeeb tshaj yog haum rau micro qhov chaw, yog tias koj xav tsim cov yam ntxwv me me, koj yuav tsum tau siv cov hmoov me me. Tam sim no, cov hmoov hlau muaj yog 1μm. Qee cov hmoov muaj zog heev los tsim cov hmoov hauv cov khoom me me (piv txwv li, Ti), thaum lwm cov hmoov hlau yog yooj yim dua los tsim nrog tshwj xeeb aerosol vaporization (xws li, stainless hlau).

Yog tias qhov loj me ntawm cov hmoov yog qis dua 1um, cov ntaub ntawv tshwj xeeb yuav tsum tau siv los hloov kho cov teeb meem tshwm sim los ntawm qhov loj ntawm thaj tsam ntawm cov hmoov txhaj tshuaj molding thiab degreasing.

Tam sim no, μ-MIM tseem nyob rau theem incubation thiab loj hlob nyob rau hauv parallel nrog 2C-MIM txheej txheem. Ua ntej, ob qho tib si cov txheej txheem tam sim no nyob rau hauv kev tsim khoom, tab sis ob qho tib si tab tom ua cov txheej txheem thev naus laus zis thiab kev tshawb fawb txog kev ua tau zoo rau ntau yam ntawm micro-qhov lossis micro-structural qhov chaw.

Kev tshawb nrhiav kev sib tw thiab kev tsim kho lub hom phiaj tseem ceeb ntawm lawv txoj hauv kev mus rau kev ua lag luam kev vam meej, tab sis tsuas yog los ntawm kev txhim kho cov ntaub ntawv thiab cov txheej txheem ntau lawm nyob ib ncig ntawm qhov muaj peev xwm ntawm 2C-μ-MIM hauv kev lag luam, ua ke nrog kev kawm ntawm cov engineers thiab cov kws tshaj lij, tuaj yeem ua tau tiag tiag. ua tiav.

Hauv rau lub hlis dhau los, nrog rau daim ntawv thov ntawm ceramic thiab 3D iav hauv cov xov tooj ntawm tes tau txais kev saib xyuas ntau thiab ntau dua, kuj tseem muaj ntau lub iav ob sab 3D thiab cov qauv ceramic. Ntau thiab ntau lub tuam txhab muaj qhov kev lag luam no, qhia txog kev vam meej ntawm ib puas paj, qee cov thev naus laus zis tshiab, cov txheej txheem tshiab, cov ntaub ntawv tshiab tau tsim, xws li: stainless hlau, titanium alloy, MIM thav duab, ceramic back cover, txheej txheem xws li, iav kho kom zoo nkauj txheej txheem kev ntxhib los mos txoj kev loj hlob, number case spray txheej txheem tshiab, luam ntawv thiab kav hlau txais xov fusion; Yuav ua li cas txhawm rau txhim kho 3D iav hla tus nqi, txo kev siv zog, thiab txhim kho kev ua haujlwm tau dhau los ua teeb meem nyuaj rau tag nrho kev lag luam.
