Puas yog hlau txhaj tshuaj molding thiab yas txhaj tshuaj molding txawv? Yog muaj, qhov txawv yog dab tsi?

Hlau txhaj tshuaj molding (MIM) yog txheej txheem hlau ua haujlwm los ntawm cov hmoov hlau zoo sib xyaw nrog cov ntsuas ntsuas ntawm cov khoom siv los ua kom muaj "feedstock" muaj peev xwm ua tau los ntawm cov khoom siv yas los ntawm cov txheej txheem hu ua txhaj tshuaj molding. Cov txheej txheem molding tso cai rau dilated (oversized vim binder) complex qhov chaw kom zoo li tus nyob rau hauv ib kauj ruam thiab siab ntim. Tom qab molding, cov hmoov-binder sib tov yog raug rau cov kauj ruam uas tshem tawm cov binder (debinding) thiab sinter densify cov hmoov. Cov khoom kawg yog cov khoom me me siv hauv ntau yam kev lag luam thiab kev siv. Qhov xwm ntawm MIM feedstock flow yog txhais los ntawm lub cev hu ua rheology.

Tam sim no cov cuab yeej muaj peev xwm yuav tsum tau ua kom nyob twj ywm rau cov khoom uas tuaj yeem molded siv cov ntim ntawm 100 grams los yog tsawg dua rau ib "steev" rau hauv pwm. Rheology tso cai rau qhov "tshuaj tua" no tau muab faib rau ntau qhov kab noj hniav, yog li ua tus nqi zoo rau cov khoom me me, intricate, high-volume uas yuav tsis yog kim heev los tsim los ntawm lwm txoj kev los yog classic. Ntau yam ntawm cov hlau muaj peev xwm ua tau raws li MIM feedstock yog dav, tab sis feem ntau stainless hlau, xws li cov hmoov metallurgy; lawv muaj tib yam alloying constituents pom nyob rau hauv cov qauv kev lag luam. Txawm li cas los xij, cov pa oxygen feem ntau yog qhov nyuaj thiab feem ntau tsis tau teev tseg, tab sis tuaj yeem ua teeb meem rau kev tiv thaiv corrosion. Cov kev ua haujlwm txias tom qab tau ua rau ntawm cov duab molded, qhov twg cov ntaub ntawv khi tau raug tshem tawm thiab cov khoom hlau yog diffusion bonded thiab densified rau hauv lub xeev xav tau nrog feem ntau 15 feem pua ​​shrinkage nyob rau hauv txhua qhov ntev.

Cov hlau txhaj tshuaj molding kev lag luam tau nce los ntawm $ 9 lab USD hauv xyoo 1986, mus txog $ 382 lab USD hauv xyoo 2004 mus rau ntau tshaj $ 1.5 billion USD hauv 2015. Ib qho kev siv thev naus laus zis yog ceramic hmoov txhaj tshuaj molding, ua rau kwv yees li $ 2 billion USD tag nrho kev muag khoom. Feem ntau ntawm kev loj hlob nyob rau hauv xyoo tas los no yog nyob rau hauv Asia.

Txhaj tshuaj molding yog txheej txheem tsim khoom los ntawm kev txhaj tshuaj rau hauv pwm. Kev txhaj tshuaj molding tuaj yeem ua tau nrog cov khoom siv tshwj xeeb xws li hlau, (rau cov txheej txheem hu ua die-casting), iav, elastomers, confections, thiab feem ntau yog cov thermoplastic thiab thermosetting polymers. Cov khoom rau ib feem yog pub rau hauv ib lub thoob rhuab, sib tov, thiab yuam mus rau hauv lub pwm kab noj hniav, qhov twg nws txias thiab hardens rau configuration ntawm kab noj hniav.

Tom qab cov khoom tsim, feem ntau yog los ntawm tus tsim qauv lossis tus kws tsim qauv, pwm yog tsim los ntawm cov pwm tsim (los yog cov cuab yeej siv) los ntawm cov hlau, feem ntau yog hlau lossis txhuas, thiab precision-machined los tsim cov yam ntxwv ntawm qhov xav tau. Kev txhaj tshuaj molding yog dav siv rau kev tsim ntau yam, los ntawm cov khoom me tshaj plaws rau tag nrho lub cev ntawm lub tsheb. Kev nce qib hauv 3D tshuab luam ntawv, siv photopolymers uas tsis yaj thaum lub sij hawm txhaj tshuaj molding ntawm qee qhov kub ntawm cov thermoplastics, tuaj yeem siv rau qee cov pwm txhaj tshuaj yooj yim.

Cov khoom yuav tsum tau txhaj tshuaj molding yuav tsum tau ua tib zoo tsim los pab txhawb cov txheej txheem molding; cov khoom siv rau ib feem, qhov xav tau cov duab thiab cov yam ntxwv ntawm ib feem, cov khoom ntawm cov pwm, thiab cov khoom ntawm lub tshuab molding yuav tsum muab tag nrho rau hauv tus account. Lub versatility ntawm kev txhaj tshuaj molding yog yooj yim los ntawm qhov dav ntawm qhov kev txiav txim siab tsim thiab muaj peev xwm.
