Nrog rau kev txhim kho tas mus li ntawm kev lag luam niaj hnub, cov txheej txheem ua haujlwm ib txwm tsis tuaj yeem ua tau raws li cov kev xav tau ntawm cov khoom siv niaj hnub no, thiab ntau cov qauv tsim tshwj xeeb yog qhov nyuaj lossis tsis tuaj yeem ua los ntawm kev ua ib txwm ua. Yog li ntawd, 3D tshuab luam ntawv tau los ua. Hauv kev tsim cov khoom lag luam ib txwm muaj, cov pwm feem ntau qhib ua ntej, thiab tom qab ntawd tus qauv tsim. Txawm li cas los xij, kev siv thev naus laus zis 3D tsis tas yuav qhib pwm, uas ua txhaum los ntawm cov qauv tsim ib txwm muaj, thiab tuaj yeem txuag lub sijhawm tsim khoom, txo cov nqi, thiab tswj cov nqi khiav lag luam zoo dua. 3D luam ntawv yog ib qho kev siv technology tshiab hauv kev tsim khoom. Nws txoj kev loj hlob sai yog nyob rau hauv tag nrho viav vias, thiab nws tau nyiam thoob plaws hauv tsev thiab txawv teb chaws. Nws yog hu ua "manufacturing technology with industrial revolution significance".
Cov txheej txheem PEP muaj ntau yam zoo sib xws nrog cov hmoov txhaj tshuaj molding. Nws siv cov hmoov sib tov los ua cov ntaub ntawv granular thiab npaj lub cev ntsuab nrog qee qhov ceev thiab lub zog los ntawm 3D luam ntawv ntawm lub tshuab extrusion. Tom qab degreasing thiab sintering, qhov kawg compact ntawm tiav pieces. Piv nrog rau cov tshuab luam ntawv ncaj qha 3D uas siv lub zog siv hluav taws xob siab sintering lossis melting hlau thiab lwm yam ntaub ntawv kom tau txais cov duab thiab kev ua tau zoo ntawm cov khoom, PEP tau txais cov duab thiab kev ua tau zoo ntawm cov khoom kauj ruam: qauv tsim → 3D luam ntawv → degreasing thiab sintering → khoom tiav.
Nws innovatively siv 3D luam ntawv kom paub txog kev tswj thiab molding ntawm cov ntaub ntawv thiab paub moldless qauv npaj, uas yuav ua tau raws li cov neeg siv cov customization xav tau kev pab rau hlau / ceramic qhov chaw. Nyob rau tib lub sijhawm, kev hloov pauv ntawm cov txheej txheem thermal ua cov kauj ruam mus rau sintering kauj ruam ua rau nws yooj yim dua los tswj cov kev ntxhov siab thermal. Vim tias qhov kub ntawm sintering yog qis dua qhov kub melting tag nrho uas yuav tsum tau ua hauv lwm hom kev luam ntawv ncaj qha 3D, thiab cov cua sov tuaj yeem siv tau ntau dua, qhov no ua kom cov khoom zoo ib yam.
Lub ntsiab zoo ntawm PEP technology:
1. Nws muaj cov yam ntxwv ntawm qhov kub thiab txias sib sau ua haujlwm siab thiab tuaj yeem paub txog kev npaj cov khoom siv theoretical siab tshaj plaws.
2. Cov txheej txheem tsim yog yooj yim, tsis muaj cov khoom siv laser xav tau, thiab cov peev txheej thiab cov nqi kho mob kuj tsawg.
3. Kev ua haujlwm yog yooj yim, thiab lub hauv paus ntsiab lus ntawm cov qauv tsim yog yooj yim to taub, uas yog qhov tsim nyog rau kev nce qib thiab nrov ntawm 3D luam ntawv daim ntawv thov.
4. Cov cuab yeej siv siab tshaj plaws, 3D tshuab luam ntawv txais kev ywj pheej ob lub nozzle tsim, uas tuaj yeem paub txog kev txhim kho sai ntawm cov khoom siv hlau / ceramic.
5. Cov txheej txheem kev paub tab thiab ruaj khov ntawm cov hmoov txhaj tshuaj molding (PIM) tuaj yeem siv los ua kom paub txog tus kheej, kev txawj ntse, thiab kev sib raug zoo ntawm kev tsim khoom, thiab ua tau raws li cov txheej txheem ntau dua thiab cov ntawv thov.
6. Cov khoom siv luam ntawv nplua nuj, suav nrog tab sis tsis txwv rau cov khoom siv hmoov siv hauv cov txheej txheem PIM.
7. Muaj zog sib raug zoo, tuaj yeem hloov kho rau kev tsim cov khoom siv hlau thiab cov khoom siv ceramic, thiab muaj peev xwm ua tiav ntau yam ntawm cov khoom siv siab heev.
8. Ntsuab thiab ib puag ncig tus phooj ywg, lub cev ntsuab tuaj yeem rov ua dua thiab rov ua dua tshiab, nrog rau kev siv tau zoo, thiab ua raws li txoj hauv kev ntawm kev txhim kho kom ruaj khov.
