Ceramic tau dhau los ua cov khoom ntawm kev xaiv rau cov ntse hnav vim nws khawb-pov thawj, tawv nqaij-phooj ywg, tsis ua xua, jade xim thiab tus nqi qis. Thiab ceramic txhaj tshuaj molding yog ib qho ntawm cov txheej txheem molding tseem ceeb ntawm cov khoom siv zoo nkauj zoo nkauj ceramic.
Ceramic txhaj tshuaj molding txheej txheem
Ceramic txhaj tshuaj moldingyog ib qho ze ntawm qhov loj me me yas molding txoj kev tsim los ntawm lub hauv paus ntawm polymer txhaj tshuaj molding tshuab. Cov txheej txheem yooj yim ntawm kev txawj ntse hnav cov ceramic txhaj tshuaj feem ntau suav nrog plaub theem: kev npaj pub noj, txhaj tshuaj molding, degreasing thiab sintering.
1. Pub kev npaj Lub yttrium stabilized zirconia hmoov thiab surfactant yog hnyav nyob rau hauv kev faib ua feem, ethanol yog ntxiv, ces tov los ntawm pob milling, qhuav thiab tshuaj ntsuam kom tau slurry, thiab ces tov nrog binder, tov thiab granulated kom tau pub rau txhaj tshuaj.
Qhov tseem ceeb rau kev npaj pub mis:
Xaiv qhov tsim nyog binder, binder thiab ceramic hmoov compatibility thiab shear dispersion zoo, tshem tawm agglomeration;
Cov ntsiab lus binder tsim nyog, kom cov khoom noj muaj fluidity zoo;
Ua kom cov hmoov ceramic ntxiv loading (cov ntsiab lus khoom) thiab txo qhov deformation.
2, kev txhaj tshuaj molding yuav tsum tau txhaj tshuaj molding pub muab tso rau hauv lub tshuab txhaj tshuaj molding, rhuab mus rau hauv cov kua nplaum nplaum, ntawm qhov kub thiab txias siab ceev txhaj rau hauv cov pwm hlau, txias tom qab stripping tawm kom tau lub cev ceramic. Qhov tseem ceeb ntawm kev txhaj tshuaj molding:
Tsim nyog pwm tsim thiab ua haujlwm ( rooj vag, khiav, precision, khoom, thiab lwm yam)
Kev teeb tsa thiab optimization ntawm kev txhaj tshuaj tsis haum (kub, siab, pwm kub)
Tso pa tawm thiab lub cev kev ntxhov siab thaum lub sij hawm pwm filling
3, degreasing degreasing yog cov txheej txheem ntawm kev tshem tawm cov binder tivthaiv hauv kev txhaj tshuaj molding ceramic billet los ntawm kev siv lub cev lossis tshuaj. Vim yog cov txheej txheem sib txawv, cov txheej txheem degreasing txawv, kev txhaj tshuaj molding ceramic degreasing txoj kev suav nrog: thermal degreasing, hnyav degreasing, catalytic degreasing, xaiv cov cuab yeej zoo thiab kev nyab xeeb degreasing rau degreasing, tau dawb paug.
4. Sintering
Ceramic blanks tau sintered ntawm qhov kub ntawm 1300 ° C ~ 1800 ° C. Sintering yog txheej txheem ntawm kev tsim cov pob zeb ceramic. Ib feem loj ntawm kev ua tau zoo ntawm cov khoom siv ceramic yog txiav txim siab los ntawm sintering. Zirconia ceramics xav tau siab ceev thiab niaj hnub sintering, tsis tsuas yog cov txheej txheem degreasing tseem ceeb heev, tab sis kuj cuam tshuam los ntawm hmoov, additives, sintering kub thiab sij hawm, siab thiab sintering cua thiab lwm yam.
Qhov zoo ntawm ceramic txhaj molding
Lub ntsej muag zoo nkauj ntawm cov khoom siv xws li ceramic watch case, ceramic bezel, ceramic dial, ceramic hauv qab cover, ceramic crown, ceramic watch saw thiab lwm yam khoom, me me, siab precision yuav tsum.
Qhov zoo ntawm kev siv cov yas txhaj tshuaj molding rau cov ntse hnavceramic seem seemyog:
Tuaj yeem ze rau cov net molding geometry complex, muaj zog ua tau zoo, yog li cov khoom lag luam zoo, yog li txo cov nqi ceramic kim heev;
Cov txheej txheem molding muaj qib siab ntawm kev siv tshuab thiab automation, lub voj voog molding yog luv, kev tswj thiab tswj cov txheej txheem ntau lawm kuj yooj yim heev, yooj yim rau kev tsim khoom loj, ntau lawm;
Cov khoom siv molded ceramic muaj qhov tseeb qhov tseeb thiab qhov chaw tiav, qhov ua tiav tuaj yeem ncav cuag 5um. Yog li ntawd,CIM ceramic txhaj tshuaj molding tshuabtau dhau los ua ib txoj hauv kev tsim cov txheej txheem ceramic uas twb muaj lawm.
