Dab tsi yog Meant Los ntawm Peev Casting?

Kev nqis peev casting, tseem hu ua ploj-wax casting lossis precision casting, yog cov txheej txheem tsim khoom uas koom nrog kev tsim cov hlau los ntawm kev ua cov hlau molten rau hauv cov pwm precision. Nyob rau hauv txoj kev casting no, lub plhaub ceramic yog tsim nyob ib ncig ntawm cov qauv siv ntawm cov hlau uas xav tau, uas yog tom qab ntawd ua kom sov kom tshem tawm cov qauv siv quav ciab thiab tawm hauv qab lub plhaub ceramic. Tom qab ntawd lub plhaub ceramic yog ntim nrog cov hlau molten, feem ntau ntawm qhov kub thiab txias siab tshaj qhov melting point ntawm cov hlau. Cov hlau molten txias thiab solidifies, noj cov duab ntawm lub plhaub ceramic, thiab lub plhaub ceramic tom qab raug tshem tawm kom pom cov hlau cam khwb cia.

Kev nqis peev casting yog qhov tshwj xeeb zoo rau kev tsim cov duab nyuaj thiab cov duab geometry uas yuav nyuaj rau fabricate siv cov txheej txheem hlau ua haujlwm ib txwm muaj. Cov txheej txheem tuaj yeem rov ua cov ntsiab lus sib txawv heev thiab cov duab geometry, uas yuav tsis yooj yim lossis tsis yooj yim sua kom ua tiav siv cov txheej txheem tsim khoom. Tsis tas li ntawd, peev casting tso cai rau kev tsim cov khoom hlau nrog zoo ib yam, siab qhov tseeb, thiab du nto tiav.

Cov txheej txheem ploj-wax casting pib nrog kev tsim cov qauv, feem ntau yog ua los ntawm cov quav ciab, yas, lossis lwm yam khoom yooj yim yaj. Cov qauv no yog tsim los rov ua dua qhov xav tau geometry thiab nto tiav ntawm cov hlau. Tom qab ntawd tus qauv yog encased nyob rau hauv lub ceramic plhaub, feem ntau yog ua los ntawm ib tug sib tov ntawm refractory ntaub ntawv xws li silica, alumina, thiab zirconia. Lub plhaub ceramic yog tsim nyob ib ncig ntawm tus qauv siv kev txhaj tshuaj molding los yog cov txheej txheem siab-pouring los xyuas kom meej qhov tseeb ntawm cov qauv.

Tom qab lub plhaub ceramic tau tsim nyob ib ncig ntawm cov qauv, nws yog rhuab mus rau qhov kub txaus kom yaj cov qauv khoom. Cov khoom qauv yog tom qab ntawd tshem tawm ntawm lub plhaub ceramic, tawm hauv qab lub qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Molten hlau yog ces nchuav rau hauv pwm kab noj hniav thiab tso cai rau txias thiab solidify. Thaum cov hlau tau solidified, lub plhaub ceramic raug tshem tawm, tawm hauv qab ntawm cov hlau cam khwb cia.

Kev nqis peev casting muaj ntau qhov zoo dua li cov txheej txheem hlau ua haujlwm ib txwm muaj. Nws tso cai rau kev tsim cov duab nyuaj thiab geometry uas yuav tsis yooj yim lossis tsis yooj yim sua kom ua tiav siv cov txheej txheem ib txwm muaj. Tsis tas li ntawd, kev siv cov pwm precision ua kom zoo ib yam thiab ua haujlwm zoo rau txhua qhov cam khwb cia hlau. Cov txheej txheem kuj tseem yuav tsum tau ua haujlwm qis dua piv rau cov txheej txheem kev ua haujlwm hlau ib txwm muaj vim qhov kev ua haujlwm siab ntawm cov txheej txheem casting.

Kev nqis peev casting yog txheej txheem tsim khoom siv cov plhaub ceramic los tsim cov pwm precision rau casting hlau qhov chaw. Nws yog qhov tshwj xeeb zoo rau kev tsim cov duab thiab cov duab geometry uas yuav nyuaj rau fabricate siv cov txheej txheem hlau ua haujlwm ib txwm muaj. Cov txheej txheem tso cai rau high-precision replication ntawm geometry thiab nto tiav thaum tuav tswj zoo ib yam thiab kev ua tau zoo yam ntxwv rau txhua cam khwb cia hlau ib feem.
