Cov teeb meem uas yuav tshwm sim hauv SMC molding txheej txheem yog: blistering thiab sab hauv bulging ntawm qhov chaw ntawm cov khoom; warpage thiab deformation ntawm cov khoom; tawg hauv cov khoom tom qab ib lub sijhawm, thiab ib feem ntawm cov fiber raug ntawm cov khoom. Cov laj thawj rau cov xwm txheej cuam tshuam thiab cov kev ntsuas pov tseg yog raws li nram no:
1. Ua npuas ncauj rau ntawm qhov chaw lossis bulging sab hauv cov khoom
Qhov ua rau muaj qhov teeb meem no tej zaum yuav yog vim cov dej noo thiab cov khoom tsis ruaj khov hauv cov khoom siv siab dhau; qhov kub ntawm pwm siab dhau lossis qis dhau; qhov siab tsis txaus thiab lub sijhawm tuav luv dhau; qhov cua sov ntawm cov khoom siv tsis sib npaug. Kev daws teeb meem yog tswj hwm cov khoom tsis ruaj khov hauv cov khoom siv, kho qhov kub ntawm pwm kom raug, thiab tswj hwm qhov siab ntawm pwm thiab lub sijhawm tuav kom raug. Txhim kho lub cuab yeej cua sov kom cov khoom siv tau cua sov sib npaug.
2. Khoom deformation thiab warpage
Qhov xwm txheej no yuav tshwm sim los ntawm kev kho tsis tiav ntawm FRP / SMC, qhov kub molding qis thiab lub sijhawm tuav tsis txaus; cov khoom tuab tsis sib xws, ua rau tsis sib xws shrinkage.
Qhov kev daws teeb meem yog kom tswj hwm qhov kub thiab txias thiab lub sijhawm tuav; xaiv cov khoom siv pwm nrog tus nqi me me; nyob rau hauv lub hauv paus ntawm kev ua tau raws li qhov yuav tsum tau ua ntawm cov khoom, cov qauv ntawm cov khoom raug hloov pauv kom raug kom ua rau qhov tuab ntawm cov khoom sib xws li sai tau lossis hloov pauv du.
3. Cov kab nrib pleb
Qhov xwm txheej no feem ntau tshwm sim hauv cov khoom uas muaj cov ntxig. Qhov laj thawj yuav yog. Cov qauv ntawm cov ntxig hauv cov khoom tsis tsim nyog; tus naj npawb ntawm cov ntxig ntau dhau; txoj kev demoulding tsis tsim nyog, thiab qhov tuab ntawm txhua qhov ntawm cov khoom txawv dhau. Kev daws teeb meem yog hloov cov qauv ntawm cov khoom raws li cov xwm txheej tso cai, thiab cov ntxig yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm molding; tsim cov txheej txheem demoulding kom zoo kom ntseeg tau tias lub zog ejection nruab nrab.
4. Cov khoom nyob rau hauv kev nyuaj siab, hauv zos tsis muaj kua nplaum
Qhov laj thawj rau qhov xwm txheej no yuav yog qhov tsis txaus siab; ntau dhau ntawm cov khoom siv thiab tsis txaus pub mis; kub dhau, yog li ntawd ib feem ntawm cov khoom siv pwm khov ua ntej lub sijhawm.
Qhov kev daws teeb meem yog tswj hwm qhov kub thiab txias ntawm cov pwm, qhov siab thiab lub sijhawm nias; xyuas kom meej tias muaj cov ntaub ntawv txaus thiab tsis muaj cov ntaub ntawv tsis txaus.
5. Cov khoom nplaum pwm
Qee zaum cov khoom lo rau ntawm pwm thiab tsis yooj yim tso tawm, uas ua rau puas tsuaj rau cov tsos ntawm cov khoom. Qhov laj thawj yuav yog vim cov tshuaj tso tawm sab hauv ploj lawm hauv cov khoom siv; cov pwm tsis tau ntxuav thiab cov tshuaj tso tawm tsis nco qab; qhov chaw ntawm cov pwm puas lawm. Kev daws teeb meem yog los tswj hwm qhov zoo ntawm cov khoom siv, ua tib zoo ua haujlwm, thiab kho cov pwm puas tsuaj raws sijhawm kom ua tiav cov pwm tiav.
6. Cov ntug pov tseg ntawm cov khoom yog tuab dhau lawm
Qhov laj thawj rau qhov xwm txheej no tej zaum yuav yog kev tsim pwm tsis tsim nyog; ntxiv cov khoom siv ntau dhau, thiab lwm yam. Kev daws teeb meem yog ua kom muaj kev tsim pwm tsim nyog; tswj hwm qhov ntau ntawm kev pub mis.
7. Qhov loj ntawm cov khoom tsis tsim nyog
Qhov laj thawj rau qhov xwm txheej no tej zaum yuav yog qhov zoo ntawm cov khoom siv tsis ua tau raws li qhov yuav tsum tau ua; kev pub mis tsis nruj; pwm hnav; qhov loj me ntawm tus qauv pwm tsis raug, thiab lwm yam. Kev daws teeb meem yog tswj hwm qhov zoo ntawm cov khoom siv thiab pub cov khoom siv kom raug. Qhov loj me ntawm tus qauv pwm yuav tsum raug. Cov pwm puas tsuaj yuav tsum tsis txhob siv.
Cov teeb meem ntawm cov khoom thaum lub sijhawm molding tsis txwv rau cov saum toj no. Hauv cov txheej txheem ntau lawm, sau cov kev paub dhau los, kev txhim kho tas mus li, thiab txhim kho qhov zoo.
