Lub molding kub yog cov pwm kub yuav tsum tau thaum lub sij hawm molding, yog li cov kev lag luam tsis txiav txim siab lub tshav kub hloov ntawm cov khoom nyob rau hauv lub pwm kab noj hniav, uas muaj ib tug sib xws txiav txim siab rau lub melting, ntws thiab solidification ntawm cov khoom.
Moulding siab nyob rau hauv lub luag hauj lwm ntawm molding, lub sealing ntawm cov pwm ua rau cov khoom denser, thiab muaj peev xwm txhawb cov ndlwg ntawm molten cov ntaub ntawv thiab sib npaug cov evaporation ntawm tsawg molecular tshuaj nyob rau hauv lub membrane kab noj hniav, uas yuav ua tau ib tug tej yam siab.
Tom qab cov pwm raug kaw los yog zaj duab xis kaw los ntawm qhov kawg deflation, lub sij hawm rau cov khoom yuav tsum tau thermally kho nyob rau hauv zaj duab xis ntawm qhov qhib ntawm pwm.
Nyob rau hauv qhov kev txiav txim ntawm molding lub sij hawm tom qab molding, cov duab ntawm cov pwm kab noj hniav yuav tau. Cov ntaub ntawv molded muaj sijhawm txaus kom pom qhov zoo li qub. Curing feem ntau yog hais txog cov txheej txheem ntawm lub sij hawm system qauv ntawm thermosetting yas molding. Los ntawm qhov kev xav ntawm kev cuam tshuam chemistry, cov txheej txheem kho yog qhov tseem ceeb ntawm cov txheej txheem ntawm kev sib txuas molding.
