1. Roj hmab txhaj tshuaj molding: Roj hmab txhaj tshuaj molding yog ib txoj kev tsim khoom uas cov khoom siv roj hmab tau ncaj qha rau hauv cov qauv ntawm lub thoob rau vulcanization.Qhov zoo ntawm cov roj hmab txhaj tshuaj molding yog: txawm hais tias nws yog kev ua haujlwm tsis tu ncua, lub voj voog molding luv luv, kev ua haujlwm ntau lawm yog siab, cov txheej txheem kev npaj dawb raug tshem tawm, kev siv zog me me, thiab cov khoom lag luam zoo heev.
2. Yas txhaj tshuaj molding: Yas txhaj tshuaj molding yog ib txoj kev ntawm cov khoom yas.Cov yas molten yog txhaj rau hauv pwm ntawm cov khoom yas los ntawm lub siab, thiab cov khoom yas uas xav tau yog tau los ntawm kev txias thiab molding.Muaj cov tshuab txhaj tshuaj molding tshuab tshwj xeeb rau kev txhaj tshuaj molding.Cov yas siv niaj hnub no feem ntau yog polystyrene.
3. Moulding thiab txhaj tshuaj molding: Cov duab uas tau tshwm sim feem ntau yog cov khoom kawg, thiab tsis muaj lwm yam kev ua haujlwm ua ntej kev teeb tsa lossis siv los ua cov khoom kawg.Ntau cov ntsiab lus, xws li cov thawj coj, cov tav, thiab cov xov, tuaj yeem tsim hauv ib qho kev txhaj tshuaj molding.
Txhaj tshuaj molding kuj yog lub tshuab ua khau.Tom qab qhov saum npoo yog khi rau ntawm aluminium kawg, nws feem ntau yog ncaj qha mus rau hauv PVC, TPR thiab lwm yam ntaub ntawv los ntawm lub tshuab turntable los tsim ib leeg ib zaug.Niaj hnub no, tseem muaj PU (tshwj xeeb lub npe polyurethane) txhaj tshuaj molding ( tshuab thiab pwm nrog General txhaj molding yog txawv).
Qhov zoo: Vim nws yog tsim los ntawm lub tshuab, cov zis yog loj, yog li tus nqi qis.
Qhov tsis zoo: Yog tias muaj ntau yam qauv, nws muaj teeb meem ntau dua rau kev hloov pwm, cov khau tsis yooj yim rau cov duab, thiab tsis muaj cov khau txias-nplaum nrog kev ua haujlwm zoo, yog li nws feem ntau tsim nyog rau kev txiav txim nrog ib tus qauv nkaus xwb.
Lub hom phiaj, kev ua haujlwm thiab qhov tshwm sim ntawm qhov kub thiab txias, siab, ceev thiab txias tswj
