Dab tsi yog qhov txawv ntawm molding thiab extrusion?

Wb tshawb nrhiav tshuab molding. Pwm nias, raws li lub npe qhia, yog ib txoj hauv kev ua cov ntaub ntawv siv pwm. Cov txheej txheem no zoo ib yam li tus neeg ua mov ci muab lub khob noom cookie rau hauv pwm los ua ntau yam duab ntawm pastries. Thaum lub sij hawm molding txheej txheem, cov ntaub ntawv raw feem ntau yog thermosetting yas los yog roj hmab. Nyob rau hauv qhov kev txiav txim ntawm cua sov thiab siab, cov khoom yuav ntws mus rau hauv cov kab noj hniav ntawm pwm thiab solidify rau hauv cov duab. Piv txwv li, yas casings ntawm cov khoom siv hauv tsev thiab cov tsheb sab hauv feem ntau yog tsim los ntawm kev siv tshuab molding.
Nyob rau hauv sib piv, cov txheej txheem extrusion yog ntau zoo li ib tug kws ua zaub mov siv ib lub hnab extrusion los extrude zoo nkauj paj duab. Squeezing yog txheej txheem ntawm extruding ib cov khoom mus rau hauv ib tug nruam ntev cov khoom los ntawm ib tug pwm qhov nrog ib tug tshwj xeeb cross-sectional duab. Nws yog tsim nyog rau cov thermoplastic plastics thiab hlau, xws li txhuas profiles, yas kav, thiab lwm yam. Thaum lub sij hawm extrusion txheej txheem, cov khoom yog preheated rau ib tug tej yam kub thiab ces thawb los ntawm pwm qhov los ntawm ib tug ntsia hlau los yog plunger los tsim tus ntoo khaub lig xav tau. -sectional puab, uas yog ces txias thiab zoo li tus.
Los ntawm kev pom cov cuab yeej, lub tshuab molding feem ntau muaj ob ntu, cov pwm sab saud thiab qis, uas tuaj yeem raug kaw kom siv lub siab. Lub extruder, ntawm qhov tod tes, feem ntau yog muaj lub thoob, ntsia hlau, thiab pwm, nrog rau cov khoom txav mus rau pwm nyob rau hauv lub laub ntawm cov ntsia hlau.
Nyob rau hauv cov nqe lus ntawm ntau lawm efficiency, extrusion technology yog feem ntau haum rau loj-scale ntau lawm vim hais tias nws muaj peev xwm tsis tu ncua tsim cov khoom ntawm ntev ntev, zoo li ib tug tas mus li kwj ntawm cov khoom tsim nyob rau hauv ib tug sib dhos kab. Txawm li cas los xij, molding yog qhov tsim nyog rau ntau lawm, vim tias nws tsuas tuaj yeem tsim cov khoom ruaj khov txhua lub sijhawm, ib yam li cov khoom siv tes ua uas tshwj xeeb thiab siv sijhawm ntev.
Los ntawm kev xav ntawm cov yam ntxwv ntawm cov khoom, cov khoom molded muaj qhov zoo ntawm qhov ruaj khov thiab muaj zog txhua yam, raws li cov khoom ua tiav hauv cov pwm, tsim cov qauv ntom ntom. Squeezed cov khoom muaj lub zog siab nyob rau hauv qhov kev taw qhia longitudinal, tab sis tej zaum yuav muaj qee qhov sib txawv vim qhov txias txias.
Tsis tas li ntawd, muaj qhov sib txawv ntawm kev siv cov khoom ntawm molding thiab extrusion. Moulding feem ntau tsim cov khoom pov tseg ntau, vim tias cov khoom siv ntau dhau raug txiav tawm thaum lub sijhawm pwm kaw. Squeezing tuaj yeem siv tau cov ntaub ntawv zoo dua vim tias nws yog cov txheej txheem ntau lawm nrog cov khoom siv tsawg dua.
Thaum kawg, cia peb piv cov txheej txheem no los ntawm kev ua piv txwv. Piv txwv tias peb yuav tsum tsim lub rooj zaum yas. Yog tias siv cov txheej txheem molding, peb tuaj yeem muab tus nqi tsim nyog ntawm cov thermosetting yas rau hauv cov pwm rhuab, siv lub zog siab los sau cov pwm thiab kho nws, thiab thaum kawg tau txais lub rooj zaum yas tiav. Yog tias peb siv tshuab extrusion, peb yuav tsum txuas ntxiv extrude ntau yam ntawm lub rooj zaum, xws li backrest, lub rooj zaum, thiab ob txhais ceg, los ntawm extruder, thiab tom qab ntawd sib sau cov khoom no.
Txawm hais tias ob qho tib si molding thiab extrusion yog cov txheej txheem tseem ceeb rau kev tsim cov yas los yog hlau, lawv muaj lawv tus kheej qhov zoo ntawm cov qauv kev khiav hauj lwm, cov cuab yeej xav tau, kev tsim khoom, cov yam ntxwv ntawm cov khoom, thiab kev siv cov khoom siv. Xaiv cov txheej txheem tsim nyog tsis yog tsuas yog nyob ntawm tus qauv tsim thiab cov khoom siv ntawm cov khoom, tab sis kuj yuav tsum xav txog kev siv nyiaj txiag thiab kev tsim khoom. Yog li ntawd, kev nkag siab txog tus yam ntxwv thiab qhov sib txawv ntawm ob lub thev naus laus zis no yog qhov tseem ceeb rau kev tsim cov engineers thiab cov tsim qauv, vim nws txiav txim siab seb cov khoom puas tuaj yeem ua tiav qhov kev xav tau zoo thiab kev ua tau zoo, ua tau zoo, thiab kev lag luam.
