Hauv kev lag luam hauv tsheb kev lag luam, cov txheej txheem hlwv tau dav siv los tsim cov khoom lag luam sab hauv thiab sab nrauv, thiab cov khoom siv hluav taws xob, ua kom muaj txiaj ntsig zoo, thiab kev txhim kho kev txhim kho kom zoo, thiab luv pwm kev txhim kho kev txhim kho. Cov kev ua tau zoo thiab cov tsos ntawm cov seem no nyob ntawm qhov kev xaiv ntawm lawv "raw khoom"- cov yas ntawv yas. Xaiv cov ntawv yog, zoo li kev ua raws li cov kev xav tau ntawm ib qho kev lag luam hauv tsheb, yog qhov tseem ceeb rau kev sib npaug ntawm cov khoom lag luam zoo, ua tau zoo, thiab tus nqi. Cov txheej txheem xaiv yuav tsum muaj kev txiav txim siab ntawm cov ntsiab lus sab hauv qab no.
Txheeb xyuas daim ntawv thov cov xwm txheej thiab cov kev ua tau zoo.
Nov yog thawj kauj ruam thiab tseem ceeb tshaj plaws hauv cov khoom xaiv. Cov chaw sib txawv thiab cov haujlwm ua haujlwm sib txawv uas xav tau ntawm daim ntawv ua haujlwm.
Rau cov seem hauv sab hauv (xws li cov twj paj nruag thiab cov cuab yeej siv hluav taws xob): Kev Nyab Xeeb thiab Kev Nyab Xeeb yog qhov txiav txim siab. Lawv yuav tsum ua kom tiav cov nplaim hluav taws (xws li ul94 v}- 0 ntsuam xyuas qes los tiv thaiv kev noj qab haus huv ntawm cov tsav tsheb thiab cov neeg caij tsheb. Tsis tas li ntawd, cov saum npoo yuav tsum muaj cov qauv zoo dua thiab txau {} Thauj cov kabmob, xws li ntsuas vaj huam sib luag cov thaib, kuj tseem xav tau cov kev sib tw txaus thiab cuam tshuam tsis kam.
Sab nrauv sab nrauv (xws li underbody panels thiab xav tau cov ntaub ntawv sib txawv ntawm cov huab cua zoo (} Tawv thiab laus {- Cov ntaub ntawv tiv taus feem ntau xaiv rau cov feem no.
Cheebtsam muaj cov khoom siv hluav taws xob (xws li cov roj teeb roj teeb thiab cov khoom siv muaj tshwj xeeb rau qhov siab - kub ua hauj lwm, rwb thaiv tsev, thiab seem ruaj khov. Piv txwv li, cov khoom siv nyob ze lub cav hauv lub cav yuav tsum tiv thaiv kub siab ntev txog 100℃rau ncua sijhawm; Roj teeb roj teeb xav tau kev nyab xeeb rwb txog kev nyab xeeb.
Kev soj ntsuam cov yam ntxwv ntawm cov ntaub ntawv ntawm cov ntaub ntawv
Thaum cov kev xav tau kev kawm tau meej, kev sib tw ncaj ncees tuaj yeem ua rau ntawm cov ntaub ntawv hlwv cov ntaub ntawv.
Abs (acrylonitrile - butadiene {{1} Kev ua tau zoo, thiab cov khoom siv yooj yim tshaj plaws rau cov khoom siv hauv tsheb. Txawm li cas los xij, nws cov huab cua tsis kam thiab siab- kub kuj yog tsawg, thiab feem ntau yog siv nyob hauv lub tsheb sab hauv.
PP (polypropylene): Tus nqi qis, qis dua, zoo heev tshuaj lom, thiab rov ua dua tshiab. Iav Fiber ntau lossis cov pob zeb hauv av (pp {{ Nws yog dav siv nyob rau hauv cov khoom loj xws li lub qhov rooj vaj huam thiab pob tw.
PC (Polycarbonate): paub txog nws cov txiaj ntsig zoo heev thiab muaj peev xwm tiv thaiv kub, nws tuaj yeem tiv taus cua sov ntau dua 120 degree. Nws yog feem ntau siv nyob rau hauv kev tsim cov khoom siv uas yuav tsum muaj kev nyab xeeb lossis kev nyab xeeb nrog rau lwm cov ntaub ntawv los ua cov ntawv PC / ABS. Sib txuas cov cua sov thiab cuam tshuam tsis kam ntawm pc nrog lub txheej txheem ntawm ib qho, nws yog qhov kev xaiv zoo tshaj plaws rau high}}}}}}}}}}}}}}}}}}}}}}}} Kawg ntsuas cov thav duab.
PMMA (polymethyl methacrylate, feem ntau yog hu ua acrylic): nws muaj zoo heev tiv thaiv thiab huab cua tsis kam, siab tawv, thiab kos tsis kam. Nws yog feem ntau siv nyob rau hauv cov teeb meem los yog txheej txheej saum npoo ntawm cov vaj huam sib luag ntawm cov panels, muab ib qho tsos ruaj khov thiab zoo nkauj.
Composite (xws li ABS / PVC, PP / PP): FOLMs lossis cov ntawv qhia los ntawm cov khoom sib xyaw ua ke los ntawm kev lamination los ntawm kev lamination los ntawm kev lamination lossis kev ua tiav cov khoom sib txuam. Piv txwv li, ABS / PVC ntawv sib txuas ntawm qhov tsis muaj peev xwm ntawm tus Abs nrog kev hloov pauv thiab muaj feem xyuam rau cov vaj huam sib luag xav tau hemming.
Kev ntsuas cov txheej txheem sib raug zoo thiab raug nqi - ua hauj lwm zoo
Ntxiv rau cov khoom siv tau txais cov khoom, sib thooj nrog cov txheej txheem thermoforming no yuav tsum tau txiav txim siab.
Thermoforming lub qhov rai: Cov khoom yuav tsum muaj ib qho kev tsim nyog thiab ruaj khov kub thiab yooj yim ncab yam tsis muaj kev tawg lossis ntau dhau sagging.
Ncab piv thiab kev sib sib zog nqus kev ua tau zoo: rau cov txheej txheem sib sib zog nqus tau kom ntseeg tau tias muaj kev sib cais ntawm cov txheej txheem moulding thiab zam dhau cov ces kaum ntau dhau.
Tus nqi tswj: thaum ntsib txhua qhov kev ua tau zoo, "kev ua tau zoo" yuav tsum tau ua raws li. Qhov no suav nrog cov ntawv sau nqi, ua kev siv hluav taws xob, seem ntawm cov nqi, thiab cov peev xwm rau kev hloov kho. Pp muaj qhov txiaj ntsig zoo hauv qhov no.
Hauv cov ntsiab lus, xaiv cov ntaub ntawv yas rau cov txheej txheem thermoforming ntawm cov khoom siv tsheb yas yog qhov kev txiav txim siab hauv cov txheej txheem. Nws pib nrog kev nkag siab tob tob ntawm cov muaj nuj nqi, ib puag ncig, ua raws li cov khoom sib txuam ntawm cov khoom siv sib txawv, thiab huab cua kev sib tw ua ke nrog cov txiaj ntsig kev lag luam tag nrho. Tsuas yog los ntawm cov txheej txheem nruj "kev ua kom nruj" tuaj yeem ua rau muaj kev sib haum xeeb, ua rau muaj kev zoo nkauj thiab kev nyab xeeb ntawm cov tsheb niaj hnub no.
