Nyob rau hauv kev lag luam automotive niaj hnub, kev txhaj tshuaj molding qhov yog qhov tseem ceeb ntawm lub teeb thiab cov tub luam khoom. Lawv tus qauv tsim ncaj qha cuam tshuam cov tsheb ua haujlwm, cov nqi tsim khoom, thiab ib puag ncig kev ruaj ntseg. Raws li kev lag luam automotive hloov zuj zus thiab muaj tswv yim tsav tsheb molding qhov chaw tsis muaj kev siv rau kev siv kev ua haujlwm tau yooj yim ntxiv; Nws yuav tsum tau muaj kev sib npaug zoo ntawm kev txhim kho cov txheej txheem, cov ntaub ntawv txuj ci, kev tsim khoom, thiab tswj kav. Kab lus no yuav tshawb nrhiav cov qauv tseem ceeb cov ntsiab lus rau kev siv tsheb tshuab ob lub siab: kev xaiv, thiab cov khoom siv.
1. Ua haujlwm ua ntej: precision tsim kom tau raws li kev ua haujlwm nyuaj
Kev txhaj tshuaj molding qhov yog siv nyob rau hauv ntau yam kev siv tsheb, xws li cov twj paj nruag (xws li cov cuab yeej siv hluav taws xob), sab nrauv (xws li powerforing), thiab powertrain (xws li sensor nkhaus). Lawv cov qauv tsim nyog yuav tsum tau ua raws li cov cai tswj tau nruj. Piv txwv li, kev txhaj tshuaj sab nrauv tuaj yeem tsim cov kev cuam tshuam, thiab qis shrinkage los xyuas kom meej qhov ntev ntev li ntev}. Sab hauv, ntawm qhov tod tes, yuav tsum saib xyuas cov khoom lag luam zoo li no, thiab cov khoom siv voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (voc (volatile organic compound, thiab ua raws li cov kev cai ib puag ncig.
Daim ntawv thov ntawm Cee (Computer {{{-}}} kev siv tshuab ua haujlwm) kev simulation yog qhov tseem ceeb thaum cov txheej txheem tsim. Mouldflow tsom xam cov neeg tsim tawm kom kwv yees cov kab ke yaj, thiab cov txheej ntsa ua kom tsis txhob muaj qhov tsis xws luag xws li lub dab dej thiab cov hnab ris huab cua. Tsis tas li ntawd, kev tsim qauv muaj nuj nqis yuav tsum xav txog qhov kev ua siab loj ntawm lub rooj sib txoos
Ii. Ntau lawm tau ua haujlwm: Modularity thiab tsim rau kev ua neeg tsim khoom lag luam (DFM)
Kev lag luam automotive kev lag luam qhov chaw xav tau siab heev ntawm tus nqi tswj hwm thiab kev tsim tau. Yog li ntawd, kev tsim cov kev txhaj tshuaj molding qhov yuav tsum ua raws li kev tsim qauv rau kev ua neeg tsim khoom lag luam (DFM). Modular tsim yog lub tswv yim tseem ceeb. Los ntawm kev sib xyaw ua ke ntau lub zog ua rau ib feem ntawm cov txheej txheem dashboard, cov khoom sib xyaw ua ke, thiab cov txheej txheem sib dhos ua ke tuaj yeem tuaj yeem ua kom tawg tau, thiab cov khoom siv khoom siv txuas ntxiv tuaj yeem txo. Piv txwv li, tus qauv tesla qauv 3 tus sab hauv siv ntau ntawm cov khoom siv cov khoom siv hauv ntau pua pua ntawm cov khoom me me.
Tsis tas li ntawd, qhov kev sib tw ntawm kev tsim pwm txuas ncaj qha cuam tshuam kev ua tau zoo. Cov neeg tsim qauv yuav tsum soj ntsuam cov kab parting thaj chaw, thiab Ejector cov qauv ua ntej yuav ua rau txuas ntxiv lub caij nyoog lossis cov khoom lag luam tsis xws luag. Tsis tas li ntawd, kev siv ntau {{2} kab noj hniav pwm (xws li qhov no yuav tsum tau nce ib leeg ntau lawm, tab sis yuav tsum tau nce ib leeg ntau lawm, Rau cov qauv ntim ntau (xws li kev lag luam sedans nrog rau cov muaj peev xwm txhua xyoo (xws li txuas ntxiv txo cov nqi txhim kho pwm thiab cov khoom kom nrawm dua cov khoom lag luam thiab cov khoom nrawm.
III. Txhawb cov ntaub ntawv txuj ci keeb kwm: kos duab ntawm kev ntsuas kev sib tw thiab kev ua haujlwm
Xaiv cov khoom siv rau kev txhaj tshuaj hauv kev txhaj tshuaj molding qhov yuav tsum tau nrhiav qhov kev pom kev zoo siab, lub zog, thiab tus nqi. Tsoos Termoplastics (xws li PP, Abs, thiab PC / Abs alloys) nyob twj ywm los ntawm kev hloov kho cov iav (xws li iav fiber ntau). Piv txwv li, PP txhawb nrog 30% fiber ntau tuaj yeem nce rigidity los ntawm ntau tshaj 50%, ua rau nws haum rau lub tshuab ntsuas. Nylon (pa) alloys nrog qis linear nthuav coefficients feem ntau yog siv hauv hluav taws xob txuas yuav tsum tau muaj siab- kub tsis kam.
Nyob rau hauv xyoo tsis ntev los no, kev siv Bio -} Raws plastics thiab cov khoom siv ua tau rov ua dua tshiab tau dhau los ua cov ncauj lus kub hauv kev lag luam. Piv txwv li, xyaw polylactic acid (PLA) thiab rov ua dua tsiaj (rpet) tuaj yeem tswj tau kev ua tau zoo thaum txo cov hneev taw. Cov automakers xws li BMW thiab Audi tau pib siv cov ntaub ntawv no (xws li cov khoom siv 2030 Tsis tas li ntawd, nanocomposites (xws li montmorillonite {}}} estistatic cov expertancation, nthuav tawm daim ntawv thov kev txhaj tshuaj ntawm kev txhaj tshuaj molding.
IV. Kev ruaj khov txhim kho: ib puag ncig lub luag haujlwm thoob plaws hauv lub neej
Tsav los ntawm "ob lub hom phiaj" cov hom phiaj thiab cov qauv tsim ntawm cov kab ke hauv lub cev yuav tsum tau siv cov philosople}}} kev tswj hwm hluav taws xob thoob plaws hauv txhua lub neej tag nrho. Ua ntej, tus nqi sib cav tsim (xws li nyias- phab ntsa txhaj tshuaj molding) muaj peev xwm cuam tshuam ncaj qha rau kev noj khoom. Kev lag luam tam sim no - ua nyias-}}}}}}}}} {8} Pab txhaj tshuaj molding (Gaim). Thib ob, tshem tawm thiab rov ua cov qauv txheej txheem (xws li kev zam kev sib txuas ntawm hlau thiab yas) tuaj yeem txhim kho kev ua haujlwm ntawm kev sib cais los ntawm cov tsheb sib cais.
Kaw - rop ntau lawm tshuab Piv txwv li, qee cov neeg ua lag luam tau tsim muaj "siv cov khoom siv txuas ntxiv → Cov tsheb sib txuas tshiab hauv cov tsheb sab hauv xws li cov tub ceev xwm theem nrab. Tsis tas li ntawd, cov cuab yeej digital (xws li blockcee lub tshuab
Cov qauv tsim kho lub tswv yim rau kev txhaj tshuaj molding hauv kev lag luam hauv tsheb tau hloov kho rau cov kev ua haujlwm engineering rau multi- hom phiaj kev ua kom zoo dua. Nyob rau hauv lub neej yav tom ntej, nrog kev hloov pauv tshiab hauv i {}} Kev txhaj tshuaj pwm, thiab cov ntaub ntawv ntsuab, cov khoom siv ntse, {{}} carbon transformation. Cov neeg tsim qauv yuav tsum muaj kev sib xyaw ua ke engineering, cov ntaub ntawv, thiab ib puag ncig cov neeg xav tau thaum tsav tsheb kev lag luam kev ua haujlwm ntawm kev ua haujlwm zoo thiab muaj kev ua haujlwm.
