Cov teeb meem uas yuav tshwm sim hauv SMC molding txheej txheem yog: blistering thiab bulging sab hauv ntawm cov khoom;warpage thiab deformation ntawm cov khoom;tawg nyob rau hauv cov khoom tom qab ib lub sij hawm ntawm lub sij hawm, thiab ib feem ntawm fiber raug ntawm cov khoom.Cov laj thawj rau cov xwm txheej cuam tshuam thiab kev ntsuas pov tseg yog raws li hauv qab no:
1. Foaming ntawm qhov chaw los yog bulging hauv cov khoom
Qhov ua rau ntawm qhov tshwm sim no tuaj yeem yog cov ntsiab lus ntawm cov dej noo thiab cov teeb meem tsis zoo hauv cov khoom siv ntau dhau;pwm kub yog siab dhau los yog tsawg dhau;lub siab tsis txaus thiab lub sijhawm tuav yog luv dhau;cov cua sov ntawm cov khoom siv tsis sib xws.Txoj kev daws teeb meem yog tswj xyuas cov ntsiab lus tsis hloov pauv hauv cov khoom, tsim nyog kho cov pwm kub, thiab tsim nyog tswj lub molding siab thiab tuav lub sij hawm.Txhim kho cov cuab yeej cua sov kom cov khoom cua sov sib npaug.
2. Khoom deformation thiab warpage
Qhov tshwm sim no tuaj yeem tshwm sim los ntawm kev kho tsis tiav ntawm FRP / SMC, qhov kub thiab txias tsis txaus thiab lub sijhawm tuav tsis txaus;uneven thickness ntawm cov khoom, uas ua rau tsis sib xws shrinkage.
Txoj kev daws teeb meem yog tswj xyuas qhov kub thiab txias thiab tuav lub sijhawm;xaiv cov khoom molded nrog me me shrinkage tus nqi;raws li qhov ua tau raws li qhov yuav tsum tau ua ntawm cov khoom, cov qauv ntawm cov khoom raug hloov kom tsim nyog los ua kom cov thickness ntawm cov khoom sib xws li qhov ua tau lossis kev hloov pauv.
3. Kev tawg
Qhov no tshwm sim feem ntau tshwm sim nyob rau hauv cov khoom nrog inserts.Qhov laj thawj yuav yog.Cov qauv ntawm cov ntxig rau hauv cov khoom yog tsis tsim nyog;tus naj npawb ntawm inserts yog ntau dhau;txoj kev demoulding yog tsis tsim nyog, thiab lub thickness ntawm txhua feem ntawm cov khoom yog txawv heev.Kev daws yog hloov cov qauv ntawm cov khoom raws li kev tso cai, thiab cov ntxig yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm molding;tsim nyog tsim lub demoulding mechanism los xyuas kom meej qhov nruab nrab ejection quab yuam.
4. Cov khoom yog nyob rau hauv siab, lub zos tsis muaj kua nplaum
Yog vim li cas rau qhov tshwm sim no tej zaum yuav tsis txaus siab;ntau fluidity ntawm cov khoom thiab tsis txaus noj npaum li cas;kub siab heev, yog li ntawd ib feem ntawm cov khoom molded solidifies ntxov ntxov.
Cov tshuaj yog nruj me ntsis tswj qhov molding kub, siab thiab nias lub sij hawm;xyuas kom cov ntaub ntawv txaus thiab tsis muaj cov khoom tsis txaus.
5. Khoom nplaum pwm
Qee lub sij hawm cov khoom lo rau cov pwm thiab tsis yooj yim rau kev tso tawm, uas ua rau muaj kev puas tsuaj loj ntawm cov khoom.Qhov laj thawj yog vim li cas tus neeg tso tawm sab hauv yog ploj lawm hauv cov khoom;cov pwm tsis raug ntxuav thiab tso tawm tus neeg sawv cev tsis nco qab;qhov saum npoo ntawm cov pwm puas lawm.Txoj kev daws teeb meem yog tswj hwm cov khoom zoo, ua tib zoo ua haujlwm, thiab kho pwm puas hauv lub sijhawm kom ua tiav cov pwm tiav.
6. Cov ntug khib nyiab ntawm cov khoom yog tuab heev
Yog vim li cas rau qhov tshwm sim no tej zaum yuav tsis tsim pwm tsim;Cov khoom siv ntau dhau lawm, thiab lwm yam. Qhov kev daws teeb meem yog ua kom tsim pwm tsim nyog;nruj me ntsis tswj tus nqi pub mis.
7. Cov khoom loj yog tsis tsim nyog
Yog vim li cas rau qhov tshwm sim no yuav yog qhov zoo ntawm cov khoom tsis ua raws li qhov yuav tsum tau ua;kev pub mis tsis nruj;cov pwm yog hnav;pwm tsim qhov loj me tsis raug, thiab lwm yam kev daws teeb meem yog tswj xyuas cov ntaub ntawv zoo thiab raug pub rau cov ntaub ntawv.Qhov loj ntawm cov pwm tsim yuav tsum yog qhov tseeb.Cov pwm puas yuav tsum tsis txhob siv.
Cov teeb meem ntawm cov khoom thaum lub sij hawm molding txheej txheem tsis txwv rau saum toj no.Hauv cov txheej txheem tsim khoom, suav nrog kev paub dhau los, kev txhim kho txuas ntxiv, thiab txhim kho kom zoo.
