Cov txheej txheem molding yog ib qho nyiaj ntawm prepreg rau hauv cov hlau pwm kab noj hniav ntawm cov pwm, kev siv cov presses nrog lub tshav kub qhov chaw los tsim ib tug tej yam kub thiab siab kom lub prepreg nyob rau hauv pwm kab noj hniav yog softened los ntawm tshav kub, siab txaus, tag nrho ntawm txaus, puv nrog cov kab noj hniav molding thiab curing khoom ntawm ib tug txheej txheem txheej txheem.
Covtxheej txheem moldingyog tus cwj pwm los ntawm kev xav tau cua sov hauv cov txheej txheem molding, lub hom phiaj ntawm cov cua sov yog ua kom cov prepreg resin softening txaus, tag nrho ntawm pwm kab noj hniav, thiab ceev cov tshuaj tiv thaiv ntawm cov khoom siv matrix resin. Thaum lub sij hawm tus txheej txheem ntawm kev sau cov pwm kab noj hniav nrog prepreg, tsis yog tsuas yog cov resin matrix ntws, tab sis kuj cov ntaub ntawv reinforcing, thiab covresinmatrix thiab reinforcing fibers sau tag nrho cov seem ntawm pwm kab noj hniav ib txhij.
Tsuas yog cov resin matrix viscosity loj heev, thiab daim ntawv cog lus muaj zog txaus kom ntws nrog cov fibers reinforcing, yog li cov txheej txheem molding yuav tsum muaj ntau dua molding. Qhov no yuav tsum tau hlau pwm nrog lub zog siab, siab precision, thiab corrosion kuj, thiab nws yuav tsum tau siv tshwj xeeb kub presses los tswj qhov kub ntawm curing molding, siab, tuav lub sij hawm, thiab lwm yam txheej txheem tsis.
Cov txheej txheem molding ntawm kev ua haujlwm siab, cov khoom loj raug, thiab qhov chaw tiav, tshwj xeeb tshaj yog rau cov qauv ntawm cov khoom sib xyaw ua ke feem ntau tuaj yeem ua pwm ib zaug, thiab yuav tsis ua rau kev ua haujlwm ntawm cov khoom siv sib xyaw. Nws lub ntsiab tsis txaus yog qhov pwm tsim thiab kev tsim khoom yog qhov nyuaj dua, thiab kev nqis peev thawj zaug loj dua. Txawm hais tias cov txheej txheem molding muaj qhov tsis zoo saum toj no, cov pwmtxheej txheem moldingtseem occupies ib qho tseem ceeb txoj hauj lwm nyob rau hauv cov khoom sib xyaw molding txheej txheem.
1. Kev npaj
Ua ib txoj hauj lwm zoo ntawm prepreg, molding tooling pwm, nrog rau qhov cub ntsuas qhov kev txhawb nqa ua haujlwm, thiab ntxuav cov pwm hauv qhov kawg ntawm kev siv cov residual resin, thiab cov khib nyiab, kom cov pwm huv si thiab du.
2. Txiav thiab tso prepregs
Yuav ua rau cov khoom ntawm carbon fiber raw cov ntaub ntawv npaj txhij, prepreg tom qab dhau qhov kev tshuaj xyuas, xam thaj tsam ntawm raw cov ntaub ntawv, cov ntaub ntawv, cov ntaub ntawv, cov ntaub ntawv raw txheej los ntawm txheej ntawm xyab ntxiv, nyob rau tib lub sij hawm nyob rau hauv lub superposition ntawm cov khoom rau lub pre-siab, nias rau hauv cov duab ntawm ib tug tsis tu ncua, qhov zoo ntawm ib tug tej yam xov tooj ntawm cov khoom ntom ntom.
3. Pwm thiab kho
Muab cov ntaub ntawv raw khoom tso rau hauv pwm, thiab tib lub sijhawm nyob rau hauv cov hnab yas sab hauv, kaw cov pwm, tag nrho rau hauv lub tshuab molding, cov hnab yas sab hauv ntxiv rau ib qho kev siab tsis tu ncua, qhov kub thiab txias, teem lub sij hawm tas li kom nws kho.
4. Txias thiab demolding
Tom qab ib lub sij hawm ntawm lub siab sab nraum pwm thawj txias paub rau ib lub sij hawm ntawm lub sij hawm, thiab ces qhib lub pwm, demolding sab nraum lub qhov muag los ntxuav lub tooling pwm.
5. Cov txheej txheem molding
Tom qab demolding cov khoom yuav tsum tau muab ntxuav, nrog ib tug txhuam steel los yog tooj liab txhuam kom tshem tawm cov residual yas, thiab tshuab nrog compressed cua, cov khoom molded yog polished, thiaj li hais tias tus nto yog du thiab huv si.
6. Kev kuaj tsis raug thiab kev soj ntsuam zaum kawg
Kev kuaj tsis muaj kev puas tsuaj thiab kev tshuaj xyuas zaum kawg ntawm cov khoom yog ua raws li cov kev xav tau ntawm cov ntaub ntawv tsim.
Txij thaum yug loscarbon fiber ntau, ib txwm txwv los ntawm cov nqi tsim khoom thiab kev sib tw ntau lawm, tsis tau siv rau ntau qhov ntau. Qhov kev txiav txim siab ntawm carbon fiber ntau cov nqi thiab yeej yog cov txheej txheem molding, carbon fiber ntau cov khoom siv molding txheej txheem muaj ntau, xws li RTM, VARI, kub xovxwm tank, cub curing prepreg (OOA), thiab lwm yam., tab sis muaj ob lub bottlenecks: 1, lub sij hawm molding lub sij hawm ntev; 2, tus nqi yog kim (piv rau hlau thiab yas). Prepreg molding txheej txheem, raws li ib yam ntawm cov txheej txheem molding, muaj peev xwm paub batch ntau lawm thiab txo nqi ntau lawm, uas yog ntau thiab ntau lug siv.
