Vacuum bagging tseem hu ua ntub molding lossis prepreg molding. Cov txheej txheem no tsim nyog rau kev tsim cov khoom sib xyaw ua ke, loj lossis me, uas tsis tuaj yeem ua los ntawm compression molding. Yav dhau los, nws feem ntau yog siv los tsim cov khoom siv dav hlau thiab cov khoom siv kis las, tab sis nws tsis tshua muaj siv hauv nkoj. Txawm li cas los xij, nrog kev txhim kho thev naus laus zis thiab kev hloov tshiab thiab kev nce qib ntawm cov khoom siv thiab cov khoom siv sib xws, daim ntawv thov ntawm lub tshuab nqus tsev molding tshuab tau dhau los ua ntau dua.
Nws yog tam sim no siv dav hauv aerospace, aviation, tsheb ciav hlau, kiv cua, nkoj, khoom siv kis las, khoom siv kev nyab xeeb thiab lwm yam kev lag luam, tshwj xeeb tshaj yog tsim rau cov khoom lag luam sandwich. Cov khoom siv lub tshuab nqus tsev sib sau - cov txheej txheem nqus hnab ntim hauv tsev hauv lub tshuab nqus tsev moulding kev ua haujlwm, cov khoom siv txhawb nqa feem ntau yog dipped hauv resin los ntawm lub tank resin tov nrog curing tus neeg sawv cev, thiab tom qab ntawd cov khoom siv ntau dhau yog khawb tawm los ntawm kev kho qhov sib txawv ntawm ib khub ntawm rollers. ntawm lub tank resin kom ua tiav cov kua nplaum tsim nyog ua ntej pre-impregnation. Cov khoom siv txhawb nqa yog nteg rau ntawm pwm txau nrog txheej txheej gel. Tom qab tus naj npawb tsim ntawm cov khaubncaws sab nraud povtseg yog ncav cuag, nteg tawm cov pwm tso tawm daim ntaub thiab ces nteg lub nqus hnab zaj duab xis. Cov cheeb tsam ib puag ncig yog kaw nrog daim kab xev, thiab lub tshuab nqus tsev yog tshem tawm kom sib npaug ntawm nws.
