Compression Moulding
Compression molding yog txheej txheem ntawm molding nyob rau hauv uas lub preheated polymer yog muab tso rau hauv ib qho qhib, rhuab pwm kab noj hniav. Cov pwm yog tom qab ntawd kaw nrog lub hau ntsaws sab saum toj thiab compressed thiaj li muaj cov khoom sib cuag rau txhua qhov chaw ntawm pwm.
Cov txheej txheem no tuaj yeem tsim cov khoom nrog ntau qhov ntev, thicknesses, thiab complexities. Cov khoom uas nws tsim muaj kuj muaj zog, ua rau nws yog ib tug txaus nyiam txheej txheem rau ib tug xov tooj ntawm txawv industries.
Thermoset composites yog cov khoom siv feem ntau siv hauv compression molding.
Plaub kauj ruam tseem ceeb
Muaj plaub cov kauj ruam tseem ceeb rau cov txheej txheem thermoset composite compression molding:
- Lub zog siab, ob feem ntawm cov khoom siv hlau yog tsim kom haum raws li qhov yuav tsum tau ua los tsim qhov xav tau. Tom qab ntawd lub cuab yeej yog ntsia rau hauv ib lub xovxwm thiab rhuab.
- Cov khoom sib xyaw uas xav tau yog pre-formed rau hauv cov duab ntawm lub cuab yeej. Pre-forming yog ib kauj ruam tseem ceeb uas yuav pab txhim kho qhov ua tiav ntawm qhov tiav.
- Qhov pre-formed ib feem yog muab tso rau hauv lub rhuab pwm. Cov cuab yeej yog compressed nyob rau hauv siab heev, feem ntau yog li ntawm 800psi mus rau 2000psi (nyob ntawm seb lub thickness ntawm ib feem thiab hom ntawm cov khoom siv).
- Ib feem raug tshem tawm ntawm lub cuab yeej tom qab lub siab tso tawm. Txhua lub teeb nyem nyob ib ncig ntawm cov npoo kuj raug tshem tawm lub sijhawm no.
Qhov zoo ntawm Compression Molding
Compression molding yog cov txheej txheem nrov rau ntau yam. Ib feem ntawm nws cov koob meej yog los ntawm kev siv cov khoom sib xyaw ua ke. Cov ntaub ntawv no zoo li muaj zog, tawv, sib zog, thiab tiv taus corrosion ntau dua li cov hlau, ua rau cov khoom zoo dua. Cov neeg tsim khoom siv ua haujlwm nrog cov khoom siv hlau pom tias nws yooj yim heev los hloov cov khoom tsim los rau cov hlau rau hauv qhov compression molding. Vim hais tias nws muaj peev xwm ua tau raws li cov hlau seem geometry nrog cov txheej txheem no, nyob rau hauv ntau qhov xwm txheej ib tus tuaj yeem tso rau hauv thiab hloov cov hlau tag nrho.
