Precision txhaj molding ua yog txheej txheem nruj heev, kev txhaj tshuaj molding ua tiav ntawm qhov kev xav tau ntawm qhov loj yog nruj heev, yog li peb yuav tsum paub qee cov txheej txheem yuav tsum tau ua thaum precision txhaj tshuaj molding ua, txhawm rau kom ua tiav qhov kev txhaj tshuaj pwm ua tiav, cov hauv qab no tshwj xeeb Ming precision editor los qhia rau koj qee qhov kev txhaj tshuaj molding kev txiav txim siab.
A, precision txhaj molding shrinkage:
yas ntau yam ntawm thermoplastic molding txheej txheem vim hais tias tseem muaj crystallization ntawm cov duab ntawm lub ntim hloov, muaj zog nyob rau hauv kev ntxhov siab, khov nyob rau hauv cov yas qhov chaw ntawm cov residual kev nyuaj siab, molecular orientation thiab lwm yam, thiab yog li muab piv nrog thermosetting yas yog ib tug loj shortening tus nqi. , shortening tus nqi ntau, directional pom tseeb, lwm yam shortening tom qab molding, annealing los yog dej txias kev kho mob, lub shortening tus nqi yog feem ntau loj dua cov thermosetting yas.
Thib ob, precision txhaj molding txheej txheem fluidity:
lub fluidity ntawm ntau yam yas kuj hloov vim muaj ntau yam molding yam, lub ntsiab yam tseem ceeb cuam tshuam rau hauv qab no.
① Cov khoom siv kub kub yuav ua rau kom muaj dej ntau ntxiv, tab sis cov yas sib txawv kuj muaj qhov sib txawv.
② precision txhaj tshuaj molding txheej txheem siab nce cov khoom molten yog raug rau shear, liquidity kuj nce, tshwj xeeb tshaj yog PE, POM rhiab heev, yog li nws yog tsim nyog los kho lub txhaj tshuaj los tswj lub liquidity.
③ txhaj tshuaj molding txheej txheem daim ntawv, qhov loj me, layout, txias system tsim, molten cov ntaub ntawv txaus tsis kam thiab lwm yam cuam tshuam ncaj qha cuam tshuam rau qhov tseeb liquidity ntawm cov khoom molten nyob rau hauv kab noj hniav, qhov twg cov khoom molten kom txo qhov kub thiab txias, ua rau kom cov ndlwg tsis kam. lub liquidity yuav raug txo.
Precision qhov chaw txhaj tshuaj molding ua li cas los txhim kho qhov zoo ntawm cov ntsiab lus?
Thib peb, precision txhaj molding ua crystallinity:
thermoplastics raws li nws cov condensation nrog los yog tsis crystallization tshwm sim yuav muab faib ua ob pawg ntawm crystalline plastics thiab non-crystalline plastics, lub thiaj li hu ua crystallization phenomenon yog cov yas los ntawm lub xeev molten mus rau condensation, molecules los ntawm kev ywj pheej txav, kiag li nyob rau hauv ib lub xeev. ntawm tsis muaj kev txiav txim, mus rau hauv lub molecules kom tsis txhob pub dawb txav, raws li ib tug me ntsis taag txoj hauj lwm, thiab ib tug nyiam ua rau lub molecular kev npaj rau hauv ib tug tsis tu ncua qauv ntawm ib tug tshwm sim.
Plaub, precision txhaj molding ua ntawm thermosensitive plastics thiab yooj yim hydrolyzed yas.
Thaum tshav kub kub-rhiab heev yog hais txog qee cov yas muaj qhov kub thiab txias, qhov kub ntawm qhov kub ntawm lub sijhawm ntev dua los yog qhov chaw nres nkoj ntawm qhov chaw me me dhau lawm, cov nyhuv shear yog loj, cov khoom siv kub ua rau muaj kev xav tsis zoo, degradation, decomposition, nrog cov yam ntxwv ntawm cov yas no yog hu ua cov yas uas muaj cua sov.
Tsib, precision txhaj tshuaj molding ua cov khoom ya raws-absorbing plastics nyob rau hauv ntau yam additives.
Yog li cov yas tuaj yeem muab faib ua ob hom dej noo-nqus, dej-nplaum thiab tsis-dej-absorbing, thiab tsis yooj yim rau kev ua raws li cov dej, cov dej ntsiab lus hauv cov khoom yuav tsum tau tswj nyob rau hauv qhov kev tso cai, txwv tsis pub. , ntawm qhov kub thiab txias, cov dej ua roj los yog hydrolysis, kom cov resin blistering, liquidity poob, tsos thiab txhua yam khoom.
Nyob rau hauv cov txheej txheem txhaj tshuaj molding, qhov zoo ntawm kev txhaj tshuaj molded khoom yog ib qho tseem ceeb heev, txawm tias rau cov chaw tsim khoom lossis rau cov neeg siv, yuav ua li cas los txhim kho cov khoom zoo hauv cov txheej txheem txhaj tshuaj molding?
Kev txhaj tshuaj molding txheej txheem pwm kub: txhua qhov kev txhaj tshuaj molded qhov chaw, muaj cov kev txwv kub sab nrauv, yog tias dhau qhov kev txwv no ces ib lossis ntau qhov cuam tshuam thiab cov txiaj ntsig yuav tshwm sim.
Kev txhaj tshuaj ua haujlwm siab: cuam tshuam ncaj qha rau qhov tshwm sim ntawm kev txhaj tshuaj molded qhov chaw, nrog rau cov tsos ntawm smoothness, thiab lwm yam. Yog hais tias lub siab yog tsim los ntawm hydraulic roj, nws yuav cuam tshuam rau kev ceev ntawm resin kev ua si, tab sis yog hais tias lub siab yog tsim los ntawm cov pwm kab noj hniav. , ces nws muaj feem xyuam rau cov tsos ntawm dents thiab wrinkles.
Kev txhaj tshuaj nrawm: nrawm dhau los yog qeeb dhau tsis zoo, yuav muaj kev cuam tshuam tsis zoo rau kev txhaj tshuaj molded qhov chaw, yog li koj yuav tsum xaiv qhov tsim nyog ceev, qee zaum kuj nrog pwm kub, txhaj tshuaj ua rau kev xav dav dav.
MINDWELL tsom rauprecision txhaj molding, nyob rau hauv-tob mastery ntawm in-pwm txhaj IML core technology.
