Nyob rau hauv cov ntaub ntawv ntawm huab cua kab los yog dav hlau kab nyob ze ntawm cov roj hmab inlet ntawmtxhaj tshuaj molded qhov chawthaum lub sij hawm tsim khoom, cov kev ntsuam xyuas hauv qab no tuaj yeem raug xa mus rau kev sib piv thiab kev txhim kho.Ntawm lawv, txo qhov kev txhaj tshuaj nrawm yog qhov tseem ceeb rau peb txhawm rau txhim kho qhov teeb meem ntawm cov kab txhaj tshuaj thiab cov kab cua, thiab qhov thib ob yog los xyuas seb qhov loj ntawm qhov txhaj tshuaj molding ib feem ntawm cov roj hmab inlet me dhau los yog nyias dhau.Ci cov ntaub ntawv zoo raw khoom yog qhov kev ua haujlwm yooj yim kom ntseeg tau tias ntau lawm, thiab yuav tsum ua kom zoo.
Muaj qee qhov sib txawv ntawm qhov pom ntawm cov kua nplaum inlet cua kab thiab dav hlau kab los ntawm ntau yam laj thawj.Ua tib zoo saib xyuas ntawm lub sijhawm zoo tib yam, uas tuaj yeem ua kom nrawm rau kev tsom xam thiab kev daws teeb meem.
Yog cov ntaub ntawv raw rauPCntau lawm tau ci tag nrho, los yog yuav muaj cua lossis tua kab ntawm cov dej nkag, cov hauv qab no yuav tsum tau xav txog:
1. Thawj qib kua nplaum txhaj tshuaj nrawm heev.Qhov no yog qhov laj thawj tseem ceeb rau lub cim huab cua thaum nkag mus rau hauv dej.Nws ua rau eddy tam sim no loj heev thaum cov nplaum nplaum nkag mus rau hauv cov kab noj hniav, ua rau eddy pa cim.Yog li ntawd, qhov no yog thawj zaug uas tus shunter yuav tsum xav txog thiab sim txo qhov ceev.
2. Cov roj hmab inlet yog nyias lossis nyias dhau, uas kuj yog ib qho tseem ceeb ua rau huab cua thiab tua cov cim.Vim hais tias cov kua nplaum inlet me dhau los yog nyias dhau lawm, nws yuav ua rau cov kua nplaum nrawm nrawm ntawm cov kua nplaum nkag mus rau hauv cov pwm kab noj hniav nrawm dhau, ua rau cov kab dav hlau thiab cov kab cua, uas yog qhov ua rau cov kab nab.Yog li ntawd, yog tias qhov teeb meem tsis tuaj yeem raug tshem tawm txawm tias qhov ceev tau raug txo kom qis dua, nws yuav tsum tau txiav txim siab seb cov dej nkag los yog nyias dhau los yog nyias, xws li tsawg dua 0.5mm lossis me dua.
3. Lub thickness ntawm phab ntsa ntawm cov tshuaj molding ib feem ntawm cov roj hmab inlet, nws yog yooj yim dua los tsim cov huab cua wrinkles, xws li ntau tshaj 4 hli.Vim tias cov phab ntsa tuab tuab dua, qhov yooj yim dua nws yog tsim kom muaj eddy tam sim no thaum cov nplaum nplaum nkag mus rau hauv dej inlet, uas ua rau lub cim ntawm huab cua ripple.Nyob rau hauv cov ntaub ntawv no, nws yog ib qho nyuaj rau tshem tawm cov huab cua ripple los ntawm enlarging cov dej inlet thiab txo qhov ceev.Lub sijhawm no, nws yog qhov zoo dua los hloov cov roj hmab nkag mus rau qhov chaw uas muaj cov phab ntsa nyias nyias, xws li qhov chaw hauv qab 3 hli.
4. Qhov ci ntsa iab ntawm qhov chawpwmkab noj hniav, uas yog, qhov ci ntsa iab ntawm qhov chaw txhaj tshuaj molding yog, qhov yooj yim dua nws yog tsim kom muaj huab cua wrinkles.Yog tias qhov kev txhaj tshuaj molding yog ci dhau lawm, cov kab cua me me yuav tshwm sim.
5. Yog tias qhov kub ntawm cov nplaum nplaum los yog cov pwm qis dhau lawm, cov khoom txhaj tshuaj molded tseem yuav muaj cov kab txhaj tshuaj los ntawm cov gel, nrog rau cov kab tsis zoo.
6. Rau cov khoom siv raw uas yooj yim rau hlawv, yog tias qhov kub ntawm cov yaj yog siab dhau lawm, cov cua ripple tshwm sim los ntawm cov roj decomposition ntau dhau yuav tshwm sim.
7. Qhov zoo ntawm cov kua nplaum yuav tsum tau lees paub.Lub siab rov qab ntawm cov khoom siv PC yuav tsum tau teem rau ntawm 10bar ~ 25bar.Qhov ceev ntawm cov kua nplaum melting yuav tsum tau teem rau nruab nrab ceev.Cov kua nplaum rho tawm yuav tsum tsis txhob ntev dhau.Txwv tsis pub, yog tias huab cua nkag mus rau hauv rab phom phom, cov khoom yuav muaj tshuaj tsuag.Cov kua nplaum extraction stroke yuav tsum tau teem raws li nram qab.Qhov siab dua lub nraub qaum yog, qhov ntev ntawm cov kua nplaum tshem tawm tau teeb tsa, feem ntau 2mm ~ 10mm.
8. Qhov kub ntawm lub nozzle yog siab dhau los yog qis heev.Yog tias nws siab dhau lawm, cov roj hmab ntawm lub nozzle yuav decompose thiab tsim cov kab cua;Tsawg dhau lawm, kev txhaj tshuaj tsis du, tsim cov kab dav hlau, lossis txias offset luam ntawv.
