Yuav ua li cas los daws qhov teeb meem ntawm pos huab ntxoov ntxoo nyob rau hauv ib sab ntawm lub preform nyob rau hauv lub preform txhaj molding?
Cov txheej txheem hauv qab no tuaj yeem siv los daws qhov teeb meem ntawm cov duab ntxoov ntxoo ntawm ib sab ntawm lub preform thaum lub sij hawm preform txhaj molding txheej txheem:
1, Kho qhov txhaj tshuaj kub
Kev teeb tsa cov ntsia hlau txhaj tshuaj kub siab dhau yuav ua rau cov ntaub ntawv nyoos yaj ntau dhau lossis txawm tias carbonize, cuam tshuam rau cov khoom lag luam zoo thiab yog li tsim cov duab ntxoov ntxoo. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau txo qhov kub thiab txias ntawm kev txhaj tshuaj molding tshuab ntsia hlau raws li lub hauv paus chiv keeb thiab hom PET raw khoom kom nce qib melting ntawm cov yas thiab zam kom tsis txhob muaj qhov pom ntawm pos huab.
2. Kho qhov txhaj tshuaj ceev
Kev txhaj tshuaj nrawm nrawm heev yuav tiv thaiv cov khoom siv raw hauv lub xeev molten los ntawm kev sib xyaw ua ke hauv cov pwm preform, ua rau cov duab ntxoov ntxoo ntawm cov khoom thiab yooj yim ua rau cov pwm preform. Los ntawm maj mam txo qhov kev txhaj tshuaj nrawm, cov khoom siv PET molten tuaj yeem ua tiav hauv cov pwm preform los txhim kho cov nyhuv ntawm cov khoom.
3. Kev saib xyuas tsis tu ncua ntawm cov cuab yeej txhaj tshuaj molding
Kev ua haujlwm ntawm cov cuab yeej txhaj tshuaj molding ncaj qha cuam tshuam rau cov khoom zoo, xws li clamping quab yuam, txhaj tshuaj ntim, thiab lwm yam. Lub tshuab txhaj tshuaj molding yuav tsum tsis tu ncua thiab kho kom muaj kev ruaj ntseg ntawm ntau yam kev ua yeeb yam ntawm cov cuab yeej, yog li zam qhov teeb meem ntawm fogging los ntawm cov khoom siv.
4. Siv cov khoom zoo - PET zoo
Qhov zoo ntawm cov khoom siv PET kuj yog qhov tseem ceeb cuam tshuam rau kev nyab xeeb. High - cov khoom zoo thiab ruaj khov PET yuav tsum raug xaiv. Yog tias cov khoom siv rov ua dua yog sib xyaw ua ke hauv kev tsim khoom, Nws yuav tsum tau tswj nyob rau hauv ib qho kev faib ua feem, thiab qhov zoo thiab huv si ntawm cov khoom siv rov ua dua yuav tsum tau lav. Zam tsis txhob muaj teeb meem los ntawm cov khoom siv PET.
Hauv cov ntsiab lus, qhov teeb meem ntawm qhov kub hnyiab ntawm ib sab ntawm preform thaum lub sij hawm preform txhaj tshuaj molding txheej txheem tuaj yeem daws tau zoo los ntawm kev kho qhov kub thiab txias, kev txhaj tshuaj ceev, kev tu cov cuab yeej siv tsis tu ncua, thiab siv cov khoom zoo siab - zoo PET thiab lwm yam.
