Kev txhaj tshuaj molding yog ib qho kev ua lag luam hauv kev tsim khoom lag luam, tab sis kev ua tiav} {{1} discome cov khoom yuav tsum tau mastering series ntawm cov tswv yim siv tswv yim. Cov kev paub hauv qab no los ntawm peb kev xav: cov qauv tsim, cov txheej txheem tsis sib haum, thiab daws teeb meem ntau yam.
Pwm tsim yog qhov tseem ceeb. Lub rooj vag kom tsim nyog thiab qhov loj me cuam tshuam rau pwm. Feem ntau, cov rooj vag yog nyob qhov twg lub phab ntsa tuab yog ib yam kom tsis txhob muaj Weld Mard. Qhov tob ntawm lub tshuab zawj yuav tsum tau tswj hwm ntawm 0.02 thiab 0.05 mm rau ob qho huab cua thiab tiv thaiv cov nyom. Tsis tas li ntawd, cov dej txias kom txias yuav tsum muaj kev sib tw thiab cov khoom sib dhos kom ntseeg tau tias cov khoom siv kub thiab tsawg thiab txo qis shrinkage deformation.
Cov txheej txheem tsis tas yuav tsum muaj kev tswj kom meej. Lub thoob chim yuav tsum tau hloov kho raws li cov khoom siv cov khoom. Piv txwv li, pp khoom siv yog feem ntau teeb tsa ntawm 180 thiab 220 degree. Kev kub dhau ib qho kub yuav yooj yim txi, thaum tsawg dhau qhov kub tau ua rau muaj kev kub siab. Kev txhaj tshuaj siab yog feem ntau tswj hwm ntawm 80 thiab 120 mpa. Thaum tuav theem, lub siab tuaj yeem txo mus rau ib puag ncig 60% kom zam dhau kev ntxhov siab thiab sab hauv kev ntxhov siab. Pwm kub cuam tshuam cuam tshuam cov npoo zoo. Piv txwv li, rau cov pvc cov ntaub ntawv, me me pwm ntawm 80-100 qib tau pom zoo kom tshem tawm cov nyiaj rov qab.
Muaj cov lus qhia rau kev hais txog cov teeb meem sib txawv. Cov cim dab dej feem ntau yog tshwm sim los ntawm tsis txaus tuav lub siab lossis tsis xwm yeem phab ntsa tuab, uas tuaj yeem daws los ntawm kev tuav lub sijhawm lossis txhim kho cov qauv. Flash feem ntau yog tshwm sim los ntawm kev siv lub zog tsis txaus lossis ib qho tsis sib xws ntawm cov nplaim. Txheeb xyuas cov pwm clearance (feem ntau tsawg dua 0.02mm). Npuas tej zaum yuav tshwm sim los ntawm cov khoom siv raw kom qhuav. Hygroscopic cov ntaub ntawv xws li PBT thiab PBT yuav tsum muaj ua ntej-}}}}}}℃for for for at tsawg kawg yog plaub teev.
Mastering Cov tswv yim no tuaj yeem txhim kho cov txiaj ntsig los ntawm kev txhaj tshuaj tuaj. Hauv kev tsim tawm tiag tiag, kev ua kom ua tau zoo dua raws li cov khoom siv cov khoom tseem ceeb, xws li dhau los ntawm kev sim ua kom pom cov kev ua tau zoo tshaj plaws. Nco ntsoov, ib qho txheej txheem ruaj khov yog ib qho tseem ceeb tshaj li nrhiav cov kev tsis sib haum xeeb; Nov yog cov kev paub ntawm kev txhaj tshuaj tshuab moulding.
