Kub khiav aging drift ncaj qha ua rau uncontrolled yas yaj kub thiab uneven pwm filling. Qhov no, ntawm qhov tod tes, ua rau muaj qhov tsis xws luag xws li kev txhaj tshuaj luv luv, flash, qhov sib txawv ntawm qhov sib txawv, thiab qhov tsis sib xws ntawm cov kev ntxhov siab sab hauv- ua rau muaj kev cuam tshuam loj heev rau cov khoom muag, kev sib dhos precision, thiab kev ntseeg siab ua haujlwm. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev siab- nrawm, nyias- phab ntsa, thiab siab- cov ntawv thov molding precision, qhov twg txawm tias qhov ntsuas kub sib txawv tuaj yeem nthuav dav rau hauv qhov systemic, batch- qhov teeb meem zoo.
1. Cov ntsiab lus tseem ceeb ntawm cov khoom tsis zoo
Short Shots (Kev Sau Tsis tiav)
Kev laus ua rau qhov kub thiab txias ntawm cov lus qhia nozzle poob, ua rau muaj zog yaj viscosity thiab txo flowability. Thaum lub sij hawm siab - ceev filling, lub yaj tsis ua kom tiav cov kab noj hniav hauv lub sijhawm; Qhov teeb meem no tshwj xeeb tshaj yog nyob rau hauv cov pwm featuring ntev, slender runners los yog ntau kab noj hniav.
Flash (Hloov Overflow)
Localized overheating los yog siab fluctuations ua rau cov yaj mus dhau ntawm cov pwm parting kab los yog ejector tus pin qhov chaw, tsim burrs. Qhov no yuav tsum tau ua haujlwm trimming ntxiv, yog li nce nqi ntau lawm.
Tsis ruaj tsis khov Dimensional raug
Kev faib tawm tsis sib xws ua rau muaj qhov sib txawv ntawm qhov ntim ntawm cov kab noj hniav sib txawv, uas ua rau qhov tsis sib xws ntawm qhov shrinkage. Qhov no ua rau qhov sib txawv ntawm qhov sib txawv ntawm cov khoom nyob rau hauv tib lub batch, cuam tshuam cov txheej txheem sib dhos ua haujlwm thiab ua rau cov khoom siv hluav taws xob tsis tuaj yeem nkag / rho tawm quab yuam tshwj xeeb.
Internal Stress thiab Warpage
Tsis sib npaug txias thiab tsis sib xws tuav lub siab ua kom cov kev ntxhov siab nyob hauv qhov molded. Thaum demolding, ib feem dhau mus ua tsov rog lossis deformation-ib qho tshwm sim tshwj xeeb tshaj yog nyob rau hauv nyias- cov khoom siv phab ntsa.
Lub rooj vag tsis zoo thiab kev zoo nkauj tsis zoo
Kub drift nyob rau hauv lub rooj vag cheeb tsam feem ntau ua rau muaj kev tsis xws luag xws li txias slugs, stringing, flow marks, los yog hazy chaw. Cov imperfections no cuam tshuam ob qho tib si qhov muag pom ntawm cov khoom thiab nws cov sealing kev ncaj ncees.
2. Ripple Effects ntawm Cov Txheej Txheem Ntau Lawm

Kev poob qis hauv Yield Rate |
Cov khoom seem nce los ntawm 1–3%-muaj peev xwm tshaj 5% rau siab -cov khoom lag luam- ncaj qha eroding cov nyiaj tau los. |
|
Nrawm txheej txheem Tuning |
Kev hloov kho tsis tu ncua (piv txwv li, qhov kub thiab txias, kev txhaj tshuaj nrawm) yog yuav tsum tau "compensate" rau qhov system drift, yog li nce nqi ntawm lub tshuab teeb. |
|
Ntxiv Downtime rau Kev Kho |
Qhov zaus ntawm kev tshem tawm cov pa roj carbon monoxide thiab hloov cov cua sov bands / thermocouples nce, cuam tshuam tsis zoo rau OEE (Txhua Yam Khoom Siv Tau Zoo). |
|
Nyuaj hauv Cov Khoom Taw Qhia Tshiab |
Cov txheej txheem kev laus tawm tsam kom ruaj khov kom haum rau cov txheej txheem tshiab qhov rais, ncua kev nce qib ntawm cov khoom loj. |
Kev Tshawb Fawb Txog Kev Tshawb Fawb: Ib lub chaw tsim khoom siv tsheb sib txuas tau pom tias lub tshuab hluav taws xob kub uas siv rau ntau tshaj rau xyoo tau ntsib qhov kub thiab txias ntawm ± 6℃thaum lub caij ntuj no. Qhov no ua rau muaj qhov nce ntawm qhov tsis xws luag rau kev ntxig / rho tawm quab yuam-tshwj xeeb rau 0.8mm nplua- suab txuas- nce los ntawm 0.2% mus rau 1.5%. Tom qab hloov lub kaw lus, tus nqi tsis raug rov qab mus rau hauv 0.18%.
