II. Targeted Solutions
1. Txhim kho qhov ntsuas kub tswj qhov ntsuas kub kom txo tau qhov kub thiab txias oscillations
Ua haujlwm siab -Cov Tswj Kub Kub Precision: Xaiv qhov ntsuas kub tswj modules nrog PID tus kheej-tuning lossis fuzzy logic tswj kom txo tau overshoot thiab hysteresis.
Optimize Thermocouple Installation Positions: Xyuas kom ntseeg tau tias kev sib cuag ntawm qhov ntsuas kub thiab cov phaj khiav, nrog rau qhov ntsuas qhov ntsuas tsawg dua lossis sib npaug li 10 hli los ntawm phab ntsa khiav thiab nyob hauv nruab nrab ntawm thaj chaw tswj kev kub ntxhov.
Muab cov khoom cua sov kom sib npaug: Ua kom cov cua kub ceev ntawm qhov sib txuas ntawm cov ceg khiav thiab cov neeg ua haujlwm tseem ceeb, thiab nyob ze ntawm lub rooj vag, kom tsis txhob muaj qhov sib txawv ntawm qhov kub hauv zos.
2. Txhim kho cov qauv kub khiav kom tshem tawm qhov chaw tuag
Tsis txhob Runner Dead Zones: Hloov cov qauv tsim kom tshem tawm cov chaw nyob ruaj khov, tiv thaiv cov khoom seem los ntawm kev ua kom sov ntev ntev, ua rau degradation lossis kub lag.
Hloov lub rooj vag loj: Tsim nyog nce lub rooj vag txoj kab uas hla nyob rau hauv kev tso cai txwv kom txo shear tshav kub tiam thiab txo lub sij hawm scorching tshwm sim los ntawm overheating.
Taw qhia ntawm Elastic Flow-Limiting Nplhaib: Raws li tau piav qhia hauv Bokang Mould patent, elastic flow-limiting nplhaib yog ntsia rau ntawm qhov tso zis kawg ntawm lub manifold kom tsis txhob ntws fluctuations thiab txhim kho kev ruaj khov.
3. Ntxiv Sensors rau kaw -Loop Control:
Dual Sensor Monitoring: Thawj thiab thib ob sensors tau nruab rau ntawm cov pwm core nto thiab qhov kub khiav tawm qhov kawg, raws li, los muab qhov tseeb - lub sij hawm tawm tswv yim ntawm qhov kub thiab txias hloov, uas yog tom qab ntawd hloov kho los ntawm kev tswj hwm.
Pwm Cavity Pressure Feedback: Cov ntsuas ntsuas siab tau teeb tsa hauv txhua qhov kab noj hniav txhawm rau saib xyuas lub siab siab thiab qhov sib lawv liag thaum lub sijhawm sau cov txheej txheem, kom pom qhov tsis txaus txaus.
Siv Kev Siv Ceev Hloov Siab Rau Kev Tuav Siab: Thaum cov pwm tau ntim rau 80% ~ 90%, qhov ceev tau hloov mus rau qhov qis qis (10% ~ 20% ntawm qhov qub ceev) kom tsis txhob muaj qhov siab siab siab nyob rau hauv thawj zaug filling kab noj hniav thiab ua tiav lub siab tuav.
4. Stabilizing Raw Materials thiab Txheej Txheem Ib puag ncig:
Preheating Thaum tshav kub kub- Cov ntaub ntawv rhiab heev: xws li PVC thiab TPE, kom txo tau qhov cuam tshuam ntawm qhov sib txawv ntawm qhov kub thiab txias ntawm melt flowability.
Tuav lub Cuab Yeej Txias Txias: Tsis txhob cuam tshuam cov thermal load cuam tshuam los ntawm lub sijhawm pib - nres lub voj voog ntawm cov dej txias.
Tuav lub Cuab Yeej Txias Txias: Tsis txhob cuam tshuam cov thermal load cuam tshuam los ntawm lub sijhawm pib - nres lub voj voog ntawm cov dej txias. Kev tu thiab tu tsis tu ncua: Tshem tawm cov pa roj carbon deposits thiab degradation cov khoom los ntawm cov ndlwg channel los tiv thaiv lub sij hawm blockages los ntawm kev hloov nyob rau hauv lub zos ndlwg tsis kam.
