PPO Thin-Wall High-Speed Process Window
Sorun Belirtisi
【Problem Phenomenon】PPO thin-walled parts high-speed process debugging has poor quality stability
Neden Analizi
SABIC notes that general parameters may not be applicable to special situations such as thin-wall molding and need adjustment; under thin-wall high speed, the melt shear and temperature management window narrows; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
Conduct special debugging of thin-walled parts on the basis of general parameters; take the upper limit of melt temperature to match high speed; lock the process window with cavity pressure monitoring; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
PPO thin-wall high speed is a special process; general parameters only serve as a starting point; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
