PPO Multi-Cavity Imbalance
Sorun Belirtisi
[Problem Phenomenon] Large differences in weight and dimensions of products from each cavity of PPO multi-cavity molds
Neden Analizi
High-viscosity melt is more sensitive to runner balance; runner size differences and uneven temperature make filling inconsistent among cavities; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Runner balance design and correction; uniform temperature among cavities; SPC analysis of weight and dimensions by cavity number; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PPO multi-cavity balance relies on precise runner correction, and SPC by cavity number locates differences; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
