PPO Shot Size and Barrel Capacity
Sorun Belirtisi
【Problem Phenomenon】Processing PPO with a small machine at full shot or a large machine at small shot, product quality is unstable
Neden Analizi
The NHP9023 data sheet requires shot size to be 30-70% of barrel capacity; too low means long residence time and high degradation risk, too high means insufficient plasticization; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
Match the machine with shot size at 30-70% of barrel capacity; change machine size if out of range; calculate residence time to verify thermal safety; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
PPO shot size 30-70% is the machine matching benchmark; both ends produce quality problems; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
