PP Barrel Temperature Gradient
Sorun Belirtisi
[Problem Phenomenon] PP barrel temperature settings jump, resulting in uneven plasticizing
Neden Analizi
PP barrel progressive zoning: rear section 180-200°C, middle section 200-230°C, front section 220-250°C, nozzle 230-260°C; progressive heating ensures uniform plasticizing and prevents local overheating
Çözüm
Set according to the progressive curve; nozzle slightly lower than the front section to prevent drooling; calibrate with actual melt temperature measurement; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Temel Çıkarım
PP barrel heats progressively, with the nozzle slightly lower to prevent drooling; 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 similar future problems
