PET recycled '2079851475616104452
Sorun Belirtisi
Large fluctuations in impact strength of rPET injection molded parts
Neden Analizi
Recycled material has large batch-to-batch differences in IV value and varying degrees of degradation, causing mechanical properties to fluctuate accordingly; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Test incoming material IV value and use in batches; adjust blending ratio according to IV value; toughening modification compensation; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
rPET '2079851475616104452 manages performance by IV value grading; after confirming effectiveness, fix 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
