PET dryer selection
Sorun Belirtisi
Purchasing a drying system for a PET sheet line, the supplier proposals differ greatly
Neden Analizi
PET drying requires high temperature, large air volume, and low dew point, and the capacity of ordinary plastic dryers does not match; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
Calculate the drying capacity according to output, initial moisture content, and target moisture content; select a PET-specific drying system with crystallization function; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PET drying systems must be specially selected according to process parameters; after confirming effectiveness, solidify 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
