[Problem Phenomenon] Feasibility and precautions for recycling PPO products
Neden Analizi
PPO regrind can be used but must be clean to prevent contamination; drying time needs to be extended due to particle size differences, and it may affect color; the use of regrind is restricted for regulatory certified parts (drinking water, UL)
Çözüm
Clean the regrind and extend drying time; limit the regrind ratio for color-sensitive parts; evaluate regrind permission for certified parts according to regulations; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PPO regrind can be used with particular care: cleanliness, drying and color are the three gates; 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
