①Thoroughly clean the hopper and barrel; ②standardize the material change process; ③classified management of recycled material; ④check the cleanliness of the storage and conveying system.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Delamination mostly originates from material contamination; clean management and standardized material change are the root of prevention.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
