Neden Analizi
Insufficient sheet temperature or low mold temperature causes local premature cooling.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Çözüm
①Increase sheet temperature; ②control mold temperature; ③optimize forming timing; ④check the heating system.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Cold mark is a temperature management problem; sheet and mold temperature are controlled in coordination.; 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 problems in the future
