PMMA Annealing Temperature Upper Limit
ظاهرة المشكلة
PMMA annealing temperature set at 100℃, products deform and warp
تحليل الأسباب
Annealing temperature close to the heat deflection temperature softens and deforms products during annealing; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based on experience alone.; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
الحل
Annealing temperature controlled at 70-90℃, not exceeding 95℃; properly support products during annealing; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
الخلاصة الأساسية
Annealing temperature must be lower than the heat deflection temperature with margin; 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 future problems.
