PMMA Injection Temperature Window Management
ظاهرة المشكلة
Light transmittance fluctuates between product batches, and measured melt temperature deviation among machines is large.
تحليل الأسباب
PMMA light transmittance is temperature-sensitive; locking the 235±5℃ window can stabilize transmittance ≥91.5%; machine temperature control differences directly cause batch fluctuations.
الحل
①Unify melt temperature window settings; ②calibrate thermocouples of each machine; ③test light transmittance and YI batch by batch; ④archive stabilized process parameters.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
الخلاصة الأساسية
Temperature window standardization is the guarantee of PMMA optical quality consistency; measured melt temperature uses a unified benchmark, and parameter archiving facilitates traceability.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
