SMMA Processing Temperature Too Low
ظاهرة المشكلة
SMMA products have insufficient filling, flow marks and poor surface quality, with barrel temperature below 190℃.
تحليل الأسباب
SMMA barrel temperature recommended 190-230℃; too low temperature makes melt viscosity high and flowability insufficient; difficult filling and surface flow marks; especially obvious for thick-wall parts.
الحل
①Set barrel temperature 190-230℃; ②take the upper limit for thick-wall parts; ③actually measure melt temperature; ④coordinate with injection speed.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
الخلاصة الأساسية
The SMMA temperature lower limit of 190℃ is the flowability guarantee; thick-wall parts need higher temperature; actual measurement verification prevents display errors.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
