Injection Speed Curve Mismatch in PBT '2079851475616104452
ظاهرة المشكلة
The multi-stage injection speed setting does not match the actual filling process, causing filling defects.
تحليل الأسباب
The speed stage positions and speed values are set based on experience rather than filling analysis, and sudden speed changes produce appearance defects.
الحل
Use mold flow analysis to determine the speed switching positions; optimize the speed curve so that the melt front advances at a uniform speed.
الخلاصة الأساسية
PBT multi-stage injection requires precise consideration of the filling process.
