Internal bubbles and shrinkage cavities of PMMA thick-walled parts
ظاهرة المشكلة
Shrinkage cavities or vacuum bubbles appear in the center of thick-walled PMMA products.
تحليل الأسباب
The outside cools and solidifies first, hindering center feeding; insufficient holding pressure forms shrinkage cavities.
الحل
Extend holding pressure time; optimize gate size to delay freezing; staged holding pressure.
الخلاصة الأساسية
PMMA thick-walled shrinkage cavities are the result of insufficient holding pressure.
