Glass Fiber Agglomeration in PBT Injection-Molded Parts
ظاهرة المشكلة
Glass fiber gathering areas (glass fiber clusters) appear locally in the product, and the performance of this area is abnormal.
تحليل الأسباب
The glass fiber masterbatch or reinforced material is not fully mixed; the screw mixing is insufficient; the glass fiber separates and deposits during injection.
الحل
Use uniformly mixed reinforced material; optimize the screw mixing section design; appropriately adjust the back pressure.
الخلاصة الأساسية
