Injection Molding

Carbon fiber reinforced PEEK narrower processing window
ظاهرة المشكلة
The injection conditions of CF/PEEK composite materials are more demanding than those of pure PEEK
تحليل الأسباب
The extremely high thermal conductivity of carbon fiber makes the melt cool faster in the cavity; CF greatly increases the apparent viscosity of the melt; CF wears the screw and mold more severely
الحل
On the basis of pure PEEK, further increase the mold temperature (about 10°C) to compensate for carbon fiber heat conduction; select screws and mold steels with higher wear resistance grades; enlarge gate and runner dimensions
الخلاصة الأساسية
CF reinforcement expands the performance of PEEK but also greatly increases processing difficulty
