PC Product Surface Flow Marks
Fenómeno del problema
Visible wavy flow marks on the PC product surface, obvious on high-gloss surfaces.
Análisis de la causa
Front temperature drops too fast or injection speed fluctuates; low mold temperature and a small gate cause unstable filling.
Solución
①Increase mold temperature and melt temperature; ②Optimize the speed curve to keep the front stable; ③Enlarge the gate; ④Check hot runner temperature uniformity.
Conclusión clave
Flow mark treatment = constant front temperature and speed.
