MP poor surface gloss
Fenómeno del problema
MP product surface gloss <60%, below the 80% requirement, dull appearance
Análisis de la causa
mold surface rough Ra>0.4μm; MP high crystallinity, surface microcrystals scatter light; cooling rate improper
Solución
1) polish the mold to Ra<0.1μm mirror finish; 2) raise mold temperature to delay crystallization and reduce scattering; 3) add nucleating agent to control crystal size
Conclusión clave
poor gloss is caused by mold roughness and crystal scattering; polishing the mold and controlling crystallization are key
