PP Injection Part Gloss Deficiency
Fenómeno del problema
PP parts are overall dull and not bright.
Análisis de la causa
Low mold temperature and insufficient holding pressure cause poor surface replication; low mold polish grade; some grades are inherently matte.
Solución
①Raise mold temperature and holding pressure; ②upgrade cavity polishing; ③confirm grade gloss characteristics; ④improve venting.
Conclusión clave
Gloss = replication + mold + grade, three elements.
