Fenómeno del problema
The surface gloss of PET injection molded products is insufficient, showing a matte or rough state.
Análisis de la causa
The mold surface roughness is poor and not polished to a mirror finish; melt temperature is on the low side and replication is poor; mold temperature is low with rapid cooling.
Solución
Polish the mold to a mirror finish Ra≤0.05μm; increase melt and mold temperature; strengthen drying; increase injection pressure and speed.
Conclusión clave
High gloss of PET products requires mirror molds, high-temperature processes and clean raw materials.
