Insufficient product gloss
Fenómeno del problema
The product surface is dull and lusterless, with unacceptable visual effect
Análisis de la causa
Mold cavity surface roughness is insufficient; mold temperature is too low and the melt cannot fully replicate the mold surface; material shrinkage itself causes microscopic unevenness
Solución
Improve mold surface polishing grade to above A1 level; appropriately increase mold temperature to increase the replication rate; adjust holding pressure and time to reduce shrinkage
Conclusión clave
Gloss is influenced by both mold surface quality and process conditions
