Molds & Tooling

Insufficient product gloss
Problem Phenomenon
The product surface is dull and lusterless, with unacceptable visual effect
Cause Analysis
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
Solution
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
Key Takeaway
Gloss is influenced by both mold surface quality and process conditions
