Deposits on mold cavity surface
Problem Phenomenon
A white or brown deposit layer appears on the mold cavity surface, affecting product appearance
Cause Analysis
Low-molecular-weight additives precipitate and condense at high temperature; material degradation products condense on the cavity surface; excessive release agent spraying accumulates
Solution
Optimize the formulation to reduce low-molecular substance addition; regularly clean the mold (every 3000-5000 shots); control the spraying method and dosage of release agent
Key Takeaway
Mold deposits affect product surface quality and mold maintenance cycle
