PARA Surface Gloss
Problem Phenomenon
PARA high-gloss surface quality is unstable; multiple influences of glass fiber, temperature and speed.
Cause Analysis
High gloss is a PARA characteristic but glass fiber influences it; mold temperature and injection speed; surface replication; material batches.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solution
①Optimize mold temperature and injection speed; ②Surface replication management; ③Batch consistency; ④Gloss inspection.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Refined process management for PARA high-gloss surfaces; temperature-speed balance; inspection ensures consistency.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
