PPS product surface gloss
Problem Phenomenon
Insufficient surface gloss.
Cause Analysis
Low mold temperature or mold surface condition; surface replication of PPS under high mold temperature needs management.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Optimize mold temperature; ②polish the cavity; ③clean the mold surface; ④stabilize the process.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
Gloss relies on mold temperature and mold surface management.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
