PPS product molding cycle
Problem Phenomenon
Cycle optimization.
Cause Analysis
PPS crystallizes fast and the cycle has room for optimization; but high-temperature setting must be sufficient.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Calculate setting time; ②optimize temperature management; ③stepwise compression verification; ④monitor quality.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Cycle optimization must not sacrifice crystallization setting.; 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
