PS '2079851475616104452 Temperature Window
Problem Phenomenon
Product quality varies greatly between different machines.
Cause Analysis
Although the PS processing temperature window is wide, transparent parts are sensitive to temperature; machine temperature control differences affect quality.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
①Unify the measured melt temperature benchmark; ②calibrate thermocouples; ③establish process cards; ④test by batch.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Cross-machine consistency relies on the measured benchmark; standardized management is the guarantee.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
