Problembeschreibung
【Problem Phenomenon】PPO extruded large products deform or stress crack after storage
Ursachenanalyse
PPO extruded products generally need post-treatment, especially large products: heat at a temperature about 10℃ lower than the use temperature for 24 hours to reduce or eliminate internal stress
Lösung
Post-treat large extruded parts according to the use temperature -10℃×24h procedure; cool slowly after post-treatment; measure and compare dimensions of critical parts before and after post-treatment; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Wichtigste Erkenntnis
PPO extruded large part post-treatment is baking for 24 hours at use temperature minus 10℃; 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 subsequent similar problems
