PPS Short Shot and Material Shortage
Problembeschreibung
Incomplete filling of thin-walled products.
Ursachenanalyse
Low melt temperature or mold temperature causes PPS to solidify prematurely; insufficient injection pressure and speed or poor venting also cause short shot.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Lösung
①Increase melt and mold temperatures; ②increase injection pressure and speed; ③improve venting; ④enlarge gates and runners.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Troubleshoot PPS short shot from temperature, pressure and venting; solidification speed management of high-temperature materials is the key.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
