ABS amorphous management logic
Problembeschreibung
[Problem phenomenon] Managing ABS process with crystalline material thinking, parameters misplaced
Ursachenanalyse
ABS is amorphous: no crystalline melting point, uniform shrinkage 0.4-0.7%, mold temperature affects surface stress rather than crystallinity; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Lösung
Set the process according to amorphous logic; mold temperature serves surface stress; uniform shrinkage compensation; 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
Wichtigste Erkenntnis
ABS amorphous material, mold temperature manages surface and shrinkage is uniform; 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
