ASA mold temperature surface quality balance
Problembeschreibung
[Problem phenomenon] ASA mold temperature too low causes rough surface and obvious weld lines, too high extends the cycle
Ursachenanalyse
ASA mold temperature 40-80°C (Plasthub recommends 50-80°C): the upper limit obtains the best surface finish and weld line quality, but extends cooling; for amorphous materials, mold temperature mainly affects surface rather than crystallization
Lösung
Appearance parts take mold temperature upper limit 60-80°C; structural parts take 40-60°C to preserve cycle; independent temperature control of front and rear molds compensates wall thickness differences; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Wichtigste Erkenntnis
ASA mold temperature 40-80°C, appearance takes upper limit structure takes lower limit; 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
