ASA screw speed medium
Problembeschreibung
[Problem phenomenon] ASA screw speed too high causes excessive plasticization shear, too low causes insufficient feeding
Ursachenanalyse
ASA recommends medium screw speed: high speed shear heat and glass fiber grade fiber breakage risk, low speed slow plasticization; medium speed with external heat plasticization is most stable; during on-site investigation, verify item by item according to this mechanism, avoid blindly adjusting the machine based on experience alone
Lösung
Screw speed set at medium speed; glass fiber grades lower to preserve fibers; plasticization fluctuations check heater bands and compression ratio; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Wichtigste Erkenntnis
ASA screw medium speed is the norm, external heat primary shear secondary; 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
