ASA extrusion temperature setting
Problem Phenomenon
[Problem phenomenon] ASA extruded sheet and profile surface rough or degraded, temperature setting improper
Cause Analysis
ASA extrusion melt temperature usually 220-260°C, slightly lower than '2079851475616104452; die temperature affects surface finish, too low melt fracture, too high degradation and drooling
Solution
Extrusion melt temperature set at 220-260°C; die temperature matching ensures surface; screen pack pressure differential monitoring prevents degraded material accumulation; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA extrusion 220-260°C lower than '2079851475616104452, die temperature determines surface; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
