ASA Extrusion Processing Guide
Problem Phenomenon
ASA extrusion processing temperature 240-280℃, drying 80℃×2-4h.
Cause Analysis
ASA extrusion processing guide; drying temperature 80℃ time 2-4 hours; mold temperature 60℃; melt temperature 240-280℃; injection speed 200mm/s; initial low temperature setting to avoid degradation and material hang-up; purge material before shutdown.
Solution
①Drying 80℃×2-4h; ②mold temperature 60℃; ③melt temperature 240-280℃; ④initial low temperature; ⑤purge material at shutdown.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
The drying, temperature and speed of the ASA extrusion guide are standards; initial low temperature prevents degradation; purging keeps clean.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
