ASA melt index 15g/10min
Problem Phenomenon
ASA melt flow rate 15g/10min, flowability management.
Cause Analysis
ASA melt flow rate 15cm³/10min (220°C/10kg); flowability; processing window; filling capability; process matching; grade selection.
Solution
①Melt index 15 reference; ②flowability evaluation; ③process matching; ④filling management; ⑤grade selection.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA melt index is a flowability indicator; process matching ensures quality; selection ensures application.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
