SMMA Toughness Degree
Problem Phenomenon
SMMA toughness degree is average, high-impact application limitation.
Cause Analysis
SMMA toughness degree is average; high-impact application limitation; but better than PS; modification improvement; application matching; safety assessment.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
①Application impact assessment; ②modification selection; ③safety standards; ④alternative materials; ⑤matching decision.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
SMMA toughness is an application boundary; modification and substitution are options; assessment keeps safety.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
