ASA Tiger Stripe Light-Dark Pattern
Fenómeno do problema
【Problem Phenomenon】Alternating light and dark tiger stripes on ASA product surface, periodically distributed
Análise das causas
Unstable melt front advancement produces gloss light-dark differences; low melt temperature and mold temperature or filling speed fluctuation are the inducements; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Solução
Increase and stabilize melt temperature and mold temperature; injection speed curve smoothed; check plasticizing feed stability; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusão principal
ASA tiger stripes are front instability, temperature and speed dual stabilization; after confirming effectiveness, fix 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
