PCABS Flow Marks
Fenómeno do problema
PC/ABS flow marks are caused by poor material flow, have a different appearance from silver streaks, and are not caused by moisture decomposition.
Análise das causas
PC/ABS flow marks occur during injection; poor material flow; unlike silver streaks, they are not caused by moisture or decomposition; appearance differences; influenced by temperature, speed, and mold.
Solução
①Increase material temperature to improve flow; ②appropriately increase mold temperature; ③reduce injection speed; ④differentiate diagnosis from silver streaks; ⑤comprehensive adjustment.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusão principal
The differential diagnosis of PCABS flow marks and silver streaks is the key; temperature, speed, and mold are the adjustment directions; avoid misjudgment.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
