Flow marks/water wave marks on product surface
문제 현상
Concentric circular or arc-shaped ripples appear on the surface, spreading like water waves, with irregular distribution
원인 분석
The melt flow front temperature is too low, causing repeated solidification and re-melting; the injection speed curve fluctuates; mold temperature is too low
해결 방법
Increase melt temperature by 5-15°C and mold temperature; use a slow-fast-slow three-stage injection speed curve; enlarge gate size
핵심 요약
Flow marks reflect the unstable state of melt front filling
