    Only if surface condition is the cause. Polishing does not correct hesitation, gate jetting or an unstable thermal boundary and can change optical form.<\/p>\n

    Why does the mark return after maintenance?<\/h3>\n

    Cleaning, reassembly, cooling connection, vent condition or hot-runner balance may have changed. Compare cavity and process records before and after the event.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"

    Flow marks in injection molding often return because a process change moves the visible line without removing the mechanism. The mark may record a cold flow front, hesitation, gate jetting, unstable velocity, thickness transition or surface replication difference. To correct it permanently, relate the mark to fill position and geometry before changing temperature or speed. Fastest useful test: make a short-shot sequence and overlay the visible mark on the advancing flow front. If the mark follows a hesitation or reacceleration point, the part geometry and velocity profile are already telling you where to investigate.
