Die spray streaking is a nozzle distance problem
PourA413Surface4/5 confidence
What we learned
What worked
Thinning the ratio to 1:90 and fixing nozzle distance at 180mm. Streaking on the sealing face stopped.
What failed
Thinning the ratio alone. The streaks moved but did not clear until the distance was fixed too.
War story
Two variables, changed one at a time, took two shots instead of one to find. Worth it. Changing both at once would have left us not knowing which mattered.
