Suresh,
Looks like there are notes on the side. They are all valid. The plastic is not flowing easy and evenly.

I have seen some strange flow marks that only got better with a hot mold....have you tried mold temps at 180 or hotter.... (not higher than your water lines will take though!)

I see that according to UL prospector, you should be aiming at a mold temp between 160 - 200F. I would attempt to hold at 190.
