Interesting. Usually there is always some material in the barrel - the next few shots so it couldn't be from just sitting there, it would have to have been a combination of pressure, screw speed, barrel temp, etc.? Unless it was sitting for a long time.

My dear friend!! I will like to draw u r kind attention!! To the basic
diff. Of inj. Blow molding with horizntal plastifier!!
In this case!! Screw always returns back to its home position back!! I.e.
Always screw remains at the end position (home position) so the Temp of
hopper throat zone as well its preceding zone!! Which mainly covers a feed
zone!! Has the Most effect on the Melt!! And this is the culprit only!!
So only by changing Temp of these last Two zones could solve the problem!!
Rest all parameters e.g. Inj. P/F, screw speed etc. Remained same!!
In case of any further clarification!! We can surely!! Discuss more!! If,
require any.

You probably have, and I probably overlooked it. My blow molding experience is none.
Sure I would love to be a part of the group.
