Manufacturing process of this part???
(OP)
Does anyone know the manufacturing process of this bottle? I had thought it was just blow molded but then someone asked "how do they make the handle"? and suddenly i was stumped?
How would you make the hollow handle in a mold type process? Cant think of how to do it with either blow molding or injection molding?
Does anyone have any clue?
Thanks

I.e., before inflation, the precursor is an extruded tube of ovoid cross section. You can see a fold in the bottle's bottom at the parting line that suggests the width of the parison is most of the bottle's diameter. I think the parison is inflated a little and bellied out a bit to ensure there's material for the handle, then the mold is closed and the parison is inflated against it.
Double-necked jugs are made the same way, but cut off halfway down the 'handle' to make two necks.

Milk jugs will often show up at the store with the piece of material inside the handle not completely removed showing they are blow molded.

Blow molding without the angled handle is obvious.. but with the handle no so much.
Thanks for your help!

Pretty sure it's blow molded.

Mike Halloran described the way that the parison is handled within the blow molding process in order to produce hollow articles with handles.
