What are the bits of plastic that are cut off and disgarded after the moulding process?
I think it's a word like scree or scrag?

I think the most common term is flashing.

Flashing is one of the bits you cut off. That's the bits that leak into gaps that aren't meant to be in the mould.
But I was think of the bits that are deliberatley moulded and then disgarded...
Sprigs maybe? The "sticks" that hold the pieces together.
I used to work in a plastic moulding factory while I was a student and it's bugging me that I can't remember!
Sorry I'm not explaining this well...

I guess you cut off and discard both flashing and sprules. (sp?) Runners too, the sections coming out of the molding machine and distributing the plastic to the sprules.

For a while, I managed a small vinyl compounding plant. Most of the pellets we made were extrusion grade, but we spent about one week a month producing molding compound. I saw all the stuff in the scrap returned for reprocessing.

Nice thing about this site is how easy it is to try again.

Thank you, that's been driving me nuts for months!

Like I said, it is easy to try again. I thought to look in the dictionary, and it was there, but no ''l''. It has been about 20 years since I worked in the plastic industry.

Thank you for you comment and rating. Unfortunately, it looks like somebody else gave it a bad rating. I have offended some here, and they are risking confusing people coming here for answers by giving mine bad ratings.

Anybody with a dictionary can verify that sprue is the correct term. If somebody wanted to correct my original spelling, they should have posted it where you could see it. I am here to help. I am not sure what the agenda is of those giving my helpful answers bad ratings.

That was very mean of them.
Did they say why the bad rating? It would be much more helpful if people posted spelling corrections etc instead of rating badly..
