(...) I would guess that you are correct. I, and other people (IIRC), have gotten parts with swirls of other colors in them, which leads me to believe that they don't hand clean them between runs.

(...) I think they do a little bit of post molding finishing. I'm pretty sure I read about this in one of the books. Depending on the cost to do this (which almost certainly changes over time), they may finish some parts and not others. (24 years ago, 6-Jul-00, to lugnet.lego.direct, lugnet.general)

(...) I disagree. Consider the example of mold tooling that was built to the same form factor for the same machine.
