[QUOTE="Clawcoins, post: 8568010, member: 77814"]As mentioned "floating roofs" are the outcome of Die Polishing, which is a common die maintenance routine to extend the die's usage lifespan. This polishing removes surface imperfections by polishing it out; it also removes fine design details. The thin details of the roof support are polished away, as is a thin layer of the entire surface as it is smoothed out. Having weakness or non-existent FG is common due to the die surface polishing. Die polishing, by it having a smooth surface reduces friction which helps the metal flow and distribute or stretch to fill in the dies cavities. Thus it aids in prolonging tool life and reducing replacements.[/QUOTE]
