Analysis thread on fire:
One person on twitter says his father works with similar machines. Seems to think it'll likely be back up and running by end of night.
"My dad works in metallurgy and has worked with press machines similar to this before. 'Looks like steam or water vapor. Anything of substance would be black smoke. Could be hydraulic hose leaked on something hot. Nothing serious. Better safe than sorry.' "
"Considering black smoke at beginning, definitely metal on metal overheating leading to black smoke. Could’ve been a number of things, most commonly a failed cooling or press got caught and wasn’t able to abort prior to cast overheating."
Says they used sand to put out the fires because they likely didn't have the foam on hand which caused all the smoldering.
