What causes flames when part is ejected from Die Cast?
(OP)
I have a large die casting being made. A video shows that when the part is released from the mold, flames shoot out. What would cause this?

A visible flame is nothing more than air or some other gas, heated red hot.

As Ed said, mold lubricant (oil) gets vaporized by the high temperature. When the high temperature vapor contacts air it condenses to small droplets that appear to be smoke. This smoke is very flammable.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
