I have a Chrysler name tag with a manufactured curve and I would like to straighten it flat. My question is how can I do it without meltening it down to a fishing sinker.

Pot metal (die cast) softens with heat. At c. 175oC it melts suddenly.

 

Clamp it to something, e.g. piece of flat steel, LIGHTLY. Pour boiling water over it and tighten the clamps A LITTLE immediately. Repeat until happy. Wait a day or two and repeat if it is not flat. You may need to use some shims to get it perfect. You can also use a heat gun, but be careful with the temperature.

 

If it is aluminium and not die cast, this does not apply.
