I think it will be very difficult to get a good outcome with epoxy if the deep draw process involves forming metal.If it involves forming ABS or similar plastics over a machined form there are several epoxy based tooling blocks that may be suitable.You might try Sika,Ren or local alternatives.Many of them are resistant to 120 deg C and I doubt that a thin sheet of material has the thermal mass to transfer a great deal of heat into a block that is a fairly effective insulator.The point of concern is that the filler in such block materials is hard on cutting tools as it is usually mineral based and consequently abrasive.
