Default Re: Oven or reflector with infrared

I've wondered the same thing. People go to a lot of trouble to make the temps inside ovens uniform, with fans, fancy thermostats, etc. all designed to get the entire part to a certain temp and hold it there for a certain time. Then they offer these IR heaters to coat big items, as if getting the part hot on one side and warm on the other (and on the edges) will be good enough. They might be OK for helping to cure wet paint, but I don't get how they could possibly heat anything big evenly enough for a good cure job without some areas being under cured and some over cured. Maybe someone here has done it, if so, I'd really be impressed. I have never heard of any PC business using them.

Putting an IR curing lamp inside an oven makes no sense to me because ovens need convection heat inside, not IR. The air needs to be heated. Maybe it would work in a half-assed way if the inside of the oven was lined with mirrors.
