Is there any way to heat a 200X300X10MM aluminum plate very uniformly to 200-300 degrees in the shortest time. I have tried electric heating tubes or high frequency methods before, and there is a problem of uneven heat. It takes a long time to irradiate with a quartz lamp. It takes time to heat up to 300 degrees.Which is a better infrared tube or other method to achieve the effect?The shorter the heating time, the better.
I think your problem may be caused by reflection on the surface of the aluminum plate.
So I suggest you can think of a way on the surface of the aluminum plate?
Black coating may make the surface uneven. . . . . . .
