Heating thin aluminum or copper foil

Can we heat think aluminum or copper film at web speeds of 30 fpm?

The short answer is Yes. The long answer is that the process needs to be defined, designed and implemented correctly. A typical thin foil of aluminum can be heated with induction with a pancake style coil, but if the pancake style coil extends beyond the 12 inches wide, then the edges will overheat. If the pancake style coil is within the bounds of the aluminum foil, the edges really become not as hot. You have to design the induction heating process correctly, where we actually use induction flux controllers to allow adjustability. The manufacturing line to create good heat on the aluminum foil as it's moving at your 30 feet per minute speed.
