Teflon (polytetrafluoroethylene) is 'stuck' to the pan by first sandblasting the pan to create tiny scratches on the surface, then a thin coat of Teflon is sprayed on which flows into the scratches, then it's baked at a very high temperature (can't remember what) which causes the Teflon to harden. Then a sealant is applied and it gets baked again.
p.s. It's nothing to do with the 'space race' - it was invented in 1938 and one of its first uses was in the Manhattan Project.

to get teflon to stick to metals you do a process called powder coating where the metal surface is etched to make it rough and then the teflon is sprayed on to the surface and heated.

Its mixed with a kind of plastic, heated up to a couple of hundred degrees & then blasted onto the saucepan surface. Once it has set, similar temperatures won't re-melt it.

Teflon is only non-stick to certain textures, ofcourse it sticks to some moluecules.

the teflon is electrically plated the pan, so that it won't peel off
