Actually, it's not a trivial thing to do! Normally, Teflon would not adhere to the pan well.
What the manufacturers do is first put down a layer of PTFE telomer as a primer layer, and then coat over that.
Huh? what's a telomer?
Well, normally a polymer is a really long molecule and is capped at both ends by say hydrogen, or in this case, fluorine atoms. In the case of the telomer, one end is flurinated while the other has a "special" group on the end that has some affinity for the metal and will bond with it (either covalently or by Van der Waals bonds). In this case, the actual identity of the telomer is a big industry secret, something that DuPont and BASF guard very closely. If I had to guess though, it's probably some type of sulfide or sulfhydyl (-SH) group.
Without the telomer, nonstick cookware wouldn't exist.

because when it's made, intense pressure is put on the layer of teflon at high temperatures. trust me, I heard a speech on it.

Har.
I haven't heard this one since 1972.

Your premise is obviously untrue.
