Centimeters is a whole different story. You could still have it vacuum formed but not realistic to spin form it. 1mm yes, 1cm not even remotely possible. I'd think that would take a huge stamping press and possibly hot formed. Maybe plasma or Hydro-formed.
I'd look for a scrap tank and cut off the end, IF you can find one 1cm thick.
If you have a boilermaker pressure vessel fab shop in your area, maybe they can offer you something?

If my area have a boilermaker, isn't them fabricate the pressure vessel's cap with metal? But what I want is only a plastic dome, is that they can do it as well? If I vacuum form it, how shall I make my male and female die? Is it by metal casting? Thank for giving me a lot of idea.
