| I ordered 4 stators of 1200 x 240mm and one looks like this. How can I flatten it? |

You could make a frame. It would be very hard to fix that perfectly.
Edit: Sandwich it between two pieces of 3/4" plywood and park you car on it overnight. |

| talk to a pro at an auto body shop. It won't cost to ask. |

Ask someone who works in a machine shop or sheetmetal shop, as they will have the press to bend it back and the flat surface to check it against.
(Just holding it flat won't work: It needs to be taken past the yield point.) |

| You may find that when you assemble it into a sandwich under pressure, the resulting cell is flat. My stators have a noticeable bow unassembled, which straightened out beautifully when I glued the whole shmeer together. |

Great to hear that close enough may be OK. The other three have a slight and simple warp which I suspected would work well enough.
I was thinking of parking my car on it like ak_47_boy suggested. I somehow knew what Tosh says is true, and I hope that by leaving it for a while the thermal cycling may give it what it needs.
I guess since I was planning to use 1/16" spacing and foam double sided tape, and due to my inexperience I was afraid it wouldn't be good enough. |
