    It is hard to say what the problem is without knowing more of what
    you are trying to do but 1.2 mm thick metal is probably going to
    need a lot more pressure than 6 tons for more than very simple
    doming. Rubber compresses under pressure and urethane doesn't so the
    rubber will not transfer the energy from the press to the metal very
    well where the urethane tends to be much more effective on
    transferring energy. No matter where you buy it urethane is not cheap
    and most suppliers want you to buy a 12" square piece in any
    thickness so even if the cost per square inch is lower the cost per
    piece is much higher.
