    Welcome to PF, Navana.
    As far as I know, polyurethane products are generally made by injection moulding. There's a really hefty 'tooling up' expense. I expect that your minimum initial investment would be in excess of $50,000.

    Yep, chances are they're injection moulded. This isn't so much a feature of the material (there are many processes you could use to form other PU products, for instance) but of the form and function of the product, and of the production volumes required.

    Items such as sandals will typically sell in large enough volumes to permit the hard tooling required for injection moulding equipment.

    Thanks you for your thoughtful gesture of giving me this information. Do you have any idea about detailed manufacturing process of PU sandals?

    Thanks indeed for your invaluable reply and could you please figure out the major raw materials comsumed in making PU sandals?

    I don't really know very much about it, and public information is a bit scarce. As much as I don't like to trust Wiki too much, their article might be of the most assistance to you. http://en.wikipedia.org/wiki/Injection_molding.
    There's also this one, http://plastics.turkavkaz.ru/processes/molding/injection-molding/" [Broken], which has a bit of info.
