The discussion centers around the technology and processes involved in making polyurethane sandals, including manufacturing methods and raw materials. Participants explore the specifics of injection molding as a primary technique and the associated costs and requirements.
Participants generally agree that injection molding is a likely method for producing polyurethane sandals, but there is no consensus on the detailed manufacturing process or the specific raw materials involved.
Some participants express uncertainty about the availability of detailed information and the specifics of the manufacturing process, indicating a reliance on external sources for further details.

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.
brewnog said: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.
