I need to very quickly learn about making rigid molded polyurethane foam parts and the molds themselves. Does anyone know of a quick seminar or school that I can attend? Any advice is appreciated
You might want to contact a company called "Smooth - On" they are quite the experts in all sorts of casting urethanes, mold making and foams. They have a web site you can look up. They also have books and tapes showing how - to information.
Otherwise there are several other firms who sell urethane and provide detailed help, I suggest you Google Tooling resins, and casting urethanes etc.
