I think you will find the dash is actually a film of a precolored material (vinyl?)that is molded to the shape of the dash, this is placed in a mold face down and a polyurethane foam is injected to the back of it. Some inserts, fasteners etc are molded in place, the foamed assembly is removed from the mold and you have your dash panel. Some trimming of the foam may be required along with adding any nameplates etc.
