The platform has an outer edge (14) which is thicker than the platform base (12). The side wall (16) of the outer edge facing toward the blade axis is angled. A hook base (8) is molded over the platform on the end region of the blade. An Independent claim is also included for a casting system for producing the above turbine blade.
