The prompt
Design a heavy-duty custom ring spanner specifically for removing and installing an injection molding machine nozzle. The nozzle has a hexagonal wrenching section with a nominal Width Across Flats, SW, of 65 mm. The axial length of the hexagonal wrenching section available for tool engagement is approximately 25mm. The design must be based on recognized engineering standards and real industrial wrench dimensions rather than arbitrary or estimated dimensions. First, research the applicable standards for ring spanners, with DIN 7444 as the primary reference for heavy-duty ring spanners. Also compare real commercially available 65 mm ring spanners from reputable manufacturers such as Gedore, Unior, Bahco, Stahlwille, EGAMaster, or equivalent manufacturers. Use the actual manufacturer dimensions as a benchmark, but do not simply copy a standard wrench. The final design must be optimized specifically for an injection molding machine nozzle.
