Powder metallurgy (PM) is an efficient, cost effective technology for making, for instance, gears for automotive transmissions. The technology allows for complex geometries to be produced with few process steps, and design features that are difficult and expensive to produce with traditional machining can easily be incorporated. As a step in demonstrating the possibilities with the powder technology a manual six speed transmission has been reengineered, prototyped and put into a demonstrator vehicle. The gearbox platform is called a M32 and found in for instance Opel Insignia or Saab 9-5. This paper describes the process of developing the demonstrator from the design phase to implementation in a car and summarizes the key findings from the project and technical benefits with PM gear technology.
