Abstract :� � In the manufacturing processes of rocket parts, especially for the parts that require high strength and�precision as rocket motor case, the processes should be high performance and technology. Materials also�should have unique mechanical properties and corrosion and environments. The parts can be made by�casting, forging, welding, machining, etc. Each process has different advantages and disadvantages�depend on materials and applications. This literature will mention about flow forming process, the modern
process which is not familiar in Thailand. Flow forming is a chipless metal forming technique, high
precision and tolerances, safe time and cost. The deformed microstructures in flow forming are
comparable to the microstructure developed during a typical cold rolling process. The flow formed tubes�achieved excellent geometrical tolerance. This paper also provides the information about the suitability of�flow forming for rocket motor case application.
