Flowforming Case Study 5: Military

Background Information

Application: Flowforming for Defense Applications
Part: Rocket Motor Case
Material Formed: Maraging Steel

Before: Customer Requirements

Military Customer Requirements
  • Made from maraging steel
  • All welds require X-ray and magnetic inspection
  • Hydrotesting to 2300 psi
  • Machining operations require close tolerances on both ends of part

After: PMF Improvements

Military PMF Improvements
  • Flowforming allows for seamless construction, eliminating welds
  • The body is made from a machined preform, making it easier to obtain the required thickness and diameter specified.
  • The final part is machined and holes put in to very tight tolerances.
