Today’s modern missiles are capable of incredible targeting precision, thanks to highly sophisticated guidance and flight control systems. In most cases, flight is controlled by pivoting fins attached to the body of the missile such as the canard shown in Figure 1 above. Missile flight is highly sensitive to the exact surface geometry of control surfaces, especially at supersonic speed.

We have written a case study comparing CNC (Computer Numerical Control) machining, MIM (Metal Injection Molding), and Liquidmetal injection molding for missile flight control surfaces.

  • Modern missiles require exact flight control surface geometries
  • CNC (computer numerical control) machining
  • MIM (metal injection molding)
  • Liquidmetal Injection Molding
  • Cost Comparison
  • Scaling Production

This brief case study examines the crucial requirements of supersonic missiles and the cost of an example missile fin (canard) manufactured by CNC, MIM and Liquidmetal Injection molding.
