Rocket Motor Case Manufacturing

Cold flow forming of high-strength steel and aluminum preforms over a mandrel, orienting the material grain flow in the axial direction to maximize yield, tensile, and fatigue strength.

Optimized variable-wall profiles that retain additional material in critical stress regions—including forward-dome interfaces, nozzle-skirt interfaces, and fin mounting locations—while minimizing weight throughout the central body section.

Micron-precision machining of front and rear dome threads, locking features, O-ring sealing grooves, and locating-pin bores on multi-axis CNC machines following the forming process.

Precipitation hardening/aging of maraging steels and quenching, tempering, and stress-relieving processes for alloy steels to achieve high toughness, microstructural stability, and minimum thermal distortion.
