Rocket Shells

Himalaya's plate rolling solutions have been consistently used in rocket shell manufacturing since many years.

Industry Value Chain

In recent years, there has been tremendous focus on launching artificial satellites, human spaceflight, and space exploration. At the same time, there has never been more demand of long-range missiles and other weaponry than now. These are two of the most common usages of rockets.


The structural system of a rocket includes the cylindrical body, the fairings, and any control fins. The function of the structural system is to provide a form of load-bearing frame to transmit the loads from the forces generated during the flight, to serve as an aerodynamic profile to provide low drag for flight through the atmosphere while simultaneously serving as a container for propellant and payload . 

Rocket Shells

Rocket structures need to withstand an average vertical velocity of approx 10KM/sec and an exhaust velocity of up to 3500 m/s and extreme high temperatures resulting due to burning of fuel.

Along with that there is also a need to maximize the mass ratio of the rocket. Hence the rocket designers are in constant need to design high-precision structures of the rockets that minimize the structural mass necessary to safely contain the fuel and propel the rocket in space.

Himalaya Machinery Pvt. Ltd.'s plate rolling solutions have been consistently used in rocket shell manufacturing since many years. Through 40+ years of experience and expertise of building plate rolling machines, we have developed solutions particularly targeted towards the manufacturing of safe, precise rocket shells.

Why Himalaya?

  • Himalaya plate bending machines assure high productivity and extreme precision which is critical for rocket shell manufacturing. Our machines are built to deliver quality rolling and pre-bending of the plates.


  • Himalaya machines have a robust steel structure made from heavy metal plates, connected to each other by a strong box design chassis with interlocking frames & strengthening ribs. These allow for parallelism of all axes and precise surfaces, as well as longevity and precision.


  • We design the rolls with optimal diameter and use forged carbon steel rolls machined by high precision CNC lathes. Our rolls have a special spline-based design that is extremely efficient in connecting the rolls with the planetary gear system. Our rolls are also crowned to compensate for roll deflection during the bending process.

  • Our machines are equipped with a hydraulic system which can work at less than full capacity when jobs less than maximum thickness are rolled. Twin speed operation also reduces the energy consumption up to 50% at slower speeds.


  • Himalaya Planetary driving system used in our machines is efficient and eliminates energy wastage associated with heavy-transmission systems and yet achieves the goal of speed reduction by increasing the stages in gears and pinions.


  • The simple yet robust design of our machines also enables ease of operations and faster manufacturing. And our full package of accessories provides quick movement of rolled plates for rolling, welding, and subsequent manufacturing activities. The high construction quality of our machines means that they can work 24 hours a day and are highly reliable with minimum downtime.
