Tail rotor drive shafts made of titanium, stainless steel or aluminum are predestined components for flow-forming procedures. The shafts are up to 4 m long, have a wall thickness of 1 – 3 mm and pose high demands to straightness and concentricity. The precise flow-forming procedure permits producing these shafts with a wall thickness tolerance of less than 0.05 mm and a concentricity of inner- to outer diameter of less than 0.03 mm. Different wall thicknesses within a shaft can be implemented easily in material utilization of up to %97.

Cylinders and pistons with an integrated piston rod for landing gears and actuators for doors or other applications are made of stainless steel, such as 15-5 PH. The cold forming process reduces material loss by more than 60% as compared to conventional mechanical processing. Integration of connections and other applications can reduce the number of components at any one cylinder, which saves assembly effort and weight. Weight-optimized cylinder pipes and piston rods with integrated pistons that have a component length of up to 2 m can be produced beneficially by the flow-forming procedure.

Seamless cones, housings and nozzles of niobium, tantalum, titanium, Inconel or other heat-resilient materials are beneficially produced of sheet metal by way of conic flow-forming, referred to as “shear-forming”. Extremely thin wall thicknesses in the area of 0.2-0.5 mm, as well as wall thicknesses of up to 10 mm, can be produced with outstanding
