C*Blade Forging & Manufacturing specialises in the manufacturing of forged blades for thermal / nuclear steam turbines and forged compressor blades for gas turbines, for the power generation market.

C*Blade can produce a wide range of blades in terms of size, weight and finishing grade, from envelope forged blades to those that are ready for assembly. C*Blade is one of the few companies in the world that is able to produce machined blade forgings with overall length up to 1,500mm (59in) and initial weight up to 180kg (400lb).

C*Blade has been working in this field since 1963, always looking for improvement and completion of the manufacturing process. The major equipment for production are three drop-forging hammers with 50,000kgm, 35,000kgm and 12,500kgm of power, and several high-speed CNC milling workstations. The products are manufactured in Maniago (Italy) and sold worldwide with Europe and Asia as the key markets.
