Competitive Global Forging Company

Main Items

Main I tems

Ring Rolled Products High tangential strength and ductility make forged rings well-suited for torque- and pressure-resistant components, such as gears, engine bearings for aircraft, wheel bearings, couplings, rotor spacers, sealed discs and cases, flanges, pressure vessels and valve bodies.

Main I tems

Ring Rolled Products

Main I tems

Open Die ForgingsCalled open-die because the metal is not confined laterally by impression

dies during forging, this process progressively works the starting stock into

the desired shape, most commonly between flat-faced dies.

In practice, open-die forging comprises many process variations, permitting

an extremely broad range of shapes and sizes to be produced.

Open Die Forgings

Main I tems

Main I tems

Hollow Bar TypesThe range includes Hollow Bars and Mandrel Bars. Forged hollow bar are suited to applications where high surface pressures exist and friction is to be resisted as in the case of severely loaded gears, axles and pinions. It is used extensively in most industry sectors for applications requiring higher tensile strength.
