In this forming process, raw materials are shaped by cold or hot deformation, typically through hammering or pressing in closed or open dies. An additional forging technique is ring rolling, used to create large, thin-walled rings from smaller starting rings.

In open-die forging – also referred to as manual or free forging – the workpiece is formed by repeated tool impact.
Ring rolling enables the manufacture of profiled rings with high dimensional stability and minimal material waste.
One key advantage of forging is the preservation of the metal’s natural grain structure, which results in components with excellent elasticity, strength, and fatigue resistance. Even under sudden overload, forged parts undergo plastic deformation rather than brittle fracture, effectively reducing stress peaks.
Targeted heat treatments can further enhance mechanical properties, while also improving machinability.
Process combinations, such as hot-cold forming or cold precision stamping, enable achieving tolerances so precise that further machining is often unnecessary.
