This forming technology drop forges or presses the warm or cold raw material into two or more multi-part moulds (closed-dies).

When drop forging parts, the structure of the raw material remains intact thereby maintaining excellent mechanical properties. These forged parts have highly elastic properties, are ductile and have dynamic resiliance. Sudden shock overload applied to these parts does not lead to brittle breakage, but they absorb maximum tension by being a bit plastic.This attribute is achieved without any particular constructional effort.
 

The already existing very good mechanical properties can be supplemented and optimized by heat treatment. Parts produced using these methods are well suited for later machining.

By combining processing methods such as warm-cold forming or cold coining, dimensional accuracy can be reached which may make additional machining unnecessary.
