The cast structure is to be converted into a forged structure to achieve the required mechanical values. Degree of porosity, gran size and carbide distribution are features of interest for the semi-finished products. The overall forming is done in incremental steps. The capability to process from all sides permits high degrees of forming in one heat and thus quick and cost-efficient forming.

In the continuous ambition to lower further fuel consumption and CO2 emissions, automobile manufacturers are focusing on light-weight structures, higher-strength materials and e-mobility. The GFM radial forging technology, an incremental forming process with mainly 4 radially oscillating tools, offers interesting design possibilities here. The forming of metallic materials can be done in the cold, warm and hot regime. When forging with mandrels complex hollow contours can be produced in a single operation. As the material is formed and not shaped by chip-producing operations a high material utilization and improved material properties are achieved.

Special alloys, super alloys, refractory materials, titanium and many other grades share one thing: they have their own special forming requirements. Many of them can be formed particularly beneficially with our technology.
