Basic Numerical Analysis of a “Samanta” Based Forward Extrusion Process

Cold forging enables industrial mass production of steel based components characterized by high strength and precision. The present study focuses on the FE-based analysis of a forward extrusion process. The investigated process is the so called “Samanta”-process. In practice, this is also refered to extrusion in package. During the forming, multiple blanks are pressed sequentially through a die. The results reveal the process-specific "crown-shaped" area in the upper end region of the components. Furthermore, the tribological conditions reveal a great influence on the resulting component properties.
