| Abstract: | The technology of warm extrusion is numerically simulated in MSC Superform software. The metal flow situation and equivalent strain in different model are analyzed, and the stress under different technics is compared. Considering metal flow situation, and mold strength and its life-span, the result show that it is better to select one step. It has good guiding significance to practical producing. |
