Behavior of asymmetric deformation of rod in locally-lateral upsetting

In multi-stage closed die forging, an optimum shape of a preform is required to economically manufacture more complicate and precise products. This preform promotes to distribute an appropriate volume, and it helps to reduce material loss and forging load at the final stage for the final products. H...
