【 摘 要 】

The paper considers dependencies of metal forming characteristics on dimensionless geometrical parameters of flat pocket die design at direct extrusion of aluminium thin-walled solid profiles. The theoretical analysis of plastic metal flow is carried out by means of the 2 -D FEM model. The new method for flat pocket die design is proposed in the paper. The die design example is given for non -symmetrical U-shape profile.
