ABSTRACT:
A method of manufacturing an elliptic deep-drawn product including a first step of providing an intermediate product and a second step of providing an end product. In the first step, a rotary forming die is used to form in a blank a substantially round formed portion of a U-shaped cross-section. In the second step, the formed portion is deformed at its semicircular portion by press working to form an elliptic portion, being formed into a final shape.
