Abstract

The process comprises a first step wherein by drawing a planar disc a preformed (1) is obtained which has central planar body (3) and a side wall (4) comprised of two cylindrical portions (5, 6) having different diameters and linked by a truncaded portion (7) and a curved reinforcement portion (8) which links the small diameter cylindrical portion (6) with the central body (3). In the second step, said portions (5, 6, 7, 8) are drawn by a conforming device (D) so that a crown (18) is defined whose side walls (19, 21) and bottom part (20) are thicker than the thickness of the central body (3). In a third step, a plurality of evenly distributed channels (16) are formed in the bottom part (20) of the crown. Application to the car industry.
