Abstract

L'invention concerne un pot moulé à fond composite et un procédé pour sa fabrication. Le pot comprend un corps de pot (1) réalisé en alliage d'aluminium et une tôle composite de fond formée par moulage d'un seul tenant avec la partie de fond du corps de pot (1). La tôle composite de fond combine par laminage une tôle (2) en matériau composite et une tôle (3) en acier inoxydable. La tôle de matériau composite est dotée de plusieurs rainures annulaires (4) dont au moins une paroi latérale est inclinée vers l'intérieur. La tôle (2) en matériau composite est réalisée en aluminium pur, en alliage d'aluminium ou en un autre matériau dont le coefficient de dilatation linéaire est similaire à celui de l'alliage d'aluminium.
