Provided are dies having a first section for orienting material being pressed through the die and a second section for shaping the oriented material into a desired form. In an embodiment, the surface area for shaping the oriented material into a desired form is limited. Also provided are polymer articles and processes for making the same. In an embodiment, the processes employ the dies. L'invention concerne des matrices comprenant une première partie destinée à orienter le matériau qui est comprimé dans la matrice, et une seconde partie destinée à mettre en forme le matériau orienté selon une forme désirée. Dans un mode de réalisation, la zone de surface pour mettre en forme le matériau orienté selon une forme désirée est limitée. L'invention concerne également des articles polymères et leurs procédés de production. Dans un autre mode de réalisation, les procédés utilisent les matrices.
