Abstract

La presente invención se refiere a una varilla de estirado (1) para una unidad de moldeo (15) para fabricar un envase (2) a partir de una preforma (3) y a un proceso para fabricar un envase (2) por moldeo por estirado y soplado. La varilla de estirado (1) se extiende longitudinalmente, de manera paralela a un eje principal Y hetero fásica comprende un cuerpo (4) de forma cilíndrica o tubular, un extremo distal (5) en la prolongación del cuerpo (4), una parte plana (6) situada en el extremo distal (5) de la varilla de estirado (1) y una punta (7) que sobresale de la parte plana (6). La varilla (1) se caracteriza porque comprende un faldón anular (8) en la prolongación del cuerpo (3), a la altura del extremo distal (5), el faldón (8) que tiene una altura (80) inferior a la altura (70) de la punta (7).
