Abstract

La invención se refiere a un método para dar forma o conformar productos fabricados de HDPE o PA, particularmente una conformación espacial de tubos de HDPE o PA, en el cual se da forma a o conforma el producto semiterminado de HDPE o PA. Primero se calienta un producto semiterminado de HDPE o PA a temperatura T cerca de la temperatura de fusión Tg del material, de modo que el material permanezca en estado sólido, el producto semiterminado fabricado con HDPE o PA se deja a esta temperatura durante un periodo de tiempo t1 requerido para obtener la plasticidad y para romper total o parcialmente la estructura cristalina o semicristalina del material de HDPE o PA y para relajar la tensión interna del material de HDPE o PA y para restaurar el estado amorfo o parcialmente amorfo del material, después de lo cual, el producto semiterminado con HDPE o PA se inserta en un accesorio de conformación y la temperatura del material de HDPE o PA disminuye gradualmente a la temperatura ambiente. La invención también se refiere a un dispositivo para realizar el método.
