Abstract:
1. Equipment for producing molecularly bioriented tubular profiles, comprising: a mold heated by external heating elements; the mold including asymmetric heads at the ends of the mold, the asymmetric heads configured to allow insertion of a preheated plastic tube inside the hot mold, the preheated plastic tube resting on a lower generatrix of the mold and being disposed asymmetrically with respect to a central longitudinal plane of the mold, wherein the asymmetric heads include fasteners configured to fasten the plastic tube when the tube is inserted into the mold, an inlet for the application of expander fluid and cooling fluid inside the plastic tube , and an outlet for the expander fluid and the cooling fluid, the mold also having a lateral orifice configured to receive lubricating fluid between the mold and the tube to facilitate removal of the shaped tube; wherein the mold is mounted on a support which can tilt and rotate to distribute the temperatures inside the mold during cooling of the plastic tube.
