Abstract: The present invention relates to a method for producing a blow-molded tubular body having multiple dimensions with the following stages:a) extrusion of a tubular component that is closed at the front, with injection of gas inside the tubular component (10), and engagement of the tubular component with a shaping unit (12, 13),b) deposition of the shaped tubular component, in the plastic state, on a high-level half-mold part (15),c) free descent of a part of the tubular component onto a low-level half-mold part (18), located at a level that is lower than that of the high-level half-mold part (15),d) closure of the half-mold and blow-molding.
