Abstract: A process and system for manufacturing polyurethane products having a continuous section includes placing and fastening multiple injection molds (3) on which is acting, at least, a force in axial direction and, optionally another in radial direction. During the process, the opening is avoided during the polyurethane foaming; injection of the polyurethane in a mold or molds (3), tilted or in vertical on a bench (4) to accumulate CO2 bubbles, at the top part during the polyurethane foaming; waiting for the polyurethane be expanded and withdrawing the mold (3) from the bench (4). The system includes: a feeder (1) of polyurethane; injection system or machine (2) in line, at least, a mold (3) and a bench (4) for placing and fastening the molds (3) located tilted or in vertical.
