The pultrusion technology is a continuous molding process, that permits to produce a wide range of composite profiles with constant cross-section and with unlimited length.
Unlike extrusion, which pushes the material, pultrusion pulls it out from the heated mold.
Some advantages of this process are certainly the fast and therefore economic production, the possibility to change resins and fibers significantly in order to produce tailored products, and of course the very high structural properties of the final profile.
