Pull Winding

Pull winding is a process which combines pultrusion with filament winding and is used to produce thin wall, hollow composite profiles which exhibit high strength properties.

Reinforcements, impregnated with activated resin, are wound onto a mandrel, which is then pulled through a heated die. As in conventional filament winding, the reinforcement, which is normally a roving, can be wound in one or more of several directions.

Those resins and reinforcements suitable for filament winding and pultrusion can also be used in pullwinding.
