Pultrusion is a proven manufacturing process that produces continuous lengths of reinforced polymer structural shapes with great efficiency and precision. Simply put, a pultrusion machine pulls a raw material (containing any of a variety of resin types such as epoxy, urethane, polyester, vinyl; and fillers and additives) and reinforcing fibers together through a resin impregnation system, and then through a heated steel die which ‘cures’ the material into what is now a rigid and very strong Fiber Reinforced Polymer (FRP) composite that conforms to the shape of the die. The FRP composite continuously exits the pultrusion die and is cut to the required profile length in a final cut-off operation. Secondary operations are then applied to produce the finished product.
