PROCESS OVERVIEW

Pultrusion

The pultrusion process produces products with extremely high fiber content that are used in a wide variety of industrial, consumer and infrastructure applications. This continuous process incorporates a variety of fibers including glass, carbon, or aramid and other reinforcements including knitted fabrics, continuous filament glass mat, and veils for improved surface finish. Multiple resin systems can also be used depending on the end-use requirements. Fiber is pulled from creels into a catalyzed resin bath and into a heated metal dye that shapes and cures the part. The cured profile is pulled into the machine cutting area where sections are cut and stacked for further processing or finishing.
