Orenco Composites uses a process called filament winding to produce cylindrical-shaped fiberglass parts, such as tanks, scrubbers, basins, and pipes. Filament winding is accomplished by wrapping (winding) continuous fiberglass roving onto a rotating mandrel. The roving is typically “wet-out” through a resin bath just prior to being wound onto the mandrel. The roving is then wrapped in precise — typically helical — patterns. After the roving has been wound on the mandrel to the desired thickness, the resin is allowed to cure, and the part is pulled off of the mandrel. Filament winding is used in many different industries for a wide variety of components, from rocket engine cases to sewer pipes to soy sauce tanks.
