Tube Bending

Our inventory of bend tooling and equipment at Woolf Aircraft Products, Inc. is among the largest in the country. We bend a variety of steel, stainless steel, aluminum, and alloy tubes from 0.0625" to 7" in outer diameter. Depending on material, size, volume, and bend radius, precision rotary draw bending or roll bending equipment is used. In rotary draw bending, a mandrel is used to support the inner structure of the tube during the bending process to prevent distortion. In roll bending, the length of tubing is passed through a series of rollers to form the desired radius.

The variety of equipment available on the shop floor allows us to manufacture components and assemblies in a range of production volumes. CNC bending equipment can accommodate multiple radii for extremely efficient bending of high-volume orders. We specialize in the precision bending of thin wall tubing, tight radii and close tangent bends. In-house fixturing and specialized clamps provide the ability to perform multiple bends in close proximity to one another, allowing us to create a myriad of geometries.

Many forming and fabrications services are available to complement our tube bending capabilities. These services include a variety of end forming capabilities, drilling, machining, brazing, and welding. All work is done to applicable industries standards including Mil-Spec, AMS, ASTM, and ASME requirements, as specified. Our quality management system is ISO 9001:2008C and AS9100C certified. In addition to in-house services, a variety of outside services can be arranged as needed. Outside services are performed by partner facilities that carry the necessary government, Nadcap, and other certifications required by the industries we serve. For more information about our tube bending capability, see the table below, or contact us directly.
