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.
At Woolf Aircraft Products, Inc., we have been providing tube bending as well as forming and fabrication of bent tube assemblies, for over 70 years. As a leading provider of parts and assemblies for the aviation, military, and transportation industries, we have developed services that add value to the manufacturing process.
Fabrication abilities include tube bending, end forming, boring, grinding, brazing, and welding of a variety of materials. Tube ends can be flared, flattened, swaged, beaded, or formed with a Victaulic groove. Properly forming the ends of the tube is an essential part to ensuring optimal performance of the assembly. We are capable of fabricating assemblies from a variety of standard metals including steel, stainless steel, aluminum, and brass, as well as more exotic alloys including 21-6-9, inconel, and titanium.
A fully equipped tooling department ensures that the proper fixturing and tooling is available to produce the precision parts that customers require. Inspection and testing capabilities include CMM equipment, a laser micrometer and leak testing equipment to ensure all assemblies meet applicable AMS, Mil-Spec, and ASTM industry standards. If additional finishing and fabrication work is needed, trusted outside sources can be contracted, further simplifying customers' supply chain. For more information about our forming and fabrication capability, see the table below, or contact us directly.
In developing welding and brazing services for the aerospace, military, and defense industries, at Woolf Aircraft Products, Inc., we put a focus on precision and versatility.
We offer a wide variety of welding services including: gas tungsten, gas metal, shielded metal, and plasma arc welding, as well as resistance spot welding. Torch brazing is performed in-house while both standard and vacuum brazing are available through an outside partner. For high-volume weldments, 6-axis robotic MIG welding and 2-axis robotic TIG welding are available. Automating the welding process greatly increases efficiency in high volume applications. In-house fixturing ensures precision welds that are very consistent between parts.
Specialized welding capabilities include autogenous orbital welding and wire fed orbital welding for the fabrication of high quality tube weldments. While orbital welding provides very clean and precise welds with high mechanical strength, improperly prepared tube ends can cause premature failure of the weld. We have the proper equipment to trim and face tube ends in preparation for welding.
Although an ideal metal in terms of weight to strength ratio, titanium is notoriously difficult to weld. Purge chambers can be used to weld titanium tubing and assemblies. The use of a purge chamber ensures that the entire surface is blanketed with inert gas, preventing any contamination from the atmosphere that could damage the integrity of the weld. Oxygen sensors are used to ensure that the welding surface is properly shielded throughout the welding process.
Various non-destructive testing and inspection can be performed in-house and by third party certified weld inspectors, according to applicable industry standards. Hydrostatic testing up to 10,000 lbs. can also be performed. For more information about our welding and brazing capabilities, see the table below, or contact us directly.
Our experienced toolmakers and machinists at Woolf Aircraft Products, Inc. are capable of making precision dies and fixtures that produce parts and assemblies to exact customer specifications. The tooling department produces multiple varieties of bending, assembly, and inspection fixtures as well as forming dies. With an inventory of hundreds of bend radius dies, custom shaped tubes can often be bent with no custom tooling required. By combining our extensive list of standard tooling with custom clamps and assembly fixtures, customers receive parts to their exact specifications with a minimal tooling investment.
We specialize in the design and fabrication of custom clamps used to produce close tangent bends in tubing. The ability to produce close tangent bends allows us to fabricate intricate geometries for a variety of different assemblies from engine components to intake manifolds. Tooling is produced on CNC machining centers and verified using advanced CMM equipment to ensure all dimensions and tolerances required to produce a precision part are met.
To economically produce low to medium volume weldments, a modular fixturing table is utilized. Using a modular set-up allows us to produce a range of parts without creating expensive dedicated tooling for each individual part. For higher volume weldments, dedicated tooling ensures precision and repeatability throughout the life of the part. Regardless of volume, our tooling department can create a custom solution for any application. For more information about our custom tooling capability, see the table below, or contact us directly.
