Mandrel bending is a highly accurate and flexible method used to shape pipes and tubes without causing collapse or distortion. This technique involves inserting a solid mandrel—a metal insert—into the tube during the bending process. The mandrel reinforces the interior of the tube, ensuring smooth, even bends with minimal distortion, which is essential for high-performance and visually critical applications such as automotive exhaust systems, structural components, and industrial piping.
Our mandrel bending capabilities enable the creation of complex shapes and designs, including tight radii and intricate curves, while preserving material integrity. Working with both aluminized and stainless steel tubing, we apply advanced processes to produce high-quality, custom bends that meet exact specifications.
Our mandrel bending services ensure each bend meets precise specifications, delivering dependable and efficient solutions across a wide range of industries. By applying advanced mandrel bending techniques, we help improve performance, increase durability, and enhance overall quality to meet diverse manufacturing requirements.
Mandrel Bending Capabilities
Our mandrel bending services deliver precision and customization to support a wide range of manufacturing needs. Key features include:
Comprehensive Mandrel Bending Services
Our mandrel bending services support all types of bends, ensuring high precision and consistent results. The process involves placing a mandrel inside the tube during bending to prevent collapse and maintain a smooth internal finish. This technique is essential for fabricating complex, high-performance components.
Aluminized and Stainless Steel Tubing
We support mandrel bending using both aluminized and stainless steel tubing. Aluminized steel provides excellent corrosion resistance, while stainless steel offers superior strength and long-lasting durability. These material options ensure reliable performance across a variety of applications.
Round Tubing from 1″ to 6″
We support mandrel bending for round tubing with diameters ranging from 1 inch to 6 inches. This range allows manufacturers to meet a variety of system requirements, from compact, high-performance designs to larger, heavy-duty applications, while maintaining structural integrity and performance.
Custom Fabrication: Headers, Flares, and Bungs
In addition to standard mandrel bends, we support the production of custom shapes and components such as headers, flares, and bungs. These specialized parts are essential for optimizing flow and performance in demanding applications. Our expertise allows us to deliver tailored solutions that meet specific project requirements.
Precision Technology: Faro Arm Inspections with 1/1000th Inch Accuracy
We utilize advanced inspection technology such as Faro Arm systems to ensure the highest level of precision. With accuracy down to 1/1000th of an inch, each bend is verified to meet exact specifications, ensuring consistent performance and reliability.
Advanced Welding Techniques: Orbital, Robotic TIG, and MIG
Our welding capabilities include advanced techniques such as orbital, robotic TIG, and MIG welding. These methods deliver strong, consistent welds that enhance durability and performance, helping manufacturers meet demanding industry standards.
