Mandrel bending is a highly precise and versatile technique used to bend pipes and tubes without causing them to collapse or deform. This process involves inserting a mandrel—a solid piece of metal—into the tube during bending. The mandrel supports the tube’s interior, ensuring a smooth, uniform bend with minimal distortion, which is crucial for high-performance and aesthetic applications such as automotive exhaust systems, structural components, and industrial piping.
Our advanced mandrel bending capabilities allow for the creation of complex shapes and designs, including tight radii and intricate curves, while maintaining the integrity of the material. Working with both aluminized and stainless steel tubing, we apply advanced processes to deliver high-quality, custom bends that meet exact specifications.
Our mandrel bending services ensure that each bend meets exact specifications, delivering reliable and efficient solutions across a wide range of industries. By applying advanced mandrel bending techniques, we help improve performance, durability, and visual 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:
All Mandrel Bends
Our mandrel bending capabilities support all types of bends, ensuring precise and consistent results. The process involves inserting a mandrel into the tube during bending to prevent collapse and maintain a smooth interior finish. This technique is essential for producing complex, high-performance components.
Aluminized or 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 longevity. These material options ensure durability and performance across a wide range of applications.
Round Tubing from 1″ through 6″
Our capabilities include round tubing with diameters ranging from 1 inch to 6 inches. This range allows manufacturers to meet a variety of system requirements, from smaller high-performance applications to larger heavy-duty configurations, while maintaining precision and performance.
Custom Shapes and Designs: Headers, Flares, Bungs
In addition to standard bends, we support the production of custom shapes and components, including headers, flares, and bungs. These specialized parts are essential for optimized flow and performance in demanding applications. Our expertise allows us to deliver tailored solutions that meet specific project requirements.
Advanced Equipment: 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 in our mandrel bending processes. With accuracy down to 1/1000th of an inch, each bend is verified to meet strict specifications, supporting consistent performance and reliability.
State-of-the-Art Welding: Orbital, Robotic TIG, MIG
Our welding capabilities include advanced techniques such as orbital, robotic TIG, and MIG welding. These methods produce strong, consistent welds that enhance durability and performance, helping manufacturers meet demanding industry standards.
