E Tube & Wire offers CNC mandrel tube bending services for various industries and specializes in components for the food processing industry. Aluminum, copper, and stainless steel tubing up to 3″ in diameter are precision bent at our facility. Our job shop is equipped with an array of manual, CNC, hydraulic, and pneumatic tube benders to handle diverse requirements. We maintain an inventory of mandrels and dies to process tubes at low tooling cost.
We offer CNC tube bending services for tubes with round, rectangle, and square cross sections to the specified tolerances. Custom metal tube benders are used for rectangular or square tubing. Our hydraulic tube benders produce tubular components that comply with stringent Mil-Spec standards. E Tube & Wire also has end-finishing machines to flair, swage, reduce, and expand tube components. Special assembly operations such as bending, assembling, and brazing are also handled.

There are many tube bending methods available, each of which offers unique advantages that make it suitable for different bending projects. Some of the most commonly used are rotary bending, compression bending, and induction bending.
Rotary bending is the primary bending service offered at E Tube & Wire. It involves the use of a fixed die set that is machined to fit the exact outside diameter of the pipe or tube and the insertion of a mandrel to prevent the component from crimping or wrinkling during the bending operation.
Key advantages of this method include:
Compression bending involves bending the material around a stationary die. Compared to other bending methods, it offers faster processing speeds and lower per-unit tooling costs. However, it is not suitable for more complex designs or designs that need mandrels. Additionally, it carries a higher labor cost for low production volumes.
Induction bending involves heating the pipe/tube and forcing it into a bend with a preset radius. As this bending method does not require any special tooling, it is highly cost-effective for small and large production quantities.
Throughout our years in business, we’ve received numerous tube bending questions from customers. Below, we provide answers to some of the most commonly asked questions.
Tube bending is a manufacturing process that creates a bend at one or more places on the tube. The bends can be made to any angle and on any axis. For example, a bent tube can have one 45° bend in the middle or a 30° bend at the top and a 60° bend at the bottom.
Tube winding is a manufacturing process that creates a continuous loop from a tube. Each newly formed coil sits atop the previous one. While the coils are generally circular, they can be made to have a square or other profile. The result is a spring-shaped component.
Both the bend radius and bend diameter are measured in reference to the inside or centerline of the bend. The bend radius is the distance from the inside edge or center of the tube to the center of the bend. The bend diameter is the distance from the inside edge or center of the tube on one side to the inside edge or center of the tube on the other side across the center of the bend. The bend radius is one-half the value of the bend diameter.
