CNC Mandrel Tube Bending

Tube bendingE Tube & Wire offers 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 bend tubes having round, rectangle, and square cross sections to the specified tolerances. Custom 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.
