Ercolina offers machine models for all shop bending productivity levels from prototype to production with NC or CNC bending controls. With our rotary draw Super and Top bender models you have the ability to accurately control the tube bending process from beginning to end. Ercolina’s machines are used by our customers in many industries and come highly recommended for rotary draw bending applications. Our customers require reliable bending machines that can produce high quality bends, because nothing is more important than bending with accuracy and efficiency.

Ercolina bending dies can be modified to meet most commonly used steel aluminum and stainless tubing materials. The answer is, “Yes.” and with great results. Standard bend tooling can often be modified slightly when necessary to accommodate particular bend requirements or special tube bending tooling can be manufactured to specific requirements of the bending application.Ĭustomers often ask if Ercolina machines and tooling can be used to bend aluminum and stainless tube and pipe. Furthermore, in many cases, Ercolina standard off the shelf stock tooling is offered in many different centerline bend radii to accommodate your bending applications quickly. Ercolina rotary draw benders create aesthetically pleasing bends when the right tooling is matched to the application. Rotary draw benders are the most popular machines for use in bending tube, pipe and solids for applications like: handrails, handrail elbows, and wall returns, handicap handrail, furniture and sign frames, custom vehicle parts such as roll cages, brush bars, nerf bars, light racks, running boards and much more.

This control helps to produce tube bends of superior quality. What distinguishes rotary draw bending from other methods is the line of tangency is fixed at the point of bend to fully control the flow of material. Contact area between the rotating bend die and the counter bend die is referred to as the line of tangency. The counter bend die or pressure die applies opposing force to the tube ensuring high bend quality. Specifically, the forward tangent of the pipe or tube is held in Ercolina’s gripper arm of the bend die as the pipe is drawn around and into the bending die groove. Bends are formed by drawing the material around a rotating bend die center former. Rotary draw bending is the principal method of high-quality tube bending today. Ercolina rotary draw tube and pipe bending machines are ideal for most bending applications.
