Frequently Asked Questions
There is no single figure — the practical minimum is expressed as a multiple of tube diameter, and it depends on wall thickness, material and tooling. Rotary draw bending typically works from around 1.5D upward with a mandrel, while rolling starts at 10D. The articles here explain how the limits are derived.
Because the parts change. Thinner walls, higher-strength alloys, tighter tolerances and shorter lead times all push the process, which is why bending power systems moved from purely hydraulic to servo-electric and hybrid drives over the past three decades.
Automotive and exhaust, fitness and furniture, HVAC and refrigeration, shipbuilding, construction machinery, and power and process pipework. Each sets different priorities — surface finish, wall thinning limits, cycle time or code compliance.
