| Manual Lever Bender | A hand lever rotates a forming die around the fixed tube while a clamp holds the tube in position. | Approximately 6–22 mm outside diameter for common hand tools | Usually about 2–4 times the tube outside diameter | Manual | Maintenance work, plumbing, refrigeration, light fabrication and on-site repairs | Low purchase cost, portable, simple setup and no electrical supply required | Limited production speed, operator-dependent accuracy and restricted tube capacity |
| Compression Bender | A pressure die pushes the tube against a stationary bend former, producing the bend without drawing the tube around the die. | Approximately 6–50 mm outside diameter, depending on machine size | Commonly 2–4 times the tube outside diameter | Manual, hydraulic or semi-automatic | Furniture frames, handrails, simple brackets and repeated single-plane bends | Fast cycle times, straightforward tooling and relatively simple operation | Less suitable for very tight radii, complex shapes or highly thin-walled tubes |
| Rotary Draw Bender | The tube is clamped and drawn around a rotating bend die while a pressure die guides the tube and controls material flow. | Approximately 6–168 mm outside diameter, depending on machine configuration | Often about 1–3 times the tube outside diameter with suitable tooling | Manual, hydraulic, electric or CNC | Automotive parts, exhaust systems, structural frames, fluid lines and general industrial fabrication | Accurate angles, good repeatability, tight radii and attractive surface quality | Requires dedicated tooling and careful setup for each tube diameter and radius |
| Mandrel Tube Bender | A mandrel supports the inside of the tube during rotary draw bending, reducing collapse, wrinkling and flattening. | Approximately 12–120 mm outside diameter for common industrial systems | Commonly about 1–2 times the tube outside diameter, depending on material and tooling | Semi-automatic or CNC | Thin-wall stainless steel, aluminum, copper and precision vehicle or aerospace tubing | Excellent cross-section control and high-quality tight-radius bends | Higher tooling cost, more setup parameters and regular lubrication or mandrel adjustment |
| CNC Multi-Axis Tube Bender | Computer-controlled axes coordinate bending, rotation and feeding to produce multiple bends from a programmed tube layout. | Approximately 6–220 mm outside diameter, depending on axis configuration | Typically 1–3 times the tube outside diameter with suitable tooling | High; programmable and production-oriented | High-volume automotive, HVAC, furniture, energy equipment and complex three-dimensional assemblies | Repeatable geometry, reduced manual labor, quick program recall and efficient multi-bend production | Higher investment, operator training requirements and greater maintenance complexity |
| Three-Roll Tube Bender | Three adjustable rolls apply progressive pressure as the tube passes through them, creating a large-radius curve or coil. | Approximately 20–200 mm outside diameter for common production machines | Large radii, often above 5 times the tube outside diameter | Manual, hydraulic or CNC | Arches, rings, circular frames, heat-exchanger sections and large structural curves | Suitable for long continuous curves and large workpieces with low tooling complexity | Not designed for sharp bends, short straight sections or precise multi-angle tube layouts |
| Hydraulic Tube Bender | A hydraulic cylinder supplies high forming force to push or draw the tube around a die, often with mechanical stops or programmable controls. | Approximately 25–325 mm outside diameter, depending on machine design | Usually about 2–5 times the tube outside diameter | Semi-automatic or automatic | Heavy-wall steel tubing, construction equipment, boilers, structural work and large pipe fabrication | High forming force, robust construction and suitability for large or heavy tubes | Larger footprint, hydraulic maintenance and generally lower precision than advanced CNC rotary draw systems |
| Induction Tube Bender | An induction coil locally heats a narrow section of the tube, allowing controlled bending with reduced forming force and limited tooling contact. | Approximately 50–1,000 mm outside diameter for industrial equipment | Commonly about 2–5 times the tube outside diameter | Automatic or CNC | Large-diameter pipelines, power-generation components, shipbuilding and heavy structural tubing | Handles large, thick-wall tubes and can reduce wrinkling during tight-radius forming | High equipment cost, energy consumption, heat-affected areas and more demanding process control |
