Bending Techniques Explained
Rotary Draw Bending
- Provides high precision and repeatability
- Ideal for CNC production
- Maintains consistent centerline radius and bend angle
- ShincoFab’s primary method for accurate, mid- to high-volume parts
Mandrel Tube Bending
- Mandrel inserted inside the tube for support
- Excellent for tight radii and thin walls
- Minimizes ovality and wrinkling
- Choose this for CLR near 1×D or strict ovality control
Roll Bending
- Three-roller process for smooth, large-radius curves
- Suitable for sweeping arcs, architectural components, and long radii
- Best when draw-bend tooling isn’t practical
Compression Bending
- Fast, economical method
- Works well for simpler bends up to ~120°
- Slight ovality acceptable
- Useful for reducing cost in basic geometries

Design Your Tube Part for Success
Smart design makes bending easier, cleaner, and more predictable. At ShincoFab, we help you choose the right radii, spacing, materials, and geometry so your parts meet spec the first time. Have questions? Schedule a Design Consultation and get a free DFM review from our engineering team.
01.
Recommended Bend Radii (CLR) vs. OD
- Aim for 2×–4× OD centerline radius for most rotary draw bending.
- Use mandrel bending when CLR is under 2× OD or when walls are thin.
- Choose roll bending for large sweeping radii (7× OD or more).
- Very tight bends (~1×D) add cost and risk—consult ShincoFab before finalizing designs.
02.
Smart Spacing Between Bends and Tube Ends
- Maintain 2×–3× OD of straight tangent between bends for proper clamping.
- Keep at least 2× OD straight from the tube end to the first or last bend.
- Avoid cutouts near bend zones—place holes/slots ≥2× OD from any tangent point.
- Unsure about clearance? ShincoFab can simulate your layout and suggest improvements.
03.
Understand Your Material Behavior
- Stainless steel has higher springback; aluminum bends softer; carbon steel is versatile; copper bends easily.
- Softer or annealed tempers reduce cracking, wrinkling, and force requirements.
- Thin walls + large ODs need tighter process control and often a mandrel + wiper setup.
- Seamless/DOM bends cleaner than welded—if welded, specify weld seam orientation for best results.
04.
How to Reduce Wrinkles and Ovality
- Use proper tooling: mandrel + wiper for tight CLR or thin-wall tubes.
- Increasing wall thickness or radius reduces ovality (flattening).
- Align weld seams with the neutral axis to minimize distortion.
- ShincoFab tunes mandrel size, lubrication, and clamp/pressure die forces to keep bends smooth.
05.
Plan for Tolerances and Repeatability
Typical manufacturing targets:
- Bend angle: ±1°
- Rotation (clocking): ±2°
- Linear dimensions: ±0.010″–0.030″
- Use one consistent CLR across the part to improve repeatability and reduce tooling cost.
- Multi-plane parts need clear rotation data—ShincoFab verifies accuracy using CMM.
06.
Designing Cut Features and End Forming
- Default assumption: normal-to-surface cuts—note any “normal-to-edge” geometry if required.
- Leave 1–2× OD of straight length for end forming such as beading, flaring, or swaging.
- Pre-painted or polished tubes can be bent—ShincoFab applies scratch-reduction measures.
- Need both bending and laser tube cutting? We handle cut → bend workflows under one roof.
07.
Send the Right Data for Fast, Accurate Quotes
- Include OD, wall, CLR, bend angles, rotations, spacing, and material spec.
- Share LRA data, XYZ data, or a STEP file—we’ll validate manufacturability.
- Provide tolerances, quantity ranges, and finish requirements to lock pricing.
- Unsure about the design? Book a free DFM review—ShincoFab will suggest cost-saving improvements before tooling.
Why Choose Our Tube Bending Services
Why you should choose us for your project. At ShincoFab, our tube bending services are built for precision, speed, and value. We make it easy to get parts that fit right the first time. Have a question or need a quote? Contact us now and we’ll help you get started.
01.
Precision You Can Trust
You need bends that are right the first time. We use CNC tube bending with rotary draw and mandrel tube bending to hold tight tolerances on angles, rotation, and lengths. That means smooth bends, accurate centerline radius (CLR), and minimal ovality, even on thin-wall tubes and tight radii. We run 2D and 3D bends, check parts with LRA and XYZ measurement, and use digital inspection so your parts match your model.
If your print pushes limits, we’ll advise when a wiper die, different tooling, or a radius change can prevent wrinkles or flattening. With ShincoFab, you get consistent, repeatable quality across stainless steel, aluminum, carbon/alloy steel, copper, and DOM.
02.
Fast Quotes, Fast Parts
Time matters. We streamline quoting and DFM so you get clear pricing and feedback fast. Upload your 3D model or drawing and we’ll flag manufacturability issues early—like bend tangents that are too close, CLRs that risk collapse, or cutouts inside bend zones. We tune bend programs to reduce springback and scrap, then move right into production.
Whether you need one prototype or a full batch, ShincoFab keeps lead times short without cutting corners. If your schedule shifts, we’ll adjust with you. Need a rush? Tell us your deadline and we’ll map a plan.
03.
One Shop for Cutting, Bending, and Build-Out
Skip the hassle of multiple suppliers. We combine CNC tube bending with laser tube cutting, end forming (beading, flaring, swaging), coping/notching, drilling, and welding for complete tubular assemblies. Need coiling, roll bending for large sweeps, or kitting for easy install? We’ve got you. We also handle fixtures, light machining, and finishing like powder coating—so parts arrive ready to use.
When cut features sit near bends, we coordinate the process to protect edges and keep holes round. With ShincoFab, you reduce handoffs, save time, and lower risk. One PO, one timeline, one team.
04.
Design Help That Saves You Time and Money
Great parts start with smart design. We help you choose the right CLR-to-OD ratio, wall thickness, and material so bends stay clean and strong. If a 1D radius spikes cost, we’ll suggest a 2D option that meets performance and budget. We plan straight lengths for clamping, set bend sequences to avoid collision, and recommend where to place holes and slots away from bend zones.
For tight radii on thin walls, ShincoFab sizes mandrels and wiper dies to prevent wrinkles. For large curves, we switch to roll bending. You get practical, down-to-earth guidance that cuts tooling cost and speeds production.
05.
Quality You Can See, Reliability You Can Count On
You need proof. We provide first-article inspections, digital bend data, and part-to-model reports on request. Our process controls track materials, bends, and measurements through every step. ShincoFab builds for demanding industries like aerospace, automotive, construction, and robotics, where tolerances and repeatability matter.
We document specs, pack kits by station, and deliver on time. If a part must meet strict tolerance or surface rules, we plan dies and protective measures to keep finishes clean. You’ll get parts that fit, perform, and last.
06.
Flexible Volumes, Materials, and Radii
From one-offs to high-volume runs, we scale to fit your needs. We bend stainless steel, aluminum, mild and alloy steel, copper, brass, and DOM—round, square, rectangular, and oval. We handle tight CLR bends with mandrel support and large sweep curves with roll bending. Need laser-cut features, fish-mouths, or tube ends formed to fit?
We do that in the same workflow. If you’re unsure how material temper affects springback or ovality, we’ll guide you. ShincoFab adapts to your specs and budget, then keeps the schedule tight.
