Tube Bending Services
We provide repeatable, tight-tolerance bending for round, square, and rectangular profiles, backed by ISO 9001-aligned quality controls. As an integrated manufacturing partner, we combine tube fabrication with machining, welding, and finishing to simplify your supply chain.
CNC Mandrel Bending
Minimizes wrinkling and ovality on tight CLR; ideal for thin-wall stainless and aluminum.
Engineering Review & DFM
Feedback before production to optimize manufacturability and reduce risk.
One-Stop Fabrication
In-house laser cutting, notching, welding, and finishing for complete assemblies.
Technology & Methods for Tube Bending
We select the right process for your geometry, material, and finish requirements—balancing tight radius control with surface quality and production repeatability.
Mandrel Bending
Ball/plug/wiper mandrels for thin-wall tubes; minimizes wrinkling and ovality at tight CLR. Best for precision cosmetic applications.
Rotary Draw
Most common for precision industrial bends; excellent repeatability for production runs with consistent angles.
Roll Bending
Large radii and long sweeps on thicker sections; ideal for architectural and structural applications.

Pipe vs Tube: What We Bend
Understanding the distinction between tube and pipe sizing ensures accurate tooling selection and inspection alignment.
Tube Specification
Specified by OD × wall thickness (e.g., 25mm OD × 2mm wall). Tube sizing is consistent across different wall thicknesses for a given OD.
Example: 1" OD × 0.065" wall
Pipe Specification
Specified by nominal size + Schedule (e.g., 1" Schedule 40). Schedule determines wall thickness, with ID as the primary dimension.
Example: 1" NPS Schedule 40 (actual OD: 1.315")
For your RFQ: Provide nominal size, Schedule, and seam type (ERW/DOM) for pipe; or OD × wall for tube. We align tooling and inspection procedures to your drawing language and verify dimensions using the appropriate measurement standards.
Materials & Profiles We Bend
We select optimal tooling and process parameters for each material and profile to ensure precise, consistent results—from standard carbon steel frames to cosmetic-grade stainless assemblies.
Common Materials
- Stainless Steel (304/316): Corrosion resistance and cosmetic finish
- Carbon Steel: Structural strength for frames and chassis
- Aluminum (5052/6061): Lightweight applications with good formability
- Brass & Copper: Specialty alloys upon engineering review
Supported Profiles
- Round Tube: Most common; excellent for tight radii
- Square Tube: Face collapse control with dedicated tooling
- Rectangular Tube: Structural applications with orientation control
- Schedule Pipe: Per your drawing specifications for fluid/structural use
Surface Protection & Cosmetic Control
For cosmetic applications, we use soft jaws, protective liners, and wrap strategies to minimize clamp marks. Post-bend finishing options include polishing, brushing, powder coating, and anodizing to meet your aesthetic and functional requirements.
Quality Assurance & Documentation
ISO 9001-certified processes with traceable inspection records ensure dimensional accuracy and repeatability across prototype to production volumes.
ISO 9001 Certified
Documented quality management system with regular internal and external audits.
FAI → In-Process → Final
First Article Inspection followed by in-process checks and final verification with traceable records.
Available Documentation
CoC/CoA, CMM reports (external partner), material certificates, and inspection logs on request.
Inspection Capabilities
Standard metrology includes calipers, micrometers, and angle gauges for dimensional verification. For complex geometries requiring CMM measurement, we partner with certified external metrology labs. Springback compensation and ovality control are verified during FAI and adjusted as needed for production runs.
Applications Across Industries
We build for demanding environments where precision bending, dimensional consistency, and surface quality are critical to function and assembly.
Industrial Automation & Robotics
Machine frames, robotic bases and pedestals, AGV/AMR chassis, conveyor guards. Fixture-friendly bends with consistent repeatability for automated assembly.
Automotive & Powersports
Roll cage elements, exhaust systems, racing chassis components, roof racks. Tight CLR capability with controlled ovality for structural and safety-critical applications.
Marine & Architectural
Polished stainless handrails, yacht hardware, railings, T-tops, radar arches. Cosmetic surface control with protective handling for high-visibility installations.
Thermal & HVAC
Heat exchanger coils, serpentine bends, fluid transfer lines. Pitch control and thin-wall bending for efficient heat transfer applications.
