Detailed Description
Our custom metal tube bending parts are manufactured for frames, handles, guards, supports and structural assemblies requiring smooth and repeatable tubular geometry. CNC tube bending allows round, square and rectangular tubes to be formed into controlled radii and angles while maintaining dimensional consistency throughout the finished component.
Depending on tube diameter, wall thickness and bend radius, mandrel bending can be used to reduce flattening and deformation around tighter bends. Hole drilling, punching, cutting, welding, end forming and surface finishing can also be integrated to create ready-to-assemble tubular components according to customer 2D or 3D drawings.
Available Surface Finishes
- Powder Coating: Durable protective surface available in customized colors for steel tube components.
- Anodizing: Corrosion-resistant surface treatment for aluminum tubes.
- Polishing: Smooth decorative surface commonly used for stainless steel components.
- Zinc Plating: Cost-effective corrosion protection for carbon steel tubular parts.
Structural & Functional Breakdown
- Continuous Curved Tube Structure: CNC-controlled bending creates smooth continuous contours without multiple welded joints.
- Controlled Bend Radius Structure: Typical 1.5D–3D bend radius range supports both compact and gradual curved designs.
- Integrated Mounting Hole Structure: Drilled or punched holes can be added at specified positions for component installation.
- Multi-bend Tubular Structure: Multiple bends can be formed within one tube to create frames, supports and handles with reduced assembly requirements.
Key Machining Highlights
- Precision CNC Tube Bending: Typical ±1° bend angle control supports repeatable structural geometry.
- Mandrel-supported Bending: Helps reduce wrinkling, flattening and excessive ovality in demanding bends.
- Integrated Secondary Processing: Tube cutting, drilling, punching, welding and end forming can be combined in one production workflow.
- Custom Tube Geometry: Supports customized diameter, wall thickness, bend radius, straight length and hole position according to drawings.
