Tube Bending

Custom CNC Tube Bending Service in China

We provide professional CNC tube bending service for a wide range of metal pipes and profiles, serving global clients in construction, automotive, furniture, HVAC, machinery and other industrial fields. Equipped with advanced CNC bending machines and skilled technicians, we deliver high-precision and repeatable bending solutions for both small-batch prototypes and large-volume mass production.
We own a full set of CNC tube bending molds for round pipe, square tube, flat iron, angle steel, channel steel and special-shaped profiles. Our bending equipment and tooling fully meet the forming requirements of standard arcs, elliptical arcs, S-bends and rotary modeling shapes.
Our bent products are widely applied in building curtain walls, indoor & outdoor decoration, road & bridge projects, auto parts, furniture accessories, bathroom fittings and all arc-forming related products.
Metal tube bending is an essential process in metal tube fabrication. It permanently forms metal tubes, pipes, bars, rods and profiles via bending machines and customized molds into fixed shapes. It is widely used in furniture, HVAC, automotive, mechanical equipment and construction industries.
We offer tube bending for carbon steel, stainless steel, aluminum, brass and copper. Available material shapes include round, square, rectangular, hexagonal and oval profiles.

Precision Tube Bending Processes

We adopt multiple tube bending methods to meet diverse structural, material and precision requirements.

Tube bending techniques are mainly divided into hot tube bending and cold tube bending, each with unique advantages for different applications and material specifications.

Hot Tube Bending

Hot tube bending heats the tubing to high temperature to soften the metal, making bending easier and lowering the risk of cracking or breaking.
The main disadvantage is thermal expansion: metal expands when heated, which may cause dimension and angle deviation after cooling, failing to meet strict specification tolerance.

Cold Tube Bending

Cold tube bending is performed at room temperature without heating the material. It features higher dimensional precision with no thermal deformation, ensuring stable shape and accurate angles. It is the ideal choice for projects with tight tolerance requirements.
Both bending methods are widely used in manufacturing. The selection depends on material type, bend complexity and dimensional accuracy standards.
With years of practical experience in metal tube fabrication, we support all common bending technologies. For more professional process details, you may refer to relevant industry Wiki resources.

Bar and Flat Bending Service

Bar and Flat Bending Service
We specialize in bar bending and flat bar rolling services with rich experience. Bar rolling converts flat bar stock into precisely curved components, a cost-effective alternative to laser cutting and plasma cutting.
Bar rolling greatly reduces material waste by producing flat rings and ring segments efficiently. Compared with blanking from whole sheet metal, it saves raw material, production time and overall cost while maintaining high processing accuracy.
We run a full range of advanced rolling and bending equipment to match the optimal machine and tooling for your project. Our technology effectively controls deformation during bending, enabling high-precision processing of large flat bars. Proper equipment matching minimizes trimming loss and further cuts your production cost.
Our professional bar rolling capabilities include:
  • Easy way: Rolling perpendicular to the bar’s largest dimension
  • Hard way: Rolling parallel to the bar’s largest dimension
All processes are completed with strict dimensional tolerances. We also handle complex multi-bend parts and variable radius bending, delivering stable quality even for urgent delivery schedules. Feel free to contact our team for a custom quote.

RFQ & Production Notes for Bending Service

  1. Material Grade

    Different countries adopt standards like ASTM, API, DIN, BS, JIS, AS and NZ. For cost and procurement reasons, we recommend equivalent Chinese GB standard materials as substitutes. We provide chemical composition and mechanical property data for your reference.

  2. Some special materials require customized production, subject to minimum order quantity.
  3. Bent parts require matched molds and fixtures. Once mold cost is paid, we can provide free samples for your testing.

  4. Material Size Conversion

    Millimeter (mm) is our standard unit. We convert inch and gauge sizes into metric dimensions per your drawings, and confirm outer diameter, inner diameter and wall thickness with you.

  • 1 inch = 2.54cm
  • 1 foot = 12 inch = 30.48cm
  • Gauge to Thickness Chart (keep original table unchanged)
