COES tube bending: experience and precision for industrial sectors

COES tube bending is the core of our technical proposal and one of the most demanded services by manufacturers, engineering companies and national and international industrial companies. From our plant in Terrassa (Barcelona), we work with a wide range of materials, diameters and radii, guaranteeing precision, repeatability and impeccable execution in each project.

Cold bending, CNC technology and constant dimensional verification make it possible to obtain complex geometries with tight tolerances, suitable for the automotive, railway, industrial machinery, air conditioning and other high value-added sectors.

Cold bending with uniform results

Cold bending ensures that the tube maintains its mechanical properties and geometrical stability. This process is essential when high surface quality and constant repeatability between series are required.

Materials and diameters with total flexibility

COES works with carbon steel, stainless steel, aluminum and various alloys. This versatility allows us to respond to standard parts, prototypes and special developments according to customer needs.

Tube forming services for custom geometries

Tube forming is a natural extension of bending and allows the tube to be transformed into a fully functional component. Our service includes critical operations for assembly and compatibility with complex industrial assemblies.

Controlled deformation processes

We perform flaring, punching, grooving, diameter enlargement and reduction, among other processes. Each operation is performed with high precision CNC machinery and under repeatability criteria to guarantee consistent results.

Complete integration into production lines

Forming is suitable for long series as well as for medium series or prototypes. It is a key advantage for sectors that require ready-to-assemble parts without the need for further processing.

Pipe welding for complete assemblies

In addition to bending and forming, COES offers welding solutions to supply fully finished tubular assemblies. This allows customers to reduce assembly times and ensure part compatibility from the start of the project.

TIG, MIG and expert manual welding processes

Our team selects the most suitable process according to the material and the requirements of the final application. The results stand out for their resistance, continuity and uniform visual finish.

Technical verification and quality control

Before delivering any welded tubular component, a visual and dimensional inspection is performed. When required by the project, leak tests or other tests requested by the customer are added.

Industrial applications where COES adds value

COES' tube bending, forming and welding capabilities enable us to meet the technical standards of highly demanding industries. Our customers integrate parts in automotive assembly lines, railway systems, agricultural machinery, air conditioning equipment, hydraulics and special metal structures.

Series, pre-series and prototypes

COES is specialized in the manufacture of large series, however, once the project is awarded, we actively participate in it, making the necessary prototypes and pre-series, to validate both the product and the production process.
