Our core competencies

As a specialist in advanced engineering and continuous improvement, we are the market leader for specialized products that are continuously developed. We are helping to shape current developments such as e-mobility, autonomous driving and in-vehicle connectivity.

  • We are a full-service provider – for all types of wire harnesses in the automotive sector and other fields of mobility.
  • We are a system supplier and automation specialist in the areas of wheel arch wiring, injection-molded components, and special wire harnesses.
  • We are a leader in the use of automation technology in the production of wheel arch wiring, in-house design of process optimizations, and the development of innovative system technology (robotics, linked transfer lines, software development).
  • We stand for interdisciplinary concept development and implementation – all from a single source (request, installation space analysis, 3D routing, manufacturing of prototypes, pre-series production, optimization up to series maturity, series process development, prototype qualification, series support).
  • We rely on the latest simulation software – to examine and develop dynamically moving wire harness designs.
  • We have a central laboratory and technical centre in Wuppertal for design and product testing, fault analysis on prototype, series and complaint samples, material analysis, the creation of test plans according to customer-specific requirements and current standards.

High standard We work with state-of-the-art equipment, globally standardized processes and, among other things, with these common tools:

  • IPS
  • NSIS Work Bench 
  • Solid Works Plastic
  • CATIA V6 and NX (3D-Design and DMU)
  • EBCable (wiring diagrams)
  • LDorado and AutoCAD (2D applications)
  • All common interfaces to customers

Always close to our customers

Customer proximity is not just a buzzword for us – it is a lived practice from the very beginning. This starts at the beginning of a project and continues through all process steps right up to the finished product. As experts in the cabling of complex installation spaces, we are always close by with our worldwide locations in China, Poland, Tunisia, and Mexico, as well as our service centers in Ingolstadt, Wolfsburg, and Kunshan.

Ali Iliköz, Head of Business Unit WeWire

For example, many of our engineers not only attend regular customer meetings, but often work directly with our international customers as resident engineers in their development departments. We see this not only as a practiced service mentality, but also as an opportunity to help shape development and keep our finger on the pulse of the times.

WeWire production sites worldwide

From a pure contract manufacturer to a comprehensive solution provider

Many well-known automobile manufacturers, such as VW, BMW, Audi and Ford, rely on our wide range of wire harnesses that we provide. At the same time, these customers appreciate our consistent service philosophy and the wealth of problem-solving expertise that WeWire engineers have gained through many years of experience. Over the last two decades, our company has continually grown from being a build-to-print supplier to a development and solution provider.

We work closely with our customers on innovative and customized wire harness concepts from the wheel arch to the rear. This means we actively contribute to the design and development process, keeping pace with the times and working on an equal footing with our customers.
We offer a comprehensive service: from design and development to 3D installation space analysis, prototyping and series manufacturing at our modern production sites.

This is how our wire harnesses are created, which are much more than the sum of their individual components: they represent many years of experience in development and production, as well as continuous improvement.
