Production hall of wire harnesses in Poland

WeWire We develop and produce customized wire harnesses worldwide

We are a brand of the Coroplast Group and work worldwide on creating innovative solutions for the automobile industry. With approx. 7,100 employees working at 15 production sites, we as a Group are never far away from our customers.

From a built-to-print supplier to a comprehensive solution provider

Both the major automobile manufacturers and their Tier-1 suppliers rely on the broad range of wire harnesses that we provide. At the same time, these well-known customers appreciate our 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 provider of comprehensive development and technical solutions.

We work closely with our customers on innovative and customized wire harnesses concepts. In this way, we actively contribute to the development, on the pulse of time and on an equal footing with our customers. That’s why WeWire’s wire harnesses, which you can now find throughout cars, are more than just the sum of their individual wires. They stand for many years of experience in development and production as well as for continuous improvement. We provide our customers with comprehensive service, including design, development, 3D installation space analysis, prototyping, and series manufacturing at our state-of-the-art production plants.

We are close to our customers

Customer proximity is more than a word for us. We cultivate it on a daily basis. This starts at the beginning of a project and continues through all process steps right up to the finished product. For example, many of our engineers not only attend regular customer meetings, but often work directly with 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.

The highly global industry environment and our demand for customer proximity means that we locate our production, development, and service centers internationally and at different locations on all continents. This results in the international and intercultural composition of the development teams. For example, a team at our production site in Mexico is composed of Germans, Chinese, Poles, and Mexicans – and customer employees from the USA are added.
