Interstuhl Partners With Drre To Revolutionize Office Chair Production With Cutting-Edge Coatings

Interstuhl, a German-based high-end furniture design company, has been perfecting its craft for over 60 years, producing top-quality office chairs for various industries, including industrial and laboratory applications. The company’s commitment to quality and innovation is evident in its decision to invest in modern coating technology from Dürr to further enhance its production process.

At the heart of this transformation lies Dürr’s robotic mould-surface technology, which enables Interstuhl to automate the coating of foam moulds with unprecedented precision. The EcoSupply2 Core paint supply station, paired with a 2K process controlled by an EcoAUC, forms the backbone of this cutting-edge system. This synergy allows Interstuhl to achieve an efficient coating process with up to five distinct colors.

Interstuhl’s headquarters, located in Meßstetten, Germany, serves as a hub for its industrial and laboratory chair production. The company invested in Dürr’s technology to boost efficiency and quality in the manufacture of Interstuhl’s work chairs. The key to this success lies in the precise application of Dürr’s robotic mould-surface technology.

The EcoGun AS Auto pro spray gun plays a pivotal role in this process, meticulously coating the inner surfaces of foam moulds with a specialized liquid PU foam that absorbs the applied color. This innovative approach not only enhances the appearance of Interstuhl’s chairs but also provides vital conductivity properties. Fabian Schilt, Head of the European Industrial Sales Team at Dürr, emphasizes the significance of this technology in various industrial settings: “The paint used is special – it serves multiple functions. In addition to providing color, it provides the necessary conductivity.”

In September 2025, Dürr collaborated with PU plant specialist Hennecke to support Interstuhl’s expansion into advanced technology. The joint effort involved installing painting equipment on an existing robot at the Interstuhl site in Meßstetten-Tieringen. This system comprised a painting robot equipped with the EcoGun AS AUTO pro spray gun, six EcoSupply2 Core stations for paint supply, and the EcoAUC 2K control unit.

The EcoSupply2 Core paint supply station is an exemplary model of industrial design, boasting a compact footprint and user-friendly interface. Its versatility makes it ideal for various applications where painting occurs in confined spaces. At Interstuhl, this system is complemented by additional components from Dürr’s product portfolio, including pumps from the EcoPump9 series, valves, and paint change blocks.

The technical requirements of Interstuhl’s paint material were a major consideration in the selection of these components. This specialized paint has distinct challenges: it is difficult to flush, hardens quickly, and tends to clog valves. However, Dürr’s products have impressed Interstuhl with their exceptional performance. The company praises the absence of dead space in Dürr valves, which ensures reliable and clean processing.

Andreas Kunst from Interstuhl succinctly captures the essence of this collaboration: “We were convinced by Dürr right from the first demonstrations of the painting technology. The technical team was always there to support us and led the project to success with a great deal of expertise and commitment.”

The seamless integration of Dürr’s technology into Interstuhl’s production process has yielded impressive results. This collaboration serves as a testament to the power of innovation and partnership in driving business growth and enhancing product quality.

Interstuhl continues to push the boundaries of its craft, and its commitment to using cutting-edge technologies will remain a cornerstone of its success. Dürr’s robotic mould-surface technology has undoubtedly played a pivotal role in this journey, providing Interstuhl with the tools needed to meet the demands of an increasingly competitive market.

By embracing modern coating technology, Interstuhl is not only improving its manufacturing efficiency but also elevating the quality of its products. As the company looks toward the future, it is clear that Dürr’s innovative solutions will remain a vital component in its ongoing pursuit of excellence.

The success story of Interstuhl and Dürr serves as a shining example of how strategic partnerships can drive growth and innovation in industries where precision and quality are paramount. By combining their expertise and resources, these two companies have created a truly winning formula for the modern manufacturing landscape.
