Interstuhl Automates Seat Coating with Dürr’s Robotic Mould-Surface Technology

Why It Matters

Automating mould coating cuts cycle times and guarantees ESD‑compliant finishes, giving Interstuhl a competitive edge in high‑spec office furniture markets.

Key Takeaways

• Robotic system coats foam mould interiors automatically
• Conductive paint prevents static in cleanroom chairs
• EcoSupply2 Core saves space in confined production lines
• System supports up to five colours with quick changeover
• No dead‑space valves ensure consistent, clog‑free paint flow

Pulse Analysis

The furniture industry is increasingly turning to robotics to address labor shortages and tighten quality control, and Interstuhl’s partnership with Dürr exemplifies this shift. By deploying a dedicated painting robot equipped with the EcoGun AS Auto pro, the German chair maker can uniformly apply a specialised polyurethane coating inside each foam mould. This eliminates manual spraying, reduces material waste, and ensures each chair meets the stringent aesthetic and functional standards expected by industrial and laboratory users.

At the heart of the solution lies Dürr’s EcoSupply2 Core paint‑supply station and the EcoAUC 2K control unit, which together manage up to five colour formulations in a compact footprint. The coating not only imparts colour but also embeds conductive particles, a critical feature for chairs used in electro‑static discharge (ESD) zones and cleanrooms. The paint’s rapid cure and propensity to clog traditional valves are mitigated by Dürr’s dead‑space‑free valve design and robust EcoPump9 series, delivering reliable flow even under demanding conditions.

From a business perspective, the automation translates into faster production cycles, lower labor costs, and higher repeatability, positioning Interstuhl to capture premium market segments that demand both design excellence and technical compliance. The scalable architecture also allows future expansion to additional colour palettes without major re‑tooling, reinforcing the company’s long‑term agility in a market where customization and compliance are increasingly decisive factors.
