Geiger Automotive adopts Rampf FIPFG sealing to automate gasket production
Geiger Automotive has adopted formed-in-place foam gasket (FIPFG) sealing technology from Rampf Group to improve the production of complex air-duct gasket frames, replacing a manual, material-intensive foam molding process with a more automated and efficient approach.
The company is using Rampf’s two-component polyurethane foam system, Raku PUR 33-1033-1, in combination with the C-DS RA mixing and dispensing system. Together, these technologies enable precise, automated gasket application, delivering higher process reliability and reduced material consumption.
Previously, sealing gasket frames with large width-to-height ratios using FIPFG technology was not feasible due to manufacturing tolerances in vehicle bodies. As a result, Geiger Automotive relied on molded foam that required manual application and die-cutting—an approach associated with high costs and significant material waste. By switching to FIPFG, the company can now dispense reactive polyurethane foam directly into a mold, where it expands in a controlled manner, adheres to the component, and forms a precisely fitting gasket.
The transition has eliminated manual processing steps while improving manufacturing efficiency, consistency, and overall product quality. Material usage and waste have also been significantly reduced.
The polyurethane system itself was developed for demanding series production environments. It offers strong adhesion and sealing performance, low Shore hardness with high elastic recovery, fast curing, and low water absorption. The material also features a compact integral skin and resistance to temperature, chemicals, and aging, making it suitable for applications requiring tight tolerances and complex geometries.
The automated C-DS RA system supports this process through controlled material dosing and high repeatability. The fully integrated production line comprises ten automated steps, including component loading, plasma treatment, gasket dispensing, thermal curing, and camera-based inspection. Non-conforming parts are automatically rejected, while approved components proceed without manual intervention. A dedicated release-agent system and optimized mold design ensure the gasket adheres only to the component and can be cleanly demolded.
Mario Haak, plant manager Tambach, Geiger Automotive, said: “Our ambition is to develop intelligent solutions for a mobile and sustainable future. The economic and environmental improvements achieved in this project clearly demonstrate this commitment and strengthen our position as a best-in-class partner in the development and manufacture of plastic system solutions. By combining the reactive resin system with the associated mixing and dispensing technology from Rampf, we have made significant progress in the production of air-duct gasket frames.”
