Interview with DOPAG expert Guido Löhr about FIPFG

High cost-effectiveness and a wide range of applications for PU foam gaskets

Seals are used everywhere, in vehicles, electronics production or lights. In many cases, the seals are still inserted manually. However, automated application, the Formed-In-Place-Foam-Gasketing (FIPFG), offers many advantages.

In the case of a formed-in-place foam gasket (FIPFG), a highly reactive material is applied to a component automatically. The material, a polyurethane or a silicone, is metered and mixed using a dynamic mixing system and then applied along a contour. Following a reaction time defined by the material formulation, the material foams up and adheres to the component.

Form-In-Place-Foam Gasketing (FIPFG)

dynamic mixing with the dynamicLine

The PU gasket is applied with the dynamicLine from DOPAG. The dynamic mixing head processes the highly reactive material reliably and reproducibly, and a linear robot is then used to apply the seal.

Compared to manually inserted seals, there are numerous advantages, including time and cost savings as well as lower material consumption. The start and end points of the foam bead merge thanks to the controlled overlap programmed by DOPAG and there are no disadvantageous coupling points.
