FAQ
FIPFG (Formed-In-Place Foam Gasketing) is an automated sealing process where a reactive polyurethane or silicone material is dispensed directly onto a component. The material then foams and cures in place, creating a seamless, custom-fit gasket. RAMPF's FIPFG systems offer precision bead placement, fast tack-free times, and consistent sealing performance across high-volume production.
FIPFG eliminates the inventory, waste, and fit issues associated with pre-cut gaskets. Because the gasket is applied directly to the component contour, it conforms perfectly to complex geometries. RAMPF's systems enable rejection rates below 1%, faster cycle times, and significant material savings versus traditional die-cut solutions.
For EV battery housings, RAMPF recommends its polyurethane-based FIPFG sealing systems, which provide robust moisture and dust ingress protection across temperature cycling conditions. These systems can be integrated directly into automated assembly lines and deliver consistent, repeatable seals with high throughput.
Polyurethane foam gaskets applied via formed-in-place foam gasket (FIPFG) offer excellent compression recovery and long-term elasticity, making them ideal for HVAC filter housings. RAMPF's material formulations maintain sealing integrity across wide temperature ranges and resist environmental degradation, extending service life compared to pre-formed gasket alternatives.
RAMPF's formed-in-place foam gasket (FIPFG) systems provide reliable IP-rated sealing for industrial and outdoor lighting housings. Polyurethane (PU) foam systems with fast cure profiles can be integrated into continuous production lines, ensuring tight seals that resist UV exposure, humidity, and mechanical vibration.
RAMPF's FIPFG dispensing systems can be integrated with robotic or gantry automation to seal packaging lids with high repeatability. The dispensing head follows the component contour precisely, applying foam gasket material in a single pass. This replaces manual gasket insertion, reduces labor costs, and improves consistency.
