Expert Commentary
Measures Compression Force Deflection (CFD). Unlike the IFD test, which indents a large block, CFD tests a small specimen (50×50 mm) across its entire surface. This determines the material-specific firmness rather than the part-specific comfort. MTO’s focus is on the Hysteresis curve. By measuring the energy lost during a compression/decompression cycle, our software helps automotive engineers determine the damping characteristics of a foam, which directly affects the ride quality and vibration isolation of vehicle seats.
