The hypothetical force is calculated in experimental configuration (a sphere above a disk both covered by two metallic layers). The strengthenings of constraints up to 4 times comparing the previous experiment and up to 560 times comparing the Casimir force measurements between dielectrics are obtained in the interaction range 5.9 nm$\leqλ\leq 115 $nm. Recent speculations about the presence of some unexplained attractive force in the considered experiment are shown to be unjustified.5 pages, 1 figureHigh Energy Physics - Phenomenologytext
