Drill length to diameter ratio
WebL/D is the ratio of the length of magnetization direction of a magnet (L) to the diameter of the magnetization surface (D). For NdFeB magnets, L/D is of important reference significance for the preliminary judgment of the … WebL/D Ratio. The L/D ratio is the ratio of the flighted length of the screw to its outside diameter. The ratio calculation is calculated by dividing the flighted length of the screw by its nominal diameter. Although several injection molding machine manufacturers now offer a choice of injection units, most injection screws use a 20:1 L/D ratio.
