| To achieve optimal results the length of a screen should be matched with multiples of the wire mesh grid center to center spacing. Wire mesh has a distinct tendency to force any shear action to occur in the mesh opening. If a dimension is selected that matches up with the center of an opening at one end, and the center of a wire at the other end (see Initial Screen Length in the illustration below), the result is an out of control process. The second cut is deflected along one side of the wire or the other, and has an adverse effect on subsequent parts.
Matching the length of a screen with multiples of the wire mesh grid center to center spacing brings greater control to the process, and when combined with the standard tolerance as calculated below will produce screens that statistically exhibit a near ideal bell curve.
To enhance your design specifications enter the mesh count warp direction, mesh count fill direction, wire size, and proposed initial screen length. The optimized screen length, standard tolerance, and other data is calculated and displayed below.
