|How to determine the specification of Wire Mesh?
By several basic concepts: Mesh, Aperture size (w), Wire diameter (d), Pitch (t), Mesh thickness.
Mesh count is calculated upon the number of apertures per English inch (25.4 mm).
Wire cloth with square or right angled apertures should be described using actual aperture size (w) and wire diameter (d).
The open area describes the sum of all apertures as a percentage of the entire surface area.
Mesh thickness is a controlling factor in screen printing. It is based on the wire diameter and the weaving process. Thickness measurement is carried out prior to tensioning using a sensor, measured pressure 1/8N, on a rigid, flat substrate. The quoted tolerances correspond to a maximum value across the entire SD mesh output. Within a single roll, fluctuations are significantly less.
