Recent analysis shows that using electroformed filtration material significantly narrows particle size distribution, requires less maintenance and cleaning, allows longer filtration cycles and longer lifetime resulting in significantly higher production efficiencies compared to woven wire filtration materials.

Electroforming produces apertures in a rigid structure that does not deform. Hole dimensions can be held to very tight tolerances with little hole to hole variation over the entire surface. Unlike woven wire screens, electroformed filters have a flat, smooth surface. In addition, wire woven materials are available only in select openings. Electroformed materials are available at each micron increment between 3 and 2000um in square, round or custom geometries.

The weaving process employed in the manufacture of woven wire test sieves lends to fluctuations both in the nominal aperture size and the range of sizes in a given cloth. For example, a nominal 63-micron test sieve can vary from 56 – 69 microns and still be within specification. An electroformed sieve of the same nominal 63um would only vary between 61 and 65 microns ( 62-64 for the Ultra Precision Electroformed Sieve ).

Which do you require, electroformed materials or woven wire mesh? Regardless of your intended application, choosing the proper sieving medium is dependent on your specific requirement for accuracy and life cycle. While the wire woven option is economical, if it is precision you require - Electroformed Materials are the clear choice.
