Meshes, filters and screens

Published: 1-May-2003


Design engineers and OEMs can now take advantage of the accurate and flexible manufacturing processes offered by Tecan Components to produce bespoke high-resolution metal meshes, screens, filters and sieves.

Custom designs can be produced using new high-accuracy photo-tooling methods, which bring sharper aperture edges and higher resolution. Designs can be simple or complex and contain holes and matrices of varying sizes and shapes, dependent on the end-user requirement. The new techniques mean that far larger surface areas can now be produced, while development and prototyping costs are reduced.

Using highly accurate photochemical machining or photo-electroforming, mesh membranes can be produced as flat sheets, as flexible membranes, or in three-dimensional forms. The durable screens are easy to clean and can have various surface textures - such as bright, semi-bright, matt, smooth or brushed. Accurate production techniques mean that hole sizes can be as small as 6µm across, and edge definition can be to within ±1µm. There is no need for subsequent machining or polishing after manufacture.

Unlike traditional woven products, the single-sheet screens do not have cross-over areas, which eliminates contamination due to trapped debris and delamination at the edges, as well as offering consistent cross-sectional thickness and consistently accurate aperture sizes.
