European photo etching specialist, Precision Micro will be exhibiting at FILTECH, the world’s largest and most influential filtration event, held in Cologne, Germany 13-15 March 2018. On stand U14 in Hall 11.1, Precision Micro engineers will be available to discuss the photo etching process for the manufacture of precision metal parts.

When applied specifically to the manufacture of filters, photo etching, the company says that lead times are reduced dramatically compared to traditional sheet metalworking, as are contingent costs, as tooling is digital, meaning set up and design iterations are quick and simple, and the resulting parts are free from stresses and burrs.

Special features

Special features such as conical holes and complex aperture arrays can be incorporated without cost penalty, as with photo etching component features are machined simultaneously meaning you only pay for the first hole.

Using the photo etching process, Precision Micro claim that it can produce filters in almost any metal, including hard-to-machine metals such as titanium and aluminum, and varying bar sizes and open area ratios can be incorporated to control flow rates across the filter.
