Photo Etched Filters

As an ISO 9001:2015 certified company, E-Fab photo etched custom filters and filter supports for a wide range of applications, including metal-mesh optical filters, medical implants, fuel filters, air intake and supply filters, hydraulic valve screens, laser light filters, extruding screens, and more. Photochemical etching offers unlimited design flexibility and complexity to custom fabricate mesh filters to the exact specifications and requirements, including material and web thickness, pattern and spacing, and hole size and shape, including square, hexagonal, round, and conical.

This process also affords a number of design and process advantages. We can photo etch custom filters that have special features, various opening sizes, and degrees of transmission that can be controlled with micron precision. Because photochemical etching removes metal simultaneously, we have the flexibility to provide design solutions that cannot be achieved using other manufacturing methods. For example, we can solve transmission issues, incorporate multiple aperture geometries, vary bar sizes, and provide far greater open areas to control flow rates and characteristics. Also, our photochemical etched filters feature consistent cross-sectional thickness and accuracy of hole shapes and sizes. When fabricating larger or wider filters, additional webbing can be designed into the filter to give extra strength and support. Finally, tooling for photo etching can be manipulated on screen, which drastically reduces lead time and production costs.
