Hutchinson Technology Inc. (HTI) has announced the availability of thinner stainless steel filter screens with smaller features. The filters are 0.025mm thick stainless steel, with 0.055mm diameter holes for volume production. Prototypes are available with even smaller hole sizes. The company has been providing filter screens for over ten years on stainless steel material that typically ranged from 0.040mm to 0.250mm thick. Applications include screen print stencils, hydraulic valves, medical devices, particle separation, sugar filtration, and various other critical filter processes. The stainless steel screens offer enhanced strength and more uniform hole size compared to alternatives such as wire mesh, because they are photochemically etched from a solid piece of stainless steel.
