Photoetched Parts

Small, light-gauge metal parts are photochemical etched to produce intricate components with close tolerances.

Formed parts are manufactured by combining photoetching for blanking with inexpensive or universal tooling for forming. Parts include encoders, masks, filters, lead frames, springs, strain gages, laminations, needles, heat sinks, shields, shutter blades, electron grids, fluidic circuit plates, reticles, drive bands, and shims. Parts may be fabricated from Nitinol, titanium, tungsten, molybdenum, copper alloys, beryllium copper, stainless steels, aluminum, Elgiloy, niobium, nickel alloys, silver, and spring steels. Parts range in thicknesses from 0.0005 in. and up.
