Etched & Formed Precison Parts

Fotofab has been making custom metal parts since 1967, working with leaders in the medical, industrial, aerospace, semiconductor, and defense industries. They specialize in a unique manufacturing process called photochemical machining (PCM), also known as chemical etching or milling. Fotofab achieves lower tooling costs and quicker lead times than other traditional manufacturing methods like stamping or laser cutting, which can have costly tooling. Metal parts manufactured in the etching process can be turned around in as little as one day with extreme precision.

Fotofab is able to fabricate metal parts from sheets of Titanium, Stainless Steel, Copper, Tungsten, Brass, Inconel, and hundreds of other metals. With a minimum order quantity of two sheets each at a maximum of 24 x 36 inches, both prototype and production runs are processed side by side. Depending on the part design (through etch vs. half etch), they can produce parts ranging in thickness from 0.0001 to 0.125 inches.

Along with etching, Fotofab offers many value-added services. Common requests include forming, stamping, diffusion bonding, plating, and heat treating. These services are available to most Fotofab manufactured parts. They will deliver your parts complete and ready-to-use.
