Fotofab

Fotofab is a leader in photochemical etching, fabricating custom precision metal components from a long list of metals and alloys. Since 1967, we have worked closely with innovators in the medical device and implant industries to provide precision metal parts for applications of all kinds. Customers choose Fotofab time and again because of our fast turnaround times, rapid prototype ability, and accuracy to requirements. Not to mention our dedication to customer service and affordability.

Etched metal components in medical devices

In the medical industry, metal parts are used in a variety of devices, machinery, implants, and single-use tools. Fotofab has been integral in manufacturing etched parts for medical devices such as wrist plates, tendon snares, contacts for pacemakers, flat springs for buttons, PCB shielding, and metal filters. Other etched components have been used in monitoring devices, dialysis machines, anesthesia machines, implantable devices for incontinence, dental and orthodontic appliances, and MRI systems. We make sure to inspect each part before it leaves our facility to ensure the highest quality standards for safe and effective medical devices.

Tolerances for photochemical etching metal parts

Fotofab works with an extensive list of metals and alloys to fabricate etched parts for the medical industry. Stainless steel 300 series and exotic metals like titanium and Elgiloy are often requested for etched medical components. These metals begin as a flat sheet, typically 12″ x 18″ and between 0.0002″ – 0.0125″ thickness. The exact tolerances depend on the features of the part and the metal being etched.

Process of etching metal components

Photochemical etching creates components to exact specification but without altering the physical properties of the metal, like laser etching and stamping. The process uses a photoresist to mark a flat sheet of metal with the desired design. This sheet is then run through a single or double-sided acid wash to etch away the unprotected metal. The result is an etched metal part in the exact design requested. Photochemical etching allows these parts to remain in the sheet webbing for easy transport or removal for further processing or special packaging.

Additional services etching metal components

While our main product is custom-made metal components, we also understand the need for further finishing of a part before use. Fotofab offers a wide range of secondary services, like electropolishing and forming, in order to deliver a ready-to-use part. Forming is an in-house service that does not require an etched metal part to begin the process. Fotofab provides a full range of metal bending and forming services on a rapid delivery basis.

Quality certified metal etching

We are continually making efforts to improve our process for the benefit of our customers. Our premium sheet metal is sourced and processed in the United States. We are a Made in the USA company, and our parts help customers worldwide meet the highest quality standards and are proven reliable time and again. Fotofab is committed to quality and maintains the following standards: ISO 9001 and AS9100D certified, ITAR registered, RoHS and REACH compliance, and Conflict-Free Mineral policy.
