Fotofab’s chemical etching technology (photochemical machining) offers several benefits over traditional machining processes. We specialize in producing your parts featuring a trio of fundamental improvements over other manufacturers, including reduced costs, faster speeds, and higher precision parts.
Fotofab products are made in the USA and distributed worldwide.
Benefits of Photochemical Machining (Chemical Etching)
Benefits of Photochemical Machining (Chemical Etching)The affordable pricing, quick speed, and high precision of our photochemical etching process ensure that it is the quintessential method for both large production and quick prototyping of metal parts.
Inexpensive Phototools
Pricing for the majority of phototools used in chemical etching is thousands of dollars less than the cost of using hard tools for manufacturing equivalent metal parts.
Faster Production
Photochemical machining typically takes less than a day, often less than an hour, to complete. This means your custom parts are ready to ship the same day.
Standard lead times are between 5-7 days from the order date, with an optional expedited service available.
Higher Precision
Fotofab produces, stores, and uses the phototools in our in-house, temperature, and humidity-controlled clean room. The tools rarely leave this environment so there are no variations in size, and it remains consistent – as do we.
- Photochemical Machining or Chemical Etching has the ability to produce complex geometries within very strict tolerances, and the good news is that increased part complexity is very rarely a cost driver.
- Production Volume - We have the capabilities to help with your prototype and high-volume production orders.
How quickly do you need your photo etched parts? Fotofab can deliver. Delivery options may be specified on your purchase order.
The Photo Etching Advantage
Photochemical etching produces precision metal parts more precisely and with tighter tolerances than metal stamping, laser cutting, CNC machining, and wire EDM.
Chemical etching (photo etching) is a photo-lithographic process whereby a phototool is used to block UV light from exposing the area of a sheet of metal that has first been cleaned and laminated with photoresist. The sheet is developed which washes away the unexposed photoresist leaving a very precise mask of hardened photoresist behind. This patterned sheet is then exposed to concentrated etchants which very precisely dissolve any exposed material.
