Photo Chemical Milling Service
Photo chemical milling is a process that produces 2D part shapes by creating a chemical resist mask on the surface of sheet metal and chemically dissolving material from unmasked areas.
Whether you need a single part, batch of prototypes, or full production order, eMachineShop will turn your design into fully machined, end-use parts!

Photo chemical millingoffers high precision and detailed shapes in thin metal sheets, free of burrs. The process is particularly competitive for complex shapes.
Applications include gaskets, electrical shields, works of art, optical interrupters, shims, eraser shields, etc.
The process can also be used for etching which is similar to engraving.
- High precision and detailed shapes
- Free of burrs
- Competitive for complex shapes
- Complexity does not increase part cost
- Minimize thickness and part area
- Smallest diameter hole or slot must be similar to the sheet thickness
- Compensate for fitting into square hole by using radii corner reliefs
Photochemical milling is a popular choice for many metal products and components:
Photo Chemical Milling Parts
One of the most popular aluminum alloys used in sheet metal fabrication. It is readily bent, punched and sheared.
Known for its high corrosion resistance, especially in ocean water. Common applications include marine and aircraft equipment, fuel lines, street lights, household appliances, flooring panels, and railings.
Used in applications requiring high strength to weight ratio, and has good fatigue resistance. It is not weldable and has average machinability.
Corrosion resistance is poor. Widely used in aircraft structures, especially wing and fuselage structures under tension.
Has generally good mechanical properties, and is heat treatable. Highly weldable although strength near welds can be diminished by up to 30% if not subsequently heat treated.
Mostly used in extruded shapes for architecture, including window frames, door frames, roofs, piping, tubing and furniture.
Strong, with good fatigue strength and average machinability, but is not weldable and has limited resistance to corrosion.
Cost is relatively high compared to other Aluminum alloys. Often used in aircraft including wings and fuselages, rock climbing equipment and bicycle components.
