What we do

Chemical etching shapes thin metal sheet by dissolving the unwanted metal through a photographic mask. Nothing cuts or presses the sheet, so parts stay flat, burr-free and stress-free, and no hard tooling is needed. This makes it well suited to prototypes, small and medium batches, and intricate parts that are difficult to stamp or machine.

We etch stainless steel, copper, brass, aluminium, titanium, nickel, carbon steel and glass. An overview of materials and design limits is on our metal etching service page.

Engineering guides: design guide, cost factors, etching vs laser cutting and our prototype service.

Our equipment

The three machines below carry out the core steps of the process: coating the sheet with photoresist, exposing the pattern, and etching the metal.

Conveyorised spray chemical etching machine line in the Golden Eagle workshop
Chemical etching machineConveyorised spray etching lines dissolve the exposed metal from both sides of the sheet at a controlled temperature, pressure and conveyor speed.
Photoresist coating machine applying blue photoresist to metal sheets
Photoresist coating machineThe coating machine applies an even layer of light-sensitive photoresist to the cleaned metal sheet before exposure.
UV exposure machine with vacuum frame and touch-screen control
UV exposure machineThe exposure machine transfers the part pattern from the phototool to the photoresist with UV light, which sets the accuracy of the finished part.

The full sequence, from cleaning the sheet to final inspection, is explained in the etching process step by step.

How we work with customers

  1. Drawing review. Send a DXF, DWG, STEP or PDF drawing with the material, thickness and quantity. We check manufacturability before any tooling is made.
  2. Quotation. We confirm the process and return a quotation.
  3. Phototool and samples. The pattern is made as a phototool, so samples are fast and design changes are inexpensive.
  4. Production and inspection. Parts are etched, stripped, cleaned and inspected before packing.
