What is chemical etching?

Chemical etching is a manufacturing process that uses chemical etchants to machine precision components from sheet metals. It offers a cost-effective alternative to stamping, laser and water jet cutting.

How does chemical etching work?

The chemical etching process steps are as follows:

1. Choosing your material: Almost any metal can undergo photochemical etching – even those that are traditionally hard to machine.

2. Pre-clean: The metal is chemically cleaned to remove debris, waxes and rolling oils.

3. Lamination: An ultraviolet light-sensitive photoresist is applied to the metal.

4. Printing: Ultraviolet light passes through a phototool mask of the component design, transferring it to the photoresist.

5. Developing: The photoresist is selectively removed to expose the metal.

6. Etching: Chemical etchant is sprayed onto the sheet, dissolving the exposed metal.

7. Stripping: The remaining photoresist is removed to reveal the final etched component.
