FAQ

Q1: What is chemical etching?

A1: Chemical etching, also known as photochemical machining (PCM), is a subtractive manufacturing process that uses chemical solutions to selectively remove metal from a sheet to create precise and complex parts. It relies on a photoresist mask to protect areas that should remain intact while the exposed areas are dissolved by an etchant. The result is high-precision, burr-free metal components with extremely fine details and tight tolerances.

Q2:How does the chemical etching process work?

A2: The process involves four main stages: (1) cleaning the metal sheet to remove contaminants, (2) applying and exposing a photoresist film with the desired design pattern, (3) developing the film to expose the areas to be etched, and (4) immersing the sheet in a controlled chemical solution that dissolves the exposed metal. After etching, the resist is stripped away, leaving a clean, accurately shaped metal part.

Q3: What types of materials can be chemically etched?

A3: Chemical etching is compatible with a wide range of metals and alloys, including stainless steel, copper, brass, aluminum, nickel, titanium, molybdenum, and Inconel. Each material uses a specific etchant formula and process condition to ensure optimal etch rate and surface finish. The process can handle metal thicknesses ranging typically from 0.01 mm to 2.0 mm.
