What is Chemical Etching 

2 minutes read

Chemical etching, also known as chemical milling or industrial etching, is a subtractive manufacturing process that uses baths of temperature-regulated etching chemicals to remove material from a metal surface, creating an object with the desired shape. This process is commonly used in the manufacturing of precision parts and components for industrial purposes. It is renowned for its ability to create parts that are highly complex and difficult to manufacture with traditional methods. 

Here’s a detailed look at each step involved in chemical etching.

1. Material Selection

The first step in the process is to choose the right material. A wide range of metals can be chemically etched, including steel, stainless steel, copper and its alloys, nickel and its alloys, aluminium, and titanium. The metals can range in thickness from 0.010 mm to 1.5 mm and sheet sizes up to 600 mm x 1500 mm. The material selection will depend on your specific application requirements.

2. Pre-Clean

After the material is selected, it undergoes a rigorous cleaning process. This involves removing debris, waxes, and rolling oils that could interfere with the chemical etching process. The cleaning ensures that the metal surface is free from any contaminants that might affect the final result.

3. Lamination

Once cleaned, a light-sensitive photoresist is laminated onto the metal sheet. This step is crucial for the precision of the finished product. Poor adhesion could lead to blemishes or inaccuracies during the process, as it might allow the etchant to come into contact with areas of the metal that should remain protected.

4. Printing

In the next step of the process, a photo-tool mask containing the desired design is prepared, and the laminated sheet is exposed to ultraviolet (UV) light. This transfers the component design onto the photoresist, which undergoes a chemical change upon exposure.

5. Developing

The sheet is then developed to remove the unexposed photoresist, revealing the raw metal where the etching will occur. The hardened areas of the resist will protect the metal during the etching process.

6. Chemical Etching

Chemical etching agents, commonly using ferric chloride, are applied to the prepared metal sheet. Experts meticulously calculate the duration for which the sheet should be etched, considering factors like the kind of metal, its quality, thickness, and dimensions, as these elements influence the final outcome.

7. Stripping

After chemical etching, the remaining photoresist is stripped away to unveil the finely etched components. This reveals the intricate designs that have been chemically etched into the metal.

8. Visual and Dimensional Inspection

After the chemical etching process is over, each component is subjected to rigorous visual and dimensional inspection using advanced optical inspection equipment to ensure that it meets the desired specifications.

Benefits of Chemical Etching

The following are the several benefits of using chemical etching as a manufacturing process:

Precision Manufacturing

It is capable of producing intricate designs and tight tolerances due to the ability to selectively remove material from the metal sheets. This makes it ideal for creating high-quality precision components that require accuracy and repeatability.

Cost-Effective

The process is a highly efficient manufacturing process that can produce large quantities of precision components quickly and cost-effectively, without the need for expensive tooling. It is the perfect choice for those looking to increase production volume while reducing manufacturing costs.

Versatility

Its versatility in working with a wide range of materials allows people to choose from a range of suitable materials for their specific application. This adaptability ensures there is no compromise on quality or accuracy, making it a popular choice for those looking to produce components that meet strict specifications and high-quality standards.
