What is Chemical Etching?

The chemical etching process is a tightly controlled subtractive manufacturing process that utilizes corrosive chemicals, known as etchants, to dissolve away unwanted portions of metal. When performed correctly, chemical etching is capable of producing highly complex, thin metal parts with very fine details and tight tolerances.

The chemical etching process begins by first thoroughly cleaning the metal to be etched, to ensure it is free of contaminants and debris. Metal is often cleaned with a degreaser to ensure it is free of oils and residue, rinsed, and then cleaned a second time with an acid wash to ensure the surface is free of any foreign contaminants. Finally, the metal is dried and inspected for cleanliness.

The next step in the chemical etching process is to laminate the freshly cleaned metal on both sides with a UV sensitive resist. In most metal etching, a negative photoresist is used, which polymerizes when exposed to ultraviolet light and protects the metal underneath against etching. To achieve the desired metal part, only certain portions of the resist are exposed to ultraviolet light, allowing the unexposed portions to be dissolved away.

After applying the resist, the next step in the chemical etching process is to position a phototool on each side of the coated metal sheet. The phototool consists of two pieces of special film that are printed with a negative image of the desired metal part and carefully applied to both sides of the metal to be etched. Those areas of metal to be etched away are printed black, preventing the areas underneath from being exposed, and those areas of metal that will form the desired part are clear, allowing ultraviolet light to penetrate and polymerize the resist beneath.

Next, the metal is exposed to carefully controlled ultraviolet light, which allows the selective hardening of the metal beneath the clear areas of the applied phototool. After the metal is sheet is developed, the unexposed areas of photoresist are washed away, leaving behind portions of unprotected metal.

Finally, the metal sheet undergoes the etching part of the chemical etching process, and is sprayed on both sides with a temperature controlled acidic etchant. The etchant dissolves away the unprotected portions of metal that were not exposed to ultraviolet light, leaving behind the desired metal part.

The last step of the chemical etching process is to run the etched metal through an alkaline wash and strip the remaining polymerized photoresist from the protected metal.

Engraving Alternatives

Engraving Alternatives

Metal engraving is done with either a tool or laser and the parts, in most cases, are done one at a time. This can be very expensive when running higher quantities. As an alternative Etched Metal Company’s chemical etching process is a viable solution with significant cost savings, shorter lead times and incredible detail.

The chemical etching process will achieve a depth of .003-.005 and under some circumstances we can perform a deep etch which can achieve a depth of .005-.010 depending on the image being used. After etching we can fill the copy with the color of your choice matching it as close as possible or leave it unfilled which creates a contrast between the two surfaces.

 

Stainless steel etch no fill

This is an example of an etch with no fill on heavy gauge stainless steel. There is a nice contrast to the copy and it is incredibly durable.

The example to the right shows an etch with a three color fill on mirror bright stainless steel.
This process requires some specific design requirements. We can not overlap colors and prefer to have at least 1/16th of an inch (.062) (1.55mm) between colors.

 

Etch filled black background on aluminum

This is an example of etching and filling the background. The process leaves your copy raised for a different look.

Chemical etching is a very durable and cost effective choice when you are in need of 10 or more nameplates. If the enamel were to be removed you still have a solid image which is the best option when you need to know what you are looking at years from now. It is a common nameplate design for nuclear waste containers, submersible equipment, military vehicles & equipment, asset & serial tags and the list goes on.
