Engraved and Etched Tags Side by Side Comparison

Engraving vs. Etching: Which Do I Need?

Engraving and Etching are two excellent processes for metal nameplate production. They feature high customization and level of detail.

While they share some similarities, they also differ in areas as well. This guide will walk you through both processes to give you a better idea of which best fits your application.

Engraving

Producing engraved tags uses a specialized machine to directly carve a design or data into the metal material. Some manufacturers accomplish this by utilizing high-power laser engraving machines.

The design is cut deep into the material, resulting in a long lasting, and highly visible image.

One potential drawback to engraving is that it is a very time consuming process. Each individual element of the design has to be cut out of the material one tag at a time. For large quantity production, this is a nightmare.

Applications requiring extremely large quantities are better suited for a die process such as stamping or embossing.

Durability

Engraved tags feature high durability. The deeply cut design means that it will take significant wear and tear before the plate is no longer readable.

Another major benefit is not having ink to rub off or fade away. It also means engraving holds up in some rough environments.

While they are not on par with the most durable processes, they are still a very viable option.

Materials

  • Aluminum
  • Brass
  • Stainless Steel
  • Cold Rolled Steel

One of the most popular choices for engraved material is aluminum. It has some advantages over comparable metals. The anodization process creates not only higher durability and resistance, but also the option for colorization. Unlike some other material options, aluminum is very lightweight. However, it doesn’t sacrifice durability.

Stainless steel is another popular choice for engraved tags. This material offers the highest level of durability. It is able to hold up to some chemicals and/or wear, however it is significantly heavier.

Engraving typically requires the use of thicker material as the cuts it makes are significantly deeper than etching.

Engraved nameplates feature some customizable elements. For example, a custom logo added to an engraved design creates a stand out look. There is also the ability to colorize the tags through anodized aluminum, or painted steel. This will add a singular color to the material.

  • Shape
  • Holes/Thickness/Corners

Etching

Etching works a little bit differently than engraving. There are two main ways nameplates are etched: laser etching and chemical etching.

Laser etching is exactly what it sounds like. A high power laser cuts into the metal to create a lasting design. This can be anything from a basic image, a design, or even just plain text/numbers.

Chemical etching uses special chemicals to very carefully dissolve the metal substrate. The specified areas of the desired image are the only areas which receive this treatment.

Unlike engraving, etching is used on a wider range of material thicknesses.

Both chemical and laser etching result in durable designs that are easy to read.

Durability

Similarly to engraving, etching is a durable tag process. They typically last around 5-10 years. Compared to screen printing or decals/labels, this is much improved. No topical ink on the tag means no wearing and fading. However, ink fills that may be added are susceptible to wear and tear. This is something to consider when considering this option.

While the process is durable, there are a few drawbacks. One negative is the ease of obstruction. If dirt or paint cover the nameplate, it will be difficult or impossible to read.

If longevity is a main concern, other custom ID processes such as embossing or photo anodization last significantly longer.

Industries

Etched tags are used by a wide range of industries. From aerospace parts to military applications, the process has been adopted by many organizations.

  • Aerospace
  • Transportation
  • Energy
  • Defense
  • Furniture
  • Many More

Similarly to engraving, many materials are suited for the etching process. Aluminum and stainless steel are the most common and used in a variety of environments and applications.

Material

  • Aluminum
  • Stainless Steel
  • Cold Rolled Steel
  • Brass
  • Copper

Etch and Fill

One special benefit to this process is the ability to etch and fill. After the laser or chemical etching is finished, a color fill is added in the recess. This is a great way to further customize your nameplates.

One thing to keep in mind is that the color filling is not especially durable. It is prone to fading as well as being removed through abrasion or chemical contact. The etched design will last for several years, but the added color will not.

Wrap-Up

Engraving and Etching are two incredibly versatile options. They provide significant customization possibilities, and are suitable for many applications. Industries across the world utilize both engraving and etching. From Aerospace to Transportation, there are uses for every process.

Additionally, using anodized aluminum for color coding is a great way to easily identify assets or other equipment.

One feature unique to these processes is color infill. Creating colorized text and designs allows for new levels of customization. Keep in mind durability for the ink is not outstanding.

Etched tags offer high customization, but aren’t perfect for all applications.

While engraved tags are durable, they are also more time consuming to produce. They are a great fit for smaller size runs, but less viable when scaled.

At the end of the day, the best identification solution is the one that is right for your application. By working with your metal tag manufacturer you will find the perfect solution.
