Top 3 Ways of Part Marking You Must Know

When quality and safety are at stake, cutting corners on part marking is not an option. There are several methods available for part marking. Selecting the right method is crucial to ensuring that your parts are appropriately marked and meet all applicable standards.

Part marking options are meant to help identify a specific part from the larger inventory. It is important to know how a part marking option can help in identification or if it does at all. The main point to remember is that a part marking option is essential for nearly every part which is procured. Many manufacturing companies that offer part marking options in their surface finishing services

This blog focuses on the different part marking options that are commonly used for prototyping or custom parts manufacturing.

The reason for Part Marking. 

When it comes to part marking, there are a few key reasons why manufacturers do it. Let’s take a closer look at each of these reasons:

1. Part Marking Helps to Ensure That the Correct Part is Being Used

When it comes to assembly, it is critical that the correct part is used for the application. If the wrong part is used, it can lead to a number of problems, including poor performance, reliability issues, and even safety concerns. Part marking helps to ensure that the right part is being used by clearly identifying it. This can save a lot of time and money in the long run.

2. Part Marking Can Help to Improve the Reliability of the Product

Another key reason for part marking is to improve the reliability of the product. When parts are correctly marked, it helps to ensure that they are correctly assembled. This, in turn, can lead to improved performance and fewer issues over the life of the product.

3. Part Marking Can Help to Reduce the Overall Cost of Production

Finally, part marking can also help to reduce the overall cost of production. By clearly identifying the parts that are used in the assembly process, manufacturers can save time and money. This is because they can avoid having to stop the assembly line to search for the correct part.

Part marking is a crucial step in manufacturing

Laser Etching

Laser engraving involves removing material from a substrate through the action of an intense, focused light beam. The material removal may occur either directly (by ablation) or indirectly (through a chemical reaction).

In the case of direct ablation, the laser beam’s energy causes the target material’s vaporization, leaving a hole behind. Chemical reactions occur in the presence of the laser beam, causing a change in the physical properties of the target material. For example, suppose titanium nitride is exposed to a high-intensity laser beam.

In that case, the temperature rises sufficiently to cause the titanium atoms to break apart into oxygen and nitrogen gas. These gasses diffuse out of the area where they were formed and leave behind a void.

Laser engraving is a versatile marking process because it does not require ink or consumable materials. Because it works without any ink, it can be used to mark plastics. In addition, there is no need to purchase new equipment for each job.

You only need one machine and one type of laser. This means lower costs and fewer maintenance issues. When marks are made on parts, they last longer than those made with traditional methods. They do not fade or peel off over time.

Silk Screening

Silk screening is a popular method for part marking because it is quick, easy, and versatile. You can use silk screening to print on a variety of materials, including plastics, metals, and glass. Silk screening can also be used to create raised or recessed designs.

If you’re looking for a way to mark your parts with a logo, serial number, or other text, silk screening is a great option. Here’s a quick overview of the silk screening process:

  • First, a stencil of your design is created.
  • Next, the stencil is placed on the surface of the material you’re printing on.
  • Ink is then applied to the stencil.
  • The ink is forced through the stencil onto the surface of the material.
  • The stencil is then removed, leaving your printed design.

Silk screening is a great way to quickly and easily mark your parts. It’s versatile, durable, and can be used on a variety of materials. Give it a try the next time you need to mark your parts!

Laser Marking

Lasers offer the best method for creating durable, high-quality marks on metal, plastic, alloy, and other materials. Laser Marking is a non-contact process that uses a laser to mark the surface of a material.

The laser beam interacts with the material to create the desired mark. The type of mark that can be achieved is dependent on the laser parameters (power, wavelength, beam quality, etc.) and the material being marked.

Here’s a look at some of the advantages of laser marking for part marking:

  • Laser marking is permanent. Once a part is marked with a laser, the mark will be there for the life of the part. This is ideal for applications where it’s important to be able to identify a part, even after it’s been through years of wear and tear.
  • Laser marking is legible. Even small marks can be easily read with the naked eye, making laser-marked parts easy to track and trace.
  • Laser marking is low-cost. Compared to other marking methods, laser marking is very cost-effective.
  • Laser marking is fast. Laser marking can be done quickly and easily without the need for specialized equipment or training.
  • Laser marking is versatile. Laser marking can be used on a variety of materials, including metals, plastics, and glass.


Now we hope you understand what part marking is and why you need that. But one thing you should consider, part marking is a very delicate process. You don’t want to ruin the product by marking it, do you? Therefore, you must choose a company with quite a bit of experience in this field.
