What Is Serial Number Marking?
Serial numbers are unique identifiers in the form of codes containing typographical symbols like letters and numbers. Companies use these sequences to identify products and derive valuable data to ensure manufacturing traceability.
Serial number marking permanently modifies a surface using a specialized machine. The goal of this treatment is to create clear, readable serial numbers that are easy to scan and interpret.
Marking Processes
There are numerous ways to incorporate serial numbers onto products, each of which has different characteristics and applications.
Laser Engraving
Laser serial number engraving physically removes the surface of a material to produce a permanent mark using a laser beam. This process creates robust serial numbers that can withstand harsh operational and environmental conditions.
Serial number laser engraving is a preferred marking method due to its easily readable, high-contrast markings and extensive material compatibility. Though laser engraving is slower than other laser marking processes, it yields tougher, more durable results.
Laser Etching
Laser etching uses a laser beam to deliver high amounts of energy to a small area. As the laser heats the material, the surface begins to melt and expand, creating permanent raised marks.
Typically, the etching process is faster than engraving because it requires less laser energy. However, this serial marking technique has fewer compatible materials than laser engraving.
Stamping
Stamping is not a laser marking process, but rather, a dot peening technique, which fires a pin at high speeds using stepper motors and precise pin locations instead of laser energy to create serial number markings. Dot peening uses a pneumatically or electrically controlled stylus or pin to indent the material.
Stamping is a dot peening procedure common with metal marking. It creates marks by using a solenoid valve to fire a pin at high speeds. This makes an impression in the material that forms characters. Stamping typically requires a flat, solid surface to yield high-quality results, but Telesis Technologies, Inc. has developed a floating pin that allows the machines to mark on curved and irregular surfaces.

Choosing the Right Machine for Serial Number Engraving
Determine the serial number marking method that’s best for your application by considering the following factors:
- Material type: Evaluate your intended material type, its hardness and how it reacts to thermal, mechanical and chemical stress.
- Marking depth: Think about the marking depth capabilities of each serial number marking machine to ensure optimal readability.
- Clarity: Be sure the method you choose produces permanent, legible and precise markings.
- Portability: Consider whether you want a portable or stationary machine based on your needs. You should also verify that your system is easy to set up.
- Software: Invest in a marking solution that has user-friendly software with the proper editing functions.
