You’ve made the decision to either start or improve your marking capabilities. Maybe a key customer is now requiring it, or you need better quality control and traceability, or you want to avoid breaking your thumb when hand stamping goes wrong. At the same time, you want a portable solution because of the size of your parts, the layout of your facility, or to improve productivity.

Regardless of your reasons, the next step is determining which type of portable marking solution best fits your needs. We’ll discuss two options: dot peen and laser.

Dot peen marking is a process of puncturing (or “peening”) with small dots on the surface of metal, aluminum, plastic and other materials at various levels of force. Numbers, letters, characters, data matrix codes, and logos can typically be programmed into dot peen marking units, which are then embedded in the surface. Some common dot peen marking industries are: automotive, aerospace, trailer manufacturing, oil & gas, metal fabrication, and steel production, among many others.

Durable Marking

Dot peen marking units offer portability to varying degrees. Our portable dot peen solution, the FlyMarker® mini, offers full battery-operated portability in units weighing just 5-7 lbs., depending on the model. Most other handheld dot peen units require cords or cables which can restrict portability and efficiency, especially in large facilities or when marking large parts. While we do offer tabletop units (and the FlyMarker® mini can be converted to a tabletop unit), the beauty of a battery-operated solution is that you can take the unit to the part for marking instead of the other way around.


Laser marking, on the other hand, marks standard text and numbers as well as more intricate designs, logos, barcodes, and images. A laser marker offers precision designs without puncturing the surface, which can meet marking requirements in certain industries such as medical, food production, or aerospace. Laser marking units are also used in a variety of other industries, some of which overlap with dot peen, including automotive, firearms, cutting tools, pipes and valves, among numerous others.

MobiLase Sample Picture

A quality fiber laser marker supports continuous, high-volume marking. Our powerful 30W portable unit, MobiLase, delivers rapid marking over an estimated 100,000-hour laser source lifetime. It’s uniquely portable, delivering all-in-one laser marking in a 45-lb. rolling suitcase. The plug-and-play unit features a 7-lb. handheld applicator for consistent, repeatable marks and a touchscreen PC embedded in the suitcase. By simply adjusting a few intuitive commands, you can laser mark on a wide range of materials ranging from steel to aluminum to plastic to varnished materials.
