Normal dot peen engravers also have two types of designs — electromagnetic and pneumatic. The machines utilize interchangeable marking pins that quickly change the work mechanisms based on the operator’s requirements. Normal dot peen engravers work slower when marking delicate or fragile materials and work faster when marking tough or rigid surfaces.

A dot peen marking machine is used to imprint materials with a series of indentations to form permanent markings. This machine is most frequently used in industrial manufacturing applications when manufacturers need to mark products permanently. Industry standards or legal regulations could require permanent marking instead of printed labels, making a more durable type of marking necessary. Other types of marking equipment, like handstamps and etching pens, are not as efficient and might create poorer-quality markings.

Dot peen marking machines are powerful and versatile enough to mark on a wide range of hard materials, such as structural steel, aluminum and plastics. These machines may be pneumatic or electric. Dot peen machines use a pin to strike the material, creating a succession of dots that form letters, numbers or various other patterns, including:

  • Part numbers
  • Serial numbers
  • 2D data matrix codes
  • Barcodes
  • QR codes
  • Company logos

Manufacturers can select from various industrial dot peen marking machines or entry-level dot peen machines, which are ideal for smaller applications. The advantage of the industrial dot peen machines is their ability for greater depth and higher speeds—in addition, some with their multi-pin technology that enables faster operation. For example, the TMM5400 Dot Peen has eight individual pins and can mark up to 16 characters per second. Both industrial and entry-level dot peen marking machines can be enabled for benchtop use, while industrial machines integrate seamlessly into a production line.

Many types of dot peen marking machines are available, and it’s helpful to understand the difference between them to know which would best suit your applications. Below are the many options for dot peen marking and how they work:
