Marking Technologies: Laser vs. Dot Marking?

Marking Technologies: Laser vs. Dot Marking?

Make your choice with Technifor.

In this blog we shall take a brief look at some of the industrial differences in the area of qualities and functionalities on offer by using our robust range of Dot Marking Machine and Laser Marking Machines.

Whatever you desire from these two categories of marking machine, there is always a choice for you at Technifor. Here is a quick low down on the two categories

•  LASERS, normally provide a more precise mark than a Dot marker, or any other dot peen marker. Since the precision of the mark is an important factor in machine readability, this results in better readability for laser marking in certain applications.

•  Most Dot peen markers cost considerably less than laser markers. Our investigation reveals that most dot marker is in the range of $8,000-$20,000 while laser markers are generally higher.

•  Dot Marker or peen markers imprint a round dot; whereas a laser marker is capable of marking a square cell. This functionality adds enhances the relative readability of laser marks particularly in 2-D applications, because a perfect Data Matrix® 2-D code is based on square cells.

•  Dot Marker utilizes much smaller components than a laser marker, making it easier and less costly to integrate.

•  A laser marker is almost always much faster than dot marker or any other dot peen marker.

•  Dot peen marks are widely accepted by the aerospace industry for marking critical parts. Laser markers are typically not suitable for this kind of task. This makes dot marker more of an industry specific choice. Analysis reveals that the cross-section of a generic dot marker peen has no sharp corners, but with gentle curves, thus resulting in no significant stress concentration. However, laser marking can adversely affect material properties in the heat-affected zone of the mark, which can potentially result in the propagation of cracks in certain materials.

•  Dot marking are generally low contrast marks, which relies solely on illumination techniques to create the contrast required for marking. On the other hand, in some applications, laser marks produce higher contrast, which enhances their readability.
