6. Dot peen marking can be done on many materials

Dot peen marking is mainly used on rigid plastics and metals. But the list is not exhaustive.

Two important rules need to be followed to know if it is possible to mark a material or not:

• The hardness of the material should not exceed 63HRC: marking hard materials such as carbide is quite possible.
• The materials must have a high enough deformation threshold to have a net impact on the part. If not, the surface will revert to its original shape or show unwanted chips. Dot peen is not designed for materials such as glass and rubber (but everything can be tried by our team!).

7. Low maintenance and easy to execute

One of the advantages of dot peen marking is that there is very little maintenance required. The only consumables are the stylus, becomes worn over time due to impacts, and the stylus reset spring. Stylus are made of tungsten carbide, which gives them a very long life. Maintenance is therefore reduced and very easy to perform.

8. A technology that does not generate any material chips or breakage initiators

Thanks to the deformation of the material due to the impact of the stylus, the marking becomes permanent and therefore has a better resistance to the wear and to the falsification of the marking. Some people might think that this could damage their parts during marking, which is a common misperception. Dot peen marking does not remove any material, which guarantees the strength and resistance of the part.

9. Marking that can be done even on non-flat surfaces

Dot peen has seen many evolutions and technological advances since its creation. In particular, the marking of non-flat surfaces is now possible with a difference in level of up to 5 mm. It is then possible to mark curved surfaces such as cylinders for example or angular surfaces while keeping a constant marking depth. For this purpose, Technomark has developed its patented IDI (Intelligent Driving Impact) technology, which perfectly meets this need.

10. Accessories and customization to meet market needs

With almost 25 years of experience in the industrial marking industry, we have learned that each project is unique. That’s why our range of dot peen machines also comes with accessories. For example, it is possible to equip the machine with a protective bellows for dusty environments, to adapt the number of controller outputs according to your needs, to add 2D code reading equipment to verify each marking, to use a clamping system or to install a rotary axis in order to mark parts on the median as well as on the circumference.

Despite the list of available accessories, it is possible that certain uses go beyond these configurations. Our design office then works on customized solutions to meet these needs perfectly.

You are now (almost) a marking expert! To go further, don’t hesitate to contact us.
