Difference between laser marking and dot peen marking

2022-09-21

The principle of the laser marking machine is that the laser beam with extremely high energy density is irradiated on the surface of the product under the control of the computer, and the surface of the product is instantly melted or vaporized, thus leaving the concave marks we need on the surface of the product.
The principle of the pneumatic marking machine is to input the content we want to print into the computer, and the computer converts it into a digital signal and transmits it to the controller. Leave a concave mark on the surface of the product.

Laser marking machines have a wide range of applications, while pneumatic marking machines are mostly used for metals, and a few are used for non-metals (must be non-metals with relatively high hardness). And in terms of the degree of printing, pneumatic marking is not as beautiful as laser marking, but pneumatic printing is relatively deep. If you need to print very deep on metal, pneumatic (for example: frame number, etc.) is generally selected, and it is required to be beautiful. Or products that require relatively high precision will generally use lasers.
