What is laser marking?
First, “laser marking” refers to the use of a laser beam to mark a workpiece and material.
Therefore, different processing methods will be different, such as engraving, removal, coloring, annealing and foaming.
And, each processing method has its own advantages and disadvantages depending on material and quality requirements.
Fiber laser marking machine advantages
1. High-precision marking, stable quality
Thanks to high-precision laser marking, even beautiful graphics, single-point fonts and extremely small graphics are clearly legible.
In addition, marking with a laser device ensures consistently high quality results)
2. High speed marking
Laser marking is one of the fastest marking processes on the market today. This will increase manufacturing productivity and cost advantages.
Depends on the material structure and size. Different lasers (such as fiber lasers or carbon dioxide lasers) or laser devices (such as galvanometer lasers) can be used to increase speed.
3. Durable mark
Firstly, laser etching is permanent, resistant to corrosion, heat and acid. Secondly, depending on the laser processing parameter settings.It can mark special materials without damaging the surface.
What materials can laser machine mark?
Firstly, Metal: stainless steel, aluminum, gold, silver, titanium, brass, platinum or copper
Secondly Plastic: ABS, polycarbonate, polyamide, PMMA or plastic with laser additives
Fourth,Aluminum foil and film and packaging
Last but not a list, different types of laser equipment used for marking (solid-state laser and CO2 laser equipment) depends on the material
The principle of fiber laser marking machine
1. Annealed Mark
Annealing Mark is a special method of metal laser etching.
In addition,the thermal effect of the laser produces oxidation under the surface of the material. It resulting in a change in the color of the metal surface.
Firstly, In the coloring method, the thermal effect of laser formation causes a chemical reaction in the material.
Secondly, depending on the composition of the material, it will form a different color.
For example, in laser etching, the light colored plastic material will change color and the resulting soot particles will leave a dark mark.
