Laser marking
Laser marking on metal is a versatile and reliable technology that meets many industrial needs. The technology is used to create permanent markings on various metal surfaces. This technology is often used in industry to label products with information such as serial numbers, barcodes and logos.
Technology and process
The laser beam:
A high power laser is directed at the metal surface, which generates heat and causes a reaction in the material. Depending on the type of laser and settings, the marking can be done through different methods such as engraving, tempering, removal of material, or foaming.
Engraving:
The laser beam engraves a design or text by melting and vaporizing the surface layer of the metal, creating a deeper mark. This results in a durable label.
Tanning:
During tempering, the laser heats the metal to a temperature that changes the surface color without removing material. This is often used to create contrasting marks on metals such as stainless steel and titanium.
Material removal:
The laser is used to remove a thin layer of the metal, exposing the underlying surface and providing a clear contrast between marked and unmarked surface.
Foaming:
When foaming, the laser creates small bubbles in the surface of the metal, which gives a bright marking.
Advantages of laser marking
Precision and details:
Laser marking can create very detailed and precise markings, which is important for small text sizes and complex patterns.
Duration:
The markings are durable and resistant to wear, chemicals and high temperatures.
Speed:
Laser marking is fast, making it efficient for high-volume production.
Flexibility:
Can be used on various metals such as stainless steel, aluminium, brass, titanium and many more.
Environmentally friendly:
No use of ink or other consumables, minimizing waste.
Areas of use
