Laser marking on metals
Metal is the material on which the laser has its best effect. All types of metal can be marked. Laser marking and engraving on metals ensures an accurate and clean result.
At the industrial level, there is no more efficient technology than the laser. Laser marking is a noncontact process that requires no intervention and allows for optimized production time.
With laser marking, the metal component is not damaged, and the result is also resistant to acids and other corrosive chemicals.
Steel is a versatile and durable material. Essentially made of iron, there are thousands of different types of steel that are produced to perform a particular job with very precise conditions. In fact, it is used in the construction and automotive industries, but also by food can manufacturers and appliance manufacturers.
Aluminum is a strong, lightweight material that is easy to combine with other materials and is resistant to heat and corrosion. It can be combined with other metals such as copper to make something strong and suitable for aircraft or automobile parts. Combined with magnesium, on the other hand, makes it a good material for food packaging and becomes perfect for packages to be molded and sealed. Aluminum’s adaptability makes the metal useful for many industries, from packaging to heavy industry. The MOPA laser is particularly effective in high-contrast marking because it only changes the color of the steel, without removing any material. CO2 and fiber can be used for etching and high-contrast marking on anodized aluminum, respectively.
In conclusion, the most suitable laser technology for laser marking of metals is the Fiber laser. It is also suitable for painted metals and metals with surface treatments such as anodized aluminum. The Fiber laser is used in both its standard version and the MOPA version which allows significant advantages in versatility and marking quality. With the Fiber MOPA laser it is also possible to mark in color.
