WHAT IS LASER MARKING?
laser marking is a permanent process that uses a beam of concentrated light to create a lasting mark on a surface. Typically performed with a fiber, pulsed, continuous wave, green, or UV laser machine, laser marking encompasses a wide variety of applications. The most common types of laser marking applications are Annealing, Carbon Migration, Discoloration, Engraving, and Etching.
Laser marking can be automated and processed at high speeds, while leaving permanent traceability marks on a range of materials, including steel, titanium, aluminum, and copper. Parts and products can be marked with text including serial numbers and part numbers; machine-readable data such as barcodes and unique ID codes; or graphics.
HOW LASER MARKING WORKS
Laser marking works by using a focused beam of light to mark the surface of a material. When the beam interacts with the material’s surface, it alters the material’s properties and appearance. This concentrated beam targets only a specified area, allowing the laser marking machine to create precise, high-quality, high-contrast marks that are easy to read or scan on virtually any surface. This feature makes laser marking ideal for applications where accuracy and permanency are critical to success.

THE BENEFITS OF LASER MARKING
Previously, when manufacturers had to mark a surface with a pattern such as a barcode, image, or text, they had to choose between traditional engraving or screen printing. These processes, though, were costly, nonpermanent, and often damaged parts.
Laser marking has become an essential part of the manufacturing industry; helping businesses keep track of their products, improve quality, minimize counterfeiting, and more. To help understand the potential behind this technology, we’ve laid out the benefits of laser marking in manufacturing.
CLEAN AND ECO-FRIENDLY
Other marking processes, such as inkjet or chemical etching, use inks and chemicals in their marking, which not only are expensive consumables for the business but have a negative effect on the environment. Laser marking, on the other hand, does not use any consumables, making it clean, affordable, and energy efficient.
ENHANCE MARK QUALITY AND PERMANENCE
Laser marks are more durable and consistently readable than non-permanent marking alternatives for a wide variety of applications, from industrial traceability to branding, on materials such as steel, copper, aluminum, and brass. Lasers can also provide low or high-contrast marks to meet your visual standards through a range of settings.
INCREASE PRODUCTION SPEED AND EFFICIENCY
Laser engraving is a fast and simple process. Laser marking does not involve a physical tool impacting the surface, nor does it transmit ink or any other substance onto the surface. Instead, the laser light is focused onto a material, which in turn produces a contrasting mark or a deep mark, depending on the settings you use.
