LASER MARKING: WHAT IS IT and how Machine works

LASER MARKING

Laser marking, in its simplest form, is a permanent process that creates a mark on a surface using a concentrated beam of light. Laser marking can be done with any of a variety of laser machines, including a pulsed, continuous-wave, green, or UV laser machine. These are the most popular types of laser marking:

  • Annealing
  • Carbon migration
  • Discolouration
  • Engraving
  • Etching

Laser marking is easy to automate and can be done at high speeds. Permanent traceability marks can also be left on a variety of materials including steel, titanium and aluminium, copper, and ceramic. Parts and products may be marked with text (including part numbers and serial numbers), machine-readable data, or graphics.

HOW LASER MARKING WORKS?

Laser marcatura uses a concentrated beam of light to mark a material’s surface. The material’s surface is altered by the beam’s interaction with it. Laser marking machines can create high-quality, high-contrast marks on any surface by focusing their laser beam only on a specific area. Laser marking is ideal for applications that require precision and permanence.

HOW LASER MARKING WORKS

Laser Science:

LASER stands for Light Amplification by the Stimulated Emitting of Radiation. Laser beams begin with an atom being stimulated to emit light particles. Laser marking areas can be created by concentrating the light. The wavelengths of the energy released are called nanometers (NM). The laser beam is stronger if it has a longer wavelength.

A UV marker has a wavelength of around 355NM and can mark heat-sensitive materials like plastic and glass with lower power. The UV laser marker and other machines belonging to the “cold laser” group emit less energy so they can be used for organic or soft products. The fibre laser operates at 1070 NM and can mark more difficult materials such as metal with significantly greater power.

Laser marking is more cost-effective than other marking methods like printing or labelling and requires less maintenance. For maximum system uptime and productivity, our team offers responsive customer service with a two-hour response time and free samples.

USE A LASER MARKER TO GET THE BEST BENEFITS:

Laser marking can bring many benefits to manufacturers, including part identification and branding as well as complete traceability that allows them to trace and track parts from cradle to grave. Laser marking machines can be used to direct part marking. These marks are durable and easily readable. These high-quality marks produce:

  • Increased operational efficiency and productivity, with less downtime and waste
  • Transparency and accountability throughout the supply chain
  • Reduced costly threats like quality and counterfeiting
  • Conformance to industry regulations

HOW TO USE A LASER-MARKING MACHINE?

There are many types of laser marking systems and each one works differently. The software that you are using and the material you are working with will affect the way you use the machine. MECCO provides a list of resources that will help you use your machine and solve any problems, including how-to videos and detailed documentation.

It is important to adhere to all safety guidelines when using any laser marking machine. Laser marking is relatively safe due to the availability of several safety precautions, such as safety enclosure options.
