Laser Marking for Industrial Applications: All You Need to Know

Different types of laser marking

• Fiber Laser Markers — Fiber and MOPA laser markers stand out as highly adaptable tools for engraving a diverse array of materials. They excel in industries such as automotive, security, and medical manufacturing. Primarily designed for use on metals and plastics, these machines are low-maintenance and eliminate the need for consumable supplies, streamlining the marking process.
  
  
• Co2 Laser Markers — Renowned for their durability, Co2 laser markers are ideal for demanding applications and packaging labels. With the capability to mark up to numerous characters per second in automated setups, they significantly enhance efficiency while eliminating the reliance on consumables.
  
  
• Green Laser Markers — They’re an excellent choice for marking plastics and valuable metals like gold, copper, and silver, as well as for engraving electronic components, printed circuit boards, computer chips, and magnetic cards.
  
  
• Vanadate Laser Markers — Vanadate laser markers deliver superior beam quality, higher peak power, and an improved depth of focus compared to fiber lasers. They’re well-suited for marking heat-sensitive materials such as foils, plastics, silicon, and certain metals. These markers are particularly valuable for applications that demand consistent and precise results.
  
  
• UV Laser Markers — Often referred to as “cold” lasers, pico laser markers operate without generating heat, making them perfect for delicate and sensitive materials. Pico laser markers are ideal for applications where minimizing heat-affected zones is critical. They are capable of marking a variety of materials, including plastics and silicon, without additives. These lasers can also mark glass with reduced risk of micro-fracturing, delivering precise micro-markings with sharp resolutions.

How Laser Marking Works

The laser marking process is a sophisticated interaction between a focused laser beam and the surface of a material. Here's a breakdown of the common mechanisms through which laser marking works:

1. Engraving: engraving removes material to create deep, permanent marks. This is particularly useful for industries like aerospace and automotive, where parts are exposed to extreme conditions, and markings must remain legible.
2. Annealing: annealing heats the surface of metals without removing material, causing oxidation that results in a dark, high-contrast mark. This method is popular in medical and mechanical industries as it does not compromise the material’s surface or sterility.
3. Foaming: this technique involves melting the surface slightly to produce a raised, frothy texture. It is often used on plastics to create light-colored marks that are easy to read.
4. Color change: common in plastics, this process alters the pigmentation of the material itself, offering a cost-effective and clean way to create markings without removing material.

Each of these techniques provides unique benefits depending on the material and application, making laser marking a flexible solution for a wide range of industrial needs.
