The Complete Guide to Laser Marking: From Serial Numbers to Product Traceability

In today’s manufacturing world, precise and permanent product identification is crucial. Laser marking has revolutionized how we engrave serial numbers, logos, and barcodes on various materials. This comprehensive guide explores everything you need to know about laser marking technology, its applications, and how it’s transforming product traceability.

What Is Laser Marking and How Does It Work?

Laser marking uses a laser beam to create permanent marks on materials through various processes. The marking process involves focusing a laser beam onto the surface of the material, causing physical or chemical changes that result in visible markings.Different laser marking methods include:

• Annealing
• Engraving
• Etching
• Color marking
• Surface ablation

What Are the Key Advantages of Laser Marking?

Laser marking offers several benefits over traditional marking methods:

• Precision: Creates highly detailed and accurate marks
• Permanence: Marks resist wear and environmental factors
• Speed: Fast marking process for high-volume production
• Versatility: Works on multiple materials including metal parts and plastics
• Non-contact: No physical tool wear
