Here is a structured breakdown of Laser Marking Machines covering their types, key features, and industrial applications, especially relevant for traceability, branding, and compliance in Indian manufacturing environments.
What Is a Laser Marking Machine?
A laser marking machine uses a focused beam of light to permanently mark the surface of a material. Unlike printing or labeling, it alters the material itself through heat, oxidation, or ablation, creating high-contrast, durable marks like barcodes, serial numbers, logos, or QR codes.
Types of Laser Marking Machines
