Laser Marking Machine

What is a Laser Marking Machine?

A Laser Marking Machine is a device that uses a focused laser beam to permanently mark or engrave text, logos, barcodes, serial numbers, or graphics on various materials — such as metal, plastic, glass, wood, and ceramics.

It’s widely used in industries for product identification, branding, and traceability.

How It Works

The machine directs a high-energy laser beam onto the surface of the material.

The energy from the laser alters the surface — by heating, removing, or changing its color — to create a permanent and high-contrast mark.

Depending on the laser type and material, the marking can be done through:

• Engraving (removing material)
• Etching (shallow marking)
• Annealing (color change on metal surface)
• Foaming (raised marks on plastic)
