Permanent, Precise and Fast

Depending on the substrate, we use five different high-speed laser marking systems: green laser marking, YAG, UV, Co2 and fiber lasers.

High quality, permanent markings
Works on irregularly-shaped surfaces
Non-contact marking method
Precise and efficient

Types of Laser Marking We Perform

Annealing: The laser heats the substrate creating a thin oxide layer. Adjusting the power to the laser produces different colors.

Engraving: Removal of material to depth. Used primarily for steel and aluminum. Limited use for plastics.

Etching: Very light engraving – small removal of material.

Material Removal: Rather than traditional masking methods for anodize , laser masking removes the anodized aluminum layer on aluminum, leaving a clean, clear mark.

Change in Color or Bleaching: Commonly used for plastics, the laser changes or removes the molecules or additives, shifting the color or bleaching the substrate.

Foaming: Suitable for some plastics, the laser causes localized melting, creating bubbles that quickly cool to create the raised marking.

Masking: Used to remove anodize in specific areas for grounding purposes.

Annealing	Dark surface marking. Used primarily on uncoated steel and aluminum.
Etching	Very light engraving - small removal of material
Engraving	Removal of material to depth. Used primarily for steel and aluminum. Limited use for plastics.
Ablation	Removal of coatings like anodize
Color change	Used mostly on plastics to produce a contrasting mark
Foaming	Used on plastics to create a raised surface marking
Bleaching	Used only on Hardcoat anodize (primarily black). Creates a white marking by altering the dye. Does not remove anodize.
Masking	Used to remove anodize in specific areas for grounding purposes.

FAQs

A marking technique that does not penetrate below the material surface. This technique is ideal for industrial part marking and metal part marking, on delicate materials.

The difference between the laser marking technique and engraving or etching is that marking does not penetrate below the material surface, which is ideal for applications involving thin or delicate materials. Engraving penetrates more deeply into the substrate.

Yes, most plastics can be laser marked. If the properties of the plastics dictate that they cannot be laser marked, the plastic can be modified via chemical additives to ensure it is laser markable.

Yes, laser marking can be done on irregularly shaped surfaces to apply barcodes, QR codes, logos, and other identifying marks.

Laser marking systems generate less heat than other laser part marking processes. Though this method does not penetrate the surface materials and other processes are better for permanent marking.
